60m update to IARU Region 1:

If after you have updated PowerSDR to 2.8.0 and your Flex Radio is Turfed to "Europe" or some area that now has 60m Transmit
but you have trouble transmitting, you can download a text file containing an example of <Key> values you should find in your Radio's Database file. Click on the button for your radio: Flex-1500, Flex-3000, Flex-5000
These are the 60m calibration <KEYS> from my Flex radios.
You can search your radio's database file (folder: %userprofile%\AppData\Roaming\FlexRadio Systems\PowerSDR v2.8.0\)
Open up your database file: database_RevQ_F5K_1234-5678.xml (but with your serial number)
and see if any of these <keys> are missing or corrupted as compared to my database (found in 1 of the 3 files above).
If your 60m values appear to be missing or incorrect, use the calibration values from my text file to modify your database file.
Now if you are satisfied that you have modified your database file values, and didn't mess anything up,
you can save these new 60m values to the Flex-1500 EEPROM by opening up PowerSDR and hitting SHIFT + CTRL + C keys

Then click on the "Save Calibration values to EEPROM" to update your Flex radio using your current database file as the source.
(WARNING: You could make things worse if your database file calibration is not correct and you perform the step above.)


PowerSDR Installation Video:here

If you are updating PowerSDR and find the "Incremental Installer" gives you an error (like a missing network resource), it could be a registry issue preventing the older PowerSDR version from being uninstalled first.
Try Uninstalling PowerSDR directly from Windows Control Panel->Programs and Features->PowerSDR ke9ns 2.8.0.xx.
If you cannot uninstall, then download this Microsoft program and run it to fix the issue: MicrosoftProgram_Install_and_Uninstall.meta.diagcab

Below is a youtube iphone video showing how to install the ke9ns PowerSDR Rev T9 and higher

Click here to go to middle of page for more detail on how to compile open source PowerSDR.

Windows PC (Setup) to help prevent High CPU usage


CPU % not functioning or Temp & Volts not working:

Click Start, type "cmd" in the Search box.
Right click cmd.exe, and select Run as administrator.
At the prompt, type lodctr /R and press ENTER. (note the "R" is a capital letter)
This will repair the PerfMon pointers (those are stored in the registry).
You should see this message if the process was successful:
Info: Successfully rebuilt performance counter setting from system backup


NOTE: FT8 & JTAlert-x have a rather large penalty on your CPU in a crowded band (like 80m and 40m) trying to decode 20 or so signals simultaneously. The more signals to decode, the higher CPU. My old 4 core cpu maxed out at 100% decoding on 40m and running PowerSDR at the same time.

I decided to upgrade my desktop motherboard to an AMD Ryzen 6 core (12 thread) and 16gb of DDR4 is more than enough horsepower to run everything and anything, and allows PowerSDR to run at 30fps and the analog meter movement to run at 40msec with 3 - 6% cpu

"Change Active Hours" (Win10)
In Windows 10, go to "Windows Update" and change your "Active Hours" to reflect your time on the radio to prevent a windows update during the time your using PowerSDR.

Privacy Settings (Win10)
Windows 10 you will want to turn all the new privacy settings and "how updates are delivered" to OFF (block) . Otherwise your computer will be allowed to constantly send data not only back to Microsoft & others, but allows others to use your computer as an "Update server".

Microsoft "Store" (Win10)
Open Windows STORE app. In the upper right corner ... click and select setup. Turn off automatic updates of Apps,otherwise Windows 10 will be constantly downloading and installing apps while PowerSDR is running.

Microsoft monitoring (Win10)
Turn OFF "Microsoft Compatibility Telemetry" (huge drive and cpu usage hog that can start running in the background at any time while running PowerSDR) (text procedure to disable it here)

Turn OFF the following Windows "Task Scheduler" items:
---- Microsoft Compatibility Telemetry (huge drive and cpu usage hog)
---- Customer Experience Improvement
---- Power Efficiency Diagnostics
---- Windows Defender (start hard drive scans manually yourself when you want )
---- Media Center (Since it Windows 10 no longer allows the program to run)

Turn OFF the following Windows "Services":
All the "Diagnostics ..." services including: policy, service, system, Tracking (assuming all your components are working)
Lfsvc: Geolocation service windows 10
Fax: fax
Homegrouplistener: Homegroup HomeGroup continuously scans your network for files, printer, devices, data
Homegroupprovider: Homegroup
Media Center: continuously scans your network.
WMPNetworkSvc: Windows Media sharing
Windows Search (indexing) continuously updates its index files every single time a file is created, which keeps the CPU(s) & Memory & HDD busy.

Turn OFF network Printer SERVICE: HP and others have poorly written network printer Services that will continuously eat up CPU & Network.

Turn OFF MSCONFIG STARTUP programs that check themselves for updates (i.e. java, adobe, apple. do the update checks yourself). You can use free CCLEANER.exe to find them and disable them.

Schedule your Virus Checker program to update itself & scan at off hours. Dont run the virus scanner when you are using the PC.

Many Virus scanner program do background optimization without your knowledge. Usually the only way to quiet them down is to put them into Gamer Mode or Silent Mode.

Disable Windows automatic updates. Do the checks yourself.

Leave your computer ON, set for HDD & monitor to turn off after 20min of no use. This way the OS doesnt spend time after start-up to do housekeeping.

Some Video card drivers(i.e. Nvidia) include Gamer previews that download and update without your knowledge. You will want to make sure you check the "Task Manager" to see any programs that are running and delete them. If you have an NVidia card you will want to check this link to turn off the Nvidia PowerMiser feature: here

Run "Task Manager" (right click on the task bar and select "Start Task Manager" then click on the "Show processes from all users". This will show all the hidden processes that require ADMIN privileges to stop. Check them to see if any sneaky programs are running.

IF YOUR VIDEO CARD IS POOR: Go to System Properties-> Advanced ->Performance Settings-> Visual Effects->Adjust for best performance (to turn off the graphics extras that you probably dont need)

To speed up your computer, get a new Solid-State Hard drive, and a Gamers video card.

To Enable/Disable Windows Services: Click on the Start button and type "services" in the search window.
Click on Services (local).

Right CLICK on the task bar (bottom of the screen) and select "Start Task Manager", then click on the "show processes for all users" down at the bottom.
Its good to print this screen out for future reference when your computer starts to "act" up.
Kill rogue programs that are running in the background (like java update scheduler, ituneshelper,etc.).
Also, check the "Task Scheduler" to make sure Windows or other programs dont run a schedule task while your operating.


Programs to Download and Install besides PowerSDR
(These programs are explained further down below)

1) VspMgr (free): Allows you to create Multiple pairs to serial ports for using CAT commands to allow other PC software to control your Flex. I create 6 pairs of extra COM ports.

2) DDUtil_V3 (free): Scans the CAT port you assigned in PowerSDR (setup -> CAT Control) and allows you to map the PowerSDR COM port to multiple COM ports created by VspMgr. This will allow you to have multiple PC programs all talking to your Flex at the same time.

3) VBCable (free): Creates a Virtual Audio Channel (in & out) which allows your Flex to send/receive audio from the PC. The paid version allows for multiple channels.
4) "Virtual Audio Cable" (paid): by Eugene Muzychenko for the paid version

5) HRD (free): Ham Radio Deluxe last free version gives you a Log book and digital modes that link to the flex via a CAT COM port.

6) Fldigi (free): Multiple Digital modes (now located on sourceforge as a setup file)
Here is the PowerSDR.xml file, unzip and drop in the folder with fldigi. Just right click on the fldigi icon and open file location

7) EasyPal (free): Allows you to exchange quick Internet pictures by sending links to them over the radio. Also allows for Waterfall callsign ID images.

8) wjst-x (free): FT8 digital mode and more.

9) JTAlert-x (free): keeps track of needed contacts and prevents dups (has a callsign database download as well).

10) EIBIview (free): Full list of Short-Wave stations (including DRM) can be sorted by Time, Location, or Language.


Audio Folders (location of REC / PLAY), MP3 & PowerSDR Database

The QuickAudio file names now contain a sequential index value + Mode + freq + date + time of the recording
Every time you hit the REC button a file "SDRQuickAudioXXX.wav" is created in the folder:
%userprofile%\AppData\Roaming\FlexRadio Systems\PowerSDR v2.8.0\QuickAudio\
(Right Click on the PLAY button to open this folder)

and (Wave->MP3 folder) an "SDRQuickAudioXXX.MP3" is created in the folder:
%userprofile%\AppData\Roaming\FlexRadio Systems\PowerSDR v2.8.0\QuickAudioMP3\
Click on the "Wave" button then "MP3 Folder" button to open the MP3 folder directly.

The file location of the "MEMORY" scheduled recordings (MP3), and the orignal "Wave" folder recordings is:

PowerSDR "MEMORY" data, and DX Cluster data files:
%userprofile%\AppData\Roaming\FlexRadio Systems\

PowerSDR Database files (look for your radios serial number in the file name):
(original) %userprofile%\AppData\Roaming\FlexRadio Systems\PowerSDR v2.7.2\
(new ke9ns) %userprofile%\AppData\Roaming\FlexRadio Systems\PowerSDR v2.8.0\


Griffin Powermate for frequency tuning

Griffen PowerMate Drivers are now Written directly into PowerSDR ke9ns v2.8 (setup->general->user interface).
If you are running PowerSDR ke9ns v2.8 then skip this section.
This section and these files may be useful to other SDR users not running PowerSDR ke9ns v2.8

I wrote 3 programs (below) that Force the Griffin Powermate Knob to send Frequency change commands to PowerSDR no matter what you doing on your computer:
1) AutoFocuses the PowerSDR window and sends Keyboard Shortcuts AND also allows Remote Knob Operation (but without the AutoFocus)
2) Sends CAT commands to a COM port connected to PowerSDR
3) Same CAT commands, but with a Signal Strength Meter added.

NOTE when using any of these programs:
Do NOTrun the PowerMate program you normally use with the Knob (look for the knob image in your tray).
Windows should install the Griffin driver automatically.

1) PowerMate/PowerSDR using keyboard shortcuts (i.e. PowerSDR only)
NOTE:This version now allows remote operation over a "Remote Connection" but does not autofocus the PowerSDR window on your "Remote Connection". BUT, if you are running it locally, it will still auto focus to PowerSDR.
Do NOTrun the PowerMate program you normally use with the Knob (look for the knob image in your tray). Instead download this zip file, unzip the folder and keep the 2 files together. Simply run the .EXE file (but in ADMIN compatability mode). Just minimize to the Tray and leave it running all the time PowerSDR is running. You will need to have .NET 4.0 framework installed.
This will work with the new PowerSDR 2.7.2 ke9ns revisions, BUT you must run "PowerSDR", then run "Ke9ns PowerMate", then its OK to open the DX spotter window. It must be done in that order using this version.

2) PowerMate / Flex Radio CAT commands
This PowerMate version does not change Window Focus, it simply opens up a COM port that links back to the CAT for your radio.
I use ZZAD/U commands for VFOA with 3 selectable step rates: (100hz,1khz,or 10hz).
I use ZZRF for the RIT function (+/-10hz steps). I could not use ZZRU/ZZRD for RIT because DDUtil gets caught in a loop.

Download this zip file, unzip the folder and keep the 2 files together. Simply run the .EXE file (dont need ADMIN permission). You will need .NET 4.0
The default is COM7 (you can select 1-16). You will need to use a program like "vspMgr" to create virtual COM port pairs (i.e. virtual COM6-COM7 pair), and DDUtil to link 1 side of each COM pair back to your CAT rig. (i.e. set RCP1 in DDUtil to COM6)

3) Flex Radio CAT commands RX Signal (with Powermate)
Download this zip file. This version (again dont run PowerMate Editor) can work with or without the PowerMate (but you still need to install the driver). The meter skin is called Met2.jpg and is replaceable. Just keep the skin in the same folder as the .exe and .dll files. Now the Meter movement is smoother and the needle is smoother.

The meter image is my tribute to the TR7.

Below is a short youtube iphone video I took showing the above ke9ns powermate software running.


PowerSDR Skins
You can copy the default skin to use as a starting point for creating a new skin.
Skins under V2.7.2 are found in the following location (Click on the START button and enter the following in the search window): %ProgramData%\FlexRadio Systems\PowerSDR\Skins\
Highlight the "Default 2012" folder and press CTRL C
, then CTRL V
You will now have a new Folder called "Default 2012 - copy"
Right click on folder and rename it your call sign (ie. KE9NS)
Navigate into the new FOLDER inside the "Console" folder. These are the files you can change.

In my KE9NS example I changed the "picDisplay.png" file which is the background of the Panadapter.
Started from scratch with Adobe PhotoShop.
1) Create a new picDisplay.png file with a canvas of 1000 x 550 (the standard skin is a 100 x 50 image, but that will be too blurry if we add a call sign).
2) Pick a background color (use the eyedropper tool to pick a color from some other image), and use the paintbucket tool to fill the canvas.
3) Now add a background lighting enhancement, so click on Filter->Render->LIghting Effects->have fun. The image on the left is virtually lit from the bottom right. The image on the right is virtually lit from 3 sources above the skin (like on old radio with light bulbs over the dial).
4) Now add your callsign to the image in the upper left corner. Pick your Font (i used LCDMono) and size (i used 72pt) and Opacity I added a lensflare (Filter->Render-> Lens Flare) just to the callsign.
5) Next, I replaced the slider(s). RX2 sliders are slightly smaller,so there are 2 sizes.
6) Since the slider we are creating is round,and all image formats save files with 4 sides, we need to create a cavnas with on opaque background (i.e. a see through background), it shows up as a checkerboard pattern in Adobe.
7) I found some knob images on the web and scaled them down to fit.

I have now also included a background without the call sign but with a robinson projection.

The slider replacements are slightly larger than the original 20 x 20 and 16 x 16. My Slider(s) are 22 x22 and 19 x 19 (see below)

Click here to download the skins (without my call sign)

At this point go to PowerSDR -> Setup -> Appearance -> and select the new skin.

The Panadapter will now look like the photo at the top of this page.
At this point its best to shut down PowerSDR and reboot your computer.


FireWire IEEE 1394 Interface (driver issues)

FireWire (IEEE 1394):

If your having trouble getting your Flex-3000 or Flex-5000 to connect to your FireWire card, it may be the driver.

When Windows does an "overnight update", it sometimes updates the FireWire 1394 OHCI driver (switches drivers), which ends up causing trouble for some older hardware. (i.e. Your Radio works one day, but not the next)

Microsoft Support if your Window 8 or Windows 10 FireWire card stops working or acts strange.
Read and follow this link to fix it:

Download: 1394_OHCI_LegacyDriver_x64.msi
Download: 1394_OHCI_LegacyDriver_x86.msi

NOTE: If you are having troubles running a Flex-3000 or Flex-5000 at 192k sample rate, try the Legacy Driver. And change the sample rate only from within PowerSDR: setup->Audio->Primary->Sample Rate

FireWire issues and changing the driver to "Legacy"

Device manager will list your FireWire card as: IEEE 1394 host controller (Either LSI, TI, or VIA 1394). Via works for me.

If your buying a new 1394 FireWire Card, make sure it is now Windows 10 compatible:

This is an 1394 FireWire ExpressCard for Laptop computers with ExpressCard slots (preferably ExpressCard 2.0). ExpressCard is really just PCI Express in a different format

This "PCI Express" card uses the VIA VT6307 chip and is Drop-In compatible with Windows 10 and was bought on Ebay for under $20

Flexradio.exe app Go into Flexradio app
1) set Operate Mode to "Normal". Click the DPC button to confirm the Firewire connection has low latency. If not, check your PC for un-needed and unused programs. You may need to reinstall the OS for a clean start. High latency will cause very strange audio issues. You will eventually see a few time the computer encountered high latency, hit the Clear button to make sure it doesnt happend that often.

2) Buffer size: Dictated by the PowerSDR -> Setup. So dont try and change it here.


PowerSDR Noise Cancelling or Signal Enhancing

If you have a Flex 5000a with the 2nd receiver option (RX2) and are running PowerSDR 2.7.2 you can use the ESC "Enhanced Signal Clarity" feature to reduce noise on the band using a 2nd antenna (RX2). The RX2 antenna needs to pick up the noise as strong or stronger than your main antenna (RX1). I use a vertical for RX2 and a Yagi or G5RV for my main RX1 antenna.
My Vertical tends to be very noisy, and my horizontal antennas tend to be very quiet.

ESC "Enhanced Signal Clarity" works by allowing you to sync both RX1 and RX2 receivers together, then allows you to change the phase relationship of RX2 vs RX1. Noise Cancelling happens by moving the RED target around until the noise is subtracted from the real signal. It works very similar to a noise cancelling headphone: detect the noise and inject the same exact signal 180 degrees out of phase to cancel it out of the original signal (i.e. Null Forming). A perfect solution would be an RX2 antenna that picks up nothing but noise since its possible to cancel out the real signal as well.

The additional benefit is that you can improve a weak signal as well, by aligning RX1 and RX2 signals to add, rather than subtract.

Below is a short youtube iphone video I took showing how well ESC works for Noise Canelling using a G5RV on RX1 and a Vertical on RX2.

I found that after you ENABLE the ESC feature, you can now turn off RX2 (the RX2 button in the lower left corner of PowerSDR) and set the RX1 display back to PANFALL and the ESC will still work.



PowerSDR remotely from anywhere using: RDP
Remote Desktop Connection

You may not know it, but built into Windows is "Remote Desktop Connection". This will allow you to fully operate PowerSDR remotely (both transmit audio and receive) to any other Windows device running the same "Remote Desktop Connection". Its located in C:\Windows\systems32\ and actually called mstsc.exe. (or you can just search for it)

See above: I now have a version of the Griffen Powermate software to allow remote use of the Knob when using Remote Desktop Connection.

Note1: The Remote Desktop app is not the same as "Remote Desktop Connection". There are many versions of Remote Desktop and none allow remote microphone audio to be sent back to the local computer. There are some programs that can be purchased that allow remote microphone audio, and you could use Skype to complete the missing microphone audio, but there is no need if both computers are Windows PC's


Control Panel. do a search for "Edit Group Policy". Then Click on the "edit group policy" link
Local Group Policy Editor->Computer Configuration->Administrative Templates->Windows Components->Remote Desktop Services->Remote Desktop Session Host->

Device and Resource Redirection->Limit Audio Playback Quality->Enable->High

Below is a short youtube iphone video I took showing how to setup "Remote Desktop Connection" and use it.

1) On your HOST Flex Computer:
You need to allow Internet Port 3389 to pass through your Modem, and Router to your local comptuer running PowerSDR. Open your Modem and/or Router config page and port forward 3389 to the local IP address of your PowerSDR computer (the IP is usually something like 192.168.x.x). This now allows all external Remote Desktop data to tunnel from the Internet directly to your local computer.

2) On your HOST Flex Computer:
You must authorize Remote Desktop to allow specific users to access your local computer.To do this, Do a windows search for: systempropertiesadvanced, then click REMOTE tab, then click allow users, then click select users. Add your current user as a Remote Desktop user. By default your main user account should already be authorized to have remote access. If you normally turn on your computer and you dont need to type in a password to get to your desktop, then you will need to go to the User Account panel and add a password. Remote Desktop Connection will not connect to a computer account that does not have a password.

3) On your Remote Computer:
In RDP show options -> local resources -> Remote Audio -> settings -> "Play on this computer" and "Record from this computer"

If PowerSDR is not already running on your Host Computer, you will need to Set local resource audio in RDP on your remote computer to "Play on remote computer", log on and run PowerSDR, leave it running and log off RDP on your remote, set local resource audio in RDP back to "Play on this computer and Record from this computer", and log back in to your Host.

4) Go to and get an free permanent URL address that is linked to your Routers Internet IP address. Your Router should show you what your current Internet IP address is when its connected to the internet.

5) ON the Remote Computer:
Search for "Remote Desktop Connection" and copy a shortcut onto your Desktop and run it now. Type in the IP address or new URL address of your local Flex computer (not the local IP address 192.168.x.x of your Flex computer). Then select Local Resources->Remote Audio->Play on this computer & Record from this computer.

6) Now Click Connect and type in the Password that you normally log into your Flex computer with. When connected you will see your desktop and PowerSDR app running.

7) For Tx/Rx Audio to work, you must activate the VAC1 or VAC2 button on PowerSDR. VAC1 or 2 must be setup so the input = Primary sound driver and Output = Primary sound driver. This will allow your Flex computer to connect directly to the DEFAULT MIC and Speaker of your Remote computer.

Note: if you use VAC2, then you must also use TX VFO-B on PowerSDR.

Note: Make sure to use "Windows DirectSound" for VAC1 or VAC2. It has the least amount of lag compared to "MME"

NOTE: Its best to run PowerSDR console in the smallest configuration possible to reduce the internet bandwidth. Below is the minimum size I run when in remote operation: (This keeps the panafall area small but usable)

NOTE: Make sure the Sample Rate (i.e. 48000) of the VAC input and output channels match from the PowerSDR side to the Windows PC side (right click on windows tray speaker icon->Playback and Record devices).


PowerSDR Virtual Audio Cable

Virtual Audio Cable takes the place of the MIC/LINE IN & AUDIO OUT jack on the back of the PC.
Audio is sent/received via the FireWire cable keeping it digital and eliminating extra cables.
VAC1 allows you to map RX1 to your PC.
VAC2 allows you to map RX2 or RX1 to your PC
You can MAP the INPUT/OUTPUT to the standard Speaker/MIC of your PC, but there is a better way:

Download "VB-Audio" (a free program):

NOTE: Uninstall Pack42b, It does not work properly under Window 10

VB-Audio provides a single virtual cable for your IN and a single virtual cable for your OUT.
VB-Audio labeled the devices backwards, so "CABLE Ouput" device is really an Audio INPUT device (just like a Microphone).
"CABLE Input: device is really an Audio OUTPUT device (just like your PC speakers).

The Free version gives you just this one pair of CABLE's. The Donation version allows multiple CABLE's.
Some PC programs that use Audio In/Out devices dont properly use these VB-Audio Cables.
That forces you to apply a couple of tricks to get them to work:
Trick #1: Select the DEFAULT Playback and Recording devices on the PC to direct (see screen shots below)
Trick#2: You may need to set PowerSDR to use the "Default" IN/OUT devices instead of the VB-Audio Cables.

See the Image above (right): Note the "Stereo Mix: device that is normally not preset unless you install the drivers from the audio mfg. You will need this in order to use a MIC on a Remote Desktop computer.

You must configure VAC1 as found in step 5) way above.

Now back on PowerSDR, you can MAP the VB-Audio CABLE IN/OUT devices to the IN/OUT of the Flex.

Setting up the VAC program:
Since Windows is set to 44100 by default, You can simply set the PowerSDR sample rate for VAC1 and VAC2 to 44100
(some digital programs use 48000)


CAT & Virtual COM (serial) Port

External Devices & PC programs can communicate with the FLEX via CAT, either via the I^C DB9 connector on the back (for real Devices) or via a Virtual COM port (transfering data over FireWire cable) for PC programs.

For 32bit x86 installations:

1) Free Download and install SetupVSPE.msi (Eterlogic)
2) Run the VSPE program
4) Let it create the pair using the next 2 available COM ports
5) Minimize the VSPE program (to the task bar)

For 64bit x64 installations:

1) Download VSP Manger by k5FR (vspMgr.exe)

Notice I created a virtual pair COM2 <-> COM3, COM4<->COM5 and COM6<->COM7:

Set up the Flex CAT to COM2 and the Flex PTT to COM5:


Download DDUtil_V3 (free)

Setup the Radio Select to your Radio and COM3 port that connects back to the COM2 of the Flex through the Virtual com port you setup previously.

Now add RCP's to give you multiple COM ports (COM6 will be controlled by DDUtil, and you connect your program to COM7. If you have more PC programs, then create more virtual pairs. so COM10 connects to COM11, and COM12 <-> COM13, etc.)


Below is a short youtube iphone video I took showing how to create multiple Virtual COM Port pairs:

Antenna Rotor Control:

If you want PowerSDR to be able to control your Antenna Rotor, This is my example setup:

I have a real COM1 on my PC
I have a bunch of virtual pairs as follows:
COM16 <> COM17

PSDR->setup->Cat control->CAT port COM2
PSDR->setup->Cat Control->Rotor port COM17

This just sets up the standard CAT link to PowerSDR


check box: Model Hygain for Rotor 1
Set Rotor to COM1 and the correct Baud for your rotor
Check Enable (which opens up a rotor direction panel)
to test, you should now be able to enter an angle into this rotor panel, and move your rotor.

Now This is the Rotor setup link back to PowerSDR:

DDUTIL->setup->ports->RCP1->Rotor Port->COM16 (same row as RCP1 COM8 from above)

Now when you click on the "angle" part of a line in the DX spotter screen
PowerSDR will send an hygain command from COM17 to COM16

DDUTIL will relay the Antenna direction command from COM16 to COM1



Flex 5000 Station Setup (click to enlarge)


NOTE1: This setup permits ANT3 use the Linear AMP, and RX2 can either tap the same ANT3 or a different ANT1

Note2: The G5RV has ground radials under it and so can be configured for 160m by a modified RCS-4 coax switch box (see Antennas section of my web site)
Note3: SO2R: Single Operator and 2 Receivers switch box allows any configuration of up to 6 antennas between the 2 Receivers.

"ANT3" is RX1 and goes to the Amplifier, that way RX2 can be either "ANT1" or "RX1 Tap"
"RX1 in/out" is for the AM Broadcast filter (aluminum box down and right side)
"Balanced Line" input for the Studio Mic has been converted to a Combo XLR/TRS connector.
"PTT IN" goes to a Hand Held Push Button on the desk when using the Studio Mic
"PWR-SPKR" goes to a powered Stereo speakers (with Sub-Woofer) and Desk Volume control
"TX3" jack is used to key the Amplifier (not shown)

"FireWire" cable directly to the PC with multiple ferrites on both ends of 6' cable (not shown)
Also not shown is a full coax choke (with ferrites) between the Amplifier and the Ext Ant Tuner, and another coax choke between the Flex Ant3 and the Amplifier.

General PowerSDR Settings for max operation


PowerSDR.exe app Go into PowerSDR app and click on "Setup".
1) General->Options settings
Process Priority to "HIGH" or "REALTIME" (if you have a really fast computer). REALTIME can sometimes cause strange behavior if your computer doesnt have the horsepower.

2) General->Filters: reset filters for 9999hz

3) Audio: Primary Buffer (lowest possible, but with no sound output issues) 1024 works, but NR and ANF dont work well. Set to 2048
4) Sample Rate: 192000 (better audio and larger Panadapter window)
Mic Boost = ON, because we need to turn the MIXER MIC input down half way. (this arrangement seems to work better)

5) Audio: VAC use for digital modes, or remote operation modes. The image is VAC1 using VB-Audio software (Free) for RX1. The sample rate should be 44100 for everything that uses the VAC (both in PowerSDR and your digital software)

6) When using RDP "Remote Desktop" set to the following to get audio to/from the remote PC. The image below is VAC1 using Sound Mapper for RX1. VAC1 works with VFO A and B. VAC2 works with either receiver, but appears to be designed for RX2 & VFO B. To select VFO B simply click on the TX button in the VFO B window

You may need to make sure your Flex PC has the STEREO MIX listed under RECORDING devices in the Audio Section of Windows. STEREO Mix usually gets installed when you install the device driver provided by the sound chip mfg. (not the driver Windows finds/installs for you). With the setup you see below, you can plug a Mic/headset into your PC and use it with the Flex. (or remote mic/headset). You just need to make sure the default Playback device is your PC speakers and default Record device is your PC mic input.


7) Display: Update Period: 20-30ms (keeps your waterfull up to date quickly when you change frequencies, but higher CPU usage
8) Display: Low Level - High Level: adjust per antenna and band for a slight blue color in the background with no signal.

9) DSP: Options: 4096 Buffer size get you the sharpest filters but more delay.
10) DSP: AGC/ALC: disable Leveler (otherwise you will get weird audio undulations.)

11) For SSB Transmit: save a 4K profile name. HIGH=4000, LOW=100, for eSSB save a 6.5k profile name: HIGH = 6500, LOW=0

12) For AM Transmit: save a 10k profile name. High = 5000, low = 100, AM Carrier level= 20. (leveler is OFF). Adjust your Drive carefully to allow for 1.5x (compared to your carrier level) when you speak). Your Carrier level needs to be adjusted according to what you AMP can take.

13) MIXER: whatever MIC input you use, move the slider down around half way. But you need to enable the MIC BOOST from Step 4)

14) MIC: set the MIC gain half way (around 32)
15) You can use the CPDR half way (around 4)
16) You may need to enable MIC BOOST (back on item 4) Settings->Primary->Audio

17) Make sure the TX MIC output meter does not go over 0db
18) Make sure the TX ALC output meter does not go over 0db


Flex 5000 AUDIO Setup

I now use a audio-technica BPHS1 studio headset/ dynamic microphone (40-20,000hz) on the Right Channel
(The "Dynamic" design is very compact & provides much less noise pickup)

and my Marshal MXL990 Condensor microphone (30-20,000hz) on the Left Channel
(The "Condensor" design is large & provides mega deep base, but is very sensitive and picks up external noise)

LEFT: Gain = 32db, low cut ON 20 hz (adust to get -20db out level)

(make sure your input level peaks around -20db)

RIGHT PEQ: (setting for 3-6khz wide SSB audio using my audio-technica BPHS1 studio headset with a dynamic microphone with a 40hz to 20khz range)

Below you can see where the XLR / TRS Combo Balanced line connector goes. I added shielding over the connector when I was done.
You cant quite get the XLR/TRS Combo connector close enough to the original TRS hole, so there is a small gap between the XLR and panel in the top right of the above picture.



Flex Power Amplifier (PA) and SWR Calibration

This is a Hidden menu function and requires an Array Solutions, Inc. Power Master 1 Calibrated SWR/Watt meter.

Focus on the PowerSDR window and press the following keys: <SHIFT><CNTL> F

DO NOT touch anything on this page unless you are willing to brick your radio if you mess up.
DO NOT touch the Input/Ouput side of this window ever.

Calibrations will NOT work correctly unless you are at Factory Defaults.
DO NOT run any other programs on your PC

Select 1 Band that you would not normally use, just in case you mess up. (like 30m)


This zip file contains a folder with the latest PowerMaster 1 firmware, manuals, and Windows PC programs to communicate with the PowerMaster via the serial port. Click to download PowerMaster ZIP File

1) To run a PA calibration you need an "Array Solutions PowerMaster 1" meter (original, NOT the Powermaster II )
2) Connect the Serial port to your PC (I use a Serial to USB converter, then set the USB driver to COM1, an unused COM port)
3) Install and run the free Power Master basic PC program to verify you can communicate with your Power Master original.
4) Attach the Power Master coupler to ANT1, then to a 50 ohm DUMMY load capable of over 100 watts.
5) Attach a 25 ohm DUMMY load to ANT2 all by itself. [Take (2) 50 ohm DUMMY loads in parallel to get 25 ohms]. ANT2 is used very briefly during the SWR calibration, so you dont need a large capacity 25 ohm DUMMY load. I just used a high wattage 25 ohm resistor used in RF applications.
6) Export your current database to your Desktop, you will restore back when your done. (see Settings menu, bottom strip)
7) You must restore the PowerSDR to FACTORY DEFAULTS (see settings menu , bottom strip, left side)
8) You must create a empty text file called: production. (no file extension) in the hidden:
%userprofile%\AppData\Roaming\FlexRadio Systems\ (this is to activate the grayed out buttons on this screen.
9) <CTRL><ALT>S to active the SWR button
10) You must create a powermaster.txt file in the C:\ProgramData\FlexRadio Systems\PowerSDR folder. Click here for a sample file. You insert the gain or loss values for your particular Power Master coupler. (its written on the HF coupler). But, the Power Master coupler gain/loss is generic for the entire HF band, where the powermaster.txt file breaks it down into each band. You may need to tweek each band value seperately.
The Powermaster coupler correction values will scroll onto the Production PA test right side window. They wont match the values in the powermaster.txt file because they are multipled by the built in PowerSDR gain/loss values for the Flex radios circuits.

Your Ready to start Calibrations:
11) Click Bias button will adjust the Driver and Final Bias values for specific Transmit Idle Amp values. No external equipment needed.
12) Click the Null Bridge button and a mV scale will pop up next to the Verify button, then manualy adjust the C45 var Cap on the power board inside the Flex-5000 for lowest mV value. The Flex will transmit around 40w to 60w through ANT1
13) Click on the ABORT button when you have the lowest mV reading possible.
14) Click on Clear All button
15) Click on only 1 band to calibrate (an unimportant band to start with)
16) Click on Run PA Cal button. The Flex will calibrate for 1w, 2w, 5w, 10w, 20w, etc. to 100w on ANT1
17) The Flex will then switch in ANT1 and ANT2 to calibrate the SWR for a 2:1 ratio
18) When finished, the PowerSDR will save new EEPROM data to the Flex (whether the Cal succeeded or failed)
19) I believe that if the Run PA Cal turns Yellow after the calibration of 1 Band; it passed. Green would be if all bands passed. Red means something failed.

The Verify button will try and output 100w on the selected bands as a pass / fail (I believe a 4watt deviation is allowed to pass). It doesnt need to be done on bands you just did a Run PA Cal on.

The Power button (below the Run PA Cal button) causes PowerSDR to crash, dont touch it.
You may lose transmit capability on the band you just attempt to calibrate if the calibration failed to finish properly. You will need to shut down and start over.
If the calibration crashes, you will lose transmit on the band you were calibrating. You will need to shut down the flex and start over.
If the power master loses communication with the flex, you will need to shut down the flex and start over.
if you see a NaN for SWR, then the SWR calibration failed. Try again.
If the 100w PA calibration fails, the SWR calibration will likely fail. I believe this is a software glitch.
if the SWR fails, you can manually click the SWR button to run just the SWR test over again.

The calibration may not be able to properly calibrate a particular band to 100watts. This may be the due to incorrect gain/loss correction values in your powermaster.txt file, or something wrong with the radio. If the Run PA Cal routine finished you will still be able to transmit, you just will not be able to make 100watts at full power. The max watts out will be whatever the routine topped out at.

Below is a short youtube iphone video I took showing how do the PA Calibration.


Press <CNTL><ALT> B: Image on right side lower right corner: allows for Class A (instead of the normal Class AB)
This was kept hidden because Class A will get the finals very hot. Limit your output to 20watts only. Change the 1 and 2 to 2 and 4 and Click on the Bias to readjust the Bias



Flex Receiver / Transmitter Calibration

PowerSDR 2.7.2 GPL (General Public License) source code

This mod project was started 1/1/2016 by me, Darrin KE9NS and is based upon
the GPL Open Source PowerSDR 2.7.2 SVN: 5123 code provided by Flex Radio Systems, Inc.
With generous help provided by Flex Radio Systems, Inc. (Thank You!)

This Source code includes 4 project under the PowerSDR umbrella: DttSP written in C, PowerMate written in C++, PowerSDR written in C#, and Visual Studio Installer (to create the installer)

DttSP and PowerSDR code was provided by Flex Radio Systems, Inc.
PowerMate code was provided by Griffin, Clev R. Munke, and me Darrin ke9ns
PowerSDR modifications beyond 2.7.2 are provided by: me Darrin ke9ns, and dh1tw for the DJConsole code
SWL.csv file from (thank you)
SWL2.csv file of my own with additional short wave stations. It is automatically added to the SWL list
dxloc.txt file initially from HRD (thank you), modified by me Darrin ke9ns

Currently compiling under Visual Studio 2017 (VS2017) v15.5.3 and NET 4.5.2
After you download and install VS2017, you must then download and install any VS2017 patches.

NOTE: Sometimes the visual design form can become out of sync with its underlying.cs code file, for example, you remove code pointed to by an element on the Form, the Form will not open for display, even if you put the code back.
If Visual Studio Refuses to display a Form, Close the offending Form (not the project), then click Build->Clean Build, then Rebuild. Now reopen the offending Form and it should open up properly now.
Also, this means its best to make a CTRL C , CTRL V copy of the entire Project after a successful update and run. This way if you accidently break the code, you can use a file compare program to determine what you broke.

You can run the build from within VS or directly from the VS project release or debug folders.

PowerSDR.exe and PoweSDR.config.exe are the only files needed in the PowerSDR build.
DttSP.dll is the only file needed in the DttSP build.
PowerMate.dll is the only file needed in the PowerMate build.
ALSO: vcruntime140.dll needs to be copied onto the target computer (PSDR program files folder, or download the free C++ VC2015 runtime installer)

Also, I have 2 installers: 1) a Full installer using "INNO Setup", and 2) An Incremental installer using" Advanced Installer"

Do a full rebuild the first time you open the project in VS, before doing anything else.

Things I needed to do before the PowerSDR would actually run:
1) Copy the project into the VS project folder. Make sure the Bin and Source folders are both directly 1 level down
from the PowerSDR_v2.8.0 project folder itself, otherwise the paths wont match up to the original project solution information, and it wont compile
2) Copy over the pal.dll from the Standard Flex PowerSDR program files (x86) folder, into the VS release & debug folders,
otherwise the PowerSDR messes up and will ask for a firmware update.
3) Copy over the TNF.dll file from the Standard Flex PowerSDR program files (x86) folder, into the VS release & debug folders.
4) Go into the VS PowerSDR "references" -> Browse, and add the TNF.DLL to the list. Navigate to the Relase folder you placed it in.
5) Go into the VS PowerSDR "properties" and remove the NO_TNF reference from the "Build" compile list (you need to do this 2 times: Debug and Release)
6) Copy over the ATU.dll file from the Standard Flex PowerSDR program files (x86) folder, into the VS release & debug folders.
7) Go into the VS PowerSDR "references" -> Browse, and add the ATU.DLL to the list. Navigate to the Relase folder you placed it in.
8) Go into the VS PowerSDR "properties" and remove the NO_NEW_ATU reference from the "Build" compile list (you need to do this 2 times: Debug and Release)
9) Rebuild the solution: Release or Debug. Now you will have a full working PowerSDR version that you can start your own modding
10) Remember PowerSDR C# is based on 96dpi resolution and Photoshop default is 72dpi, so images created on Photoshop will be too big unless you set the DPI to 96 and then select your canvas size in pixels.

It would be nice to add more features to this PowerSDR ke9ns project based on others source code additions.


NOTE: v2.8.0 requires vcruntime140.dll. The Installer copies this file over, but If PowerSDR still fails to run,
you can download the Microsoft installer:


I uploaded the original Flex GPL 2.7.2 source code to Bitbucket ( in order to keep track of all the changes I have made from the original GPL source code.

PowerSDR KE9NS "Voacap" Propagation Mapping:

ss:0 ef:15 SpW:
(ss) is the official optical sunspot number from SIDC. The higher the better.

(ef) is the effective sunspot number, which is based on soundings of the ionosphere, but only for the mid latitudes of the earth.
The effective SunSpot number is more accurate than the optical. The higher the better.

The only number you want low is the (K) (high K means signals will likely be scattered rather than reflected)

VOACAP propagation uses the (ef), so its more accurate, but it doesn't take high (K) values or (SpW) geo storms into account.
VOACAP propagation assumes you have a rotatable dipole or 3 element beam at 35' (if you select it)

Dots: The Dots show signal strengths computed for the exact locations over the map. Areas on the map with small or no Dots have the weakest signals.
Large Dots have stronger signals. Blue is the strongest signal, then Green, then Orange, then Yellow, then Gray

Contours: Contour lines are derived by a formula from the dots, but can sometimes be difficult to see coverage gaps on the map.
Blue is the strongest, then Green, then Orange, then Yellow, then Gray.
The problem with contours is it is hard to determine the Gaps in coverage. You may see a Blue contour line, but if you change over to the Dots map, you will see no signal strength adjacent to the Blue area of the map. (i.e. a Gap)

Reasons you may hear stations when the Propagation map shows no conditions:
Some Ham Radio stations have large Antenna arrays and may show up on an empty part of the Propagation map, due in part to their very large Effective Radiated Power (ERP) when compared to a wire dipole.
at 27mhz or above, Tropospheric Ducting Propagation maps (see
and/or Sporadic E propagation (Estimated Sporadic E layer (

You may not hear stations that are in a Blue or Green area of the map, due to Antenna directionality, takeoff angles, Geo Storms,or high K readings, or they may be in Gaps found in the propagation area


DX Cluster Lists:

See for a list of DX clusters that you can add to the list in PowerSDR Spotter window.


PowerSDR S-Meter dBm vs Panadapter dBm:
Why is the S-Meter reading showing a signal level different from the signal I see in my Panadapter bandpass?
This is because the S-Meter reading is the Sum of all the DSP FFT bins taken within the bandpass filter.
If you were to close down your bandpass to around 10hz, the signal within that bandpass and the S-Meter should now be the same dBm (if both meters are running at the same refresh rate and you take into account any averaging being done).
So, as you open up the bandpass filter, the S-Meter will rise as you add (sum) more bins.
This is as it should be and works the way a traditional S-Meter works.

Note: the S meter scale on the right side of the Padapter is approx because it only follows the dBm markings found across on the left side of the Panadapter. So in order to see a correct scale on the right side matched to the left side, you would need to set your setup->Display->Spectrum Grid->Min = -19, Max = -137, Step = 6 (S signals are 6 dBm apart). But if you use the Auto Pan Lvl button, the Max value will change automatically.

NOTE: This firmware will not disrupt any prior TURFed settings like MARS or UK.
NOTE: This firmware will not prevent you from running the basic original Flex 2.7.2 PowerSDR
First time your run T12, PowerSDR will ask you to allow the firmware upgrade. Say Yes.
If you are in IARU Region 1 with the new 60m addition, you will need to do a setup->factory defaults to reset the database in order to see the band limits.

The First time you run T12 Windows may popup a Firewall block access message, make sure to allow access, otherwise you will not be able to DX spot, or get solar weather.

Add: In "Wave" menu: add 3 Buttons to help record Voice to IDTIMER.wav, CW to IDTIMERCW.wav, or CQ call to CQCQ.wav
So you will not need to manually rename files to use with the ID timer.

Voice ID: Click the button, record your voice id, Click to save IDTIMER.wav file automatically overiding any previous IDTIMER.wav file.

CW ID: Change over to CW mode, Click the CWX panel, type your call sign into one of the macro boxes, Click the Wave CW ID button, Click the the macro box with your callsign, when done Click to save IDTIMERCW.wav file.

01/02/17 T11: Fixed GrayLine (again). Fixed: Wheel Tune didnt work when the mouse was over the date/time/cpu panel. Now it does.
01/02/17 T11: Revised Operation of the ID Timer:
Station ID Timer (10min):
LEFT Click
on the “ID Timer: OFF” (just above the PowerSDR clock). This will start the 10 min countdown timer (synced to the nearest minute, so the first go around may be less than 10 min). When the counter reaches 0, “TIME TO ID” will flash.
Right Click on the “ID Timer: xx” toggles between:
Voice timer “voID Timer: xx“: Transmits an audio file with your voice called IDTIMER.wav
CW timer “cwID Timer: xx”: Transmits an audio file with CW recorded, called IDTIMERCW.wav
Waterfall ID Timer “wfID Timer: xx”: Transmits your Callsign, that you type in the TXwaterID box found on the top line of the PowerSDR console. Make sure this box is Green.
So at the end of the count down, in addition to the “TIME TO ID”, it will transmit 1 of 3 files.
TO Record your IDTIMER.wav or IDTIMERCW.wav file: You must have wave->Quickaudio save folder enabled, then Check the “Rec/Play ID” box, hit the REC button and record your ID message, hit the REC button a 2nd time to end your message. Right Click on the PLAY button and right click on the newest file created and rename to IDTIMER.wav. After you rename the file, select IDTIMER.wav and click OPEN.
You now have a permanent ID message. NOTE: this will work for recording a CW message. If you put the Flex into CW mode, hit the REC button and tap out your callsign (or use the CWX panel), then hit the REC button again when its done sending your call, then put the Flex back into SSB. Rename this file IDTIMERCW.wav.

12/03/16 T11: Add: VOACAP optional Contour plot lines (using C/Fortran code by Paul Bourke). Add: Can now choose the accent color around the VFOA/B and Meters.

12/01/16 T11: Add: BandStack window, Delete entries using Mouse Wheel Click, Sort list with Sort button (low to high freq)
11/30/16 T11: Improve Pulser function (more accurate and stable). Improved visual changes to VFOA/B and Meters.
11/28/16 T11: Work on VFOA/B panels. Update SWL file from Move VOACAP map in front of Grayline map.
11/27/16 T11: Fix: Mouse digit select, on VFOA & B (because I had enlarged the VFO numbers previously)
11/25/16 T11: Add: TUN button: Right Click to toggle TUNE button between TUN = Standard continuous wave TONE, and TUNs = Pulser TUNE mode. Go to Setup->Transmit and select pulses/second and duty cycle of pulser. Not as precise as using the cwx, but doesnt require a mode change.

DRIVE Level Lock:  Right Click on DRIVE: text (just above the drive power level slider) to LOCK = RED or UNLOCK = WHITE Drive level (as well as the TUNE drive level).  Be sure to preset the drive levels for each band before locking. It will not prevent the levels from changing when you change bands.

11/23/16 T11: Add: HttpServer Advanced Mode allows Frequency, Band, Mode, Filter remote selection as well as Pan display, brought to you by Nick RN3KK (note: this is currently not password protected)

11/22/16 T11: Fix: VOACAP map. was using wrong S unit scale (dBM, but voacap is dBW). Also map changes with Mode: CW vs SSB vs AM, because CW requires less signal strength for a contact.

11/18/16 T11: Fix: Voacap crashing below 1mhz and also not updating immediatly with direct freq entry or swl list selection
Fix: When in MUTs AF slider not adjusting volume for your Headphones.
11/16/16 T11: Add: Watts slider for VOACAP (adjustable from 1watt to 1500watts)

11/15/16 T11: Fix WWV time decoder not reset filter back to original size when decode ends.
11/15/16 T11: MUT button:  Right mouse click on MUT button to toggle between Muting all sources or Muting just the speaker (not the headphones, and not VAC1). “MUT” = standard mute, “MUTs” = mute speaker only.

11/15/16 T11 Fix: fix VOACAP not reading frequency correctly for certain "regions". Fix: Voacap using SFI based SSNf, with TX power reductions based on value of K index. Add: Beam ant option to voacap vs dipole

YouTube Video Describing RevT11 (VOACAP):

11/14/16 T11 Add: VOACAP Propagation prediction from your transmitter location: Using Date, Time, SunSpot#, Frequency, and selecting your Lat & Long location using a Dipole @ 1500 watts, a SdB propagation map is created and presented onto the “Track”ing World Map. Dots represent the Signal strength of a person at that location (around the Dot) trying to Receive your Transmission. Small Gray Dot=S1-S2. Small Orange Dot=S3-S4, Med Yellow Dot=S5-S6, Large Green Dot = S7-S8, Large Gray Dot = S9-S9+. The SunSpot# will only work when you activate the PowerSDR console Space Weather (lower Left side of screen). Might try converting Dots to Contour lines?. I install a seperate copy of Greg Hand's compiled version of NTIA's / ITS Voacap Fortran program. Works up to 30mhz.
Added a Red Star to indicate your Stations Location on the world map, based on your given Lat and Long values.

11/11/16 T11: Fix: Grayline issue. Update SWL file (from
11/08/16 T11: Fix: WWV Radio Time/Date Decoding now working for Flex-1500 as well as 3000, and 5000

11/07/16 T11: Add: Griffin PowerMate USB Knob: Now can have its own adjustable tune step rate (apart from the MouseWheel and keyboard). setup->General->User Interface->Independent. Updates to SWL and SWL2 files

11/06/16 T11: Fix: Added "Day of year" to WWV decoder reception. This is required to get the Date correct when the time is updated to your PC.
Fixed "Beacon chk" and "Time Sync" not allowing dx spotting to reappear back in the spotter windows when you turn the "Beacon chk" back off, or as soon as "Time Sync" is done.
11/05/16 T11: Fix Time Sync Internet NIST locking up on a failed connection.

11/02/16 T11: Added simple Goertzel Tone detection to WWV time decoder (provides better S/N ratio). Only issue is 100 hz required sample time needs to be a little longer than a 2048 192k SR, so automatically set SR to 96k during WWV time decoding. Frequency, Filter, SR, Buffer parameters are saved during the decode and restored after the decode is done. NOTE: PowerSDR must be running in ADMIN mode to allow PC time to update.

Youtube Video describing the Time Sync Function:

To update your PC time using Radio WWV time: Check "Use WWV HF" box and click "Time Sync" button and watch the Spotter window for the decoding process. This can take up to 1.5 minutes, if you just missed the start of the last minute. Watch the "Tone" indicator to make sure it is following what you are hearing as far as the Ticking sound of WWV. If the Tone indicator is not following, then the Signal strength of the sub-carrier is too weak, signals are fading, or a storm is disrupting.

To update your PC time using Internet NIST: just click on the "Time Sync" button (without the "Use WWV HF" checkbox). Decoding process takes milliseconds.

Fixed: Upated to latest SWL.csv file and Fixed another SWL display and listing issue.
Fixed: Full duplex with TX on VFOB keeps the AF slider as AF (except if you have the MON enabled, then the slider changes to the MON AF setting as it should). And now RX1 Mute checkbox works in full duplex with VFOB set to TX.

10/30/16: T11: Started work on my very first decoder. WWV BCD time coded sub-carrier. This current version uses signal strength and simple filters,so it doesnt work well (needs to very strong and clean WWV).

10/25/16 T11: Fix mistakes in the SWL "day & Time" checking. Fix mistakes in the Beacon scanner.

10/22/16: T11: Add: NIST Time Sync Button to Spotter window. NOTE: You must Launch PowerSDR in ADMIN mode in order to allow the "Time Sync" button to update your PC time. To Permanently set ADMIN mode, right click on the T11 Icon then: Properties->Compatibility->"Run this program as an administrator". You must also have Internet to connect to NIST. This is useful for the Beacon Scanner, WSJT & WSPR and any program requiring your PC to have accurate time.
Fix: Save the last Beacon Signal readings, Until you start a new 3min or 15min scan.

Youtube Video describing the Beacon Scanner:

10/20/16 T11: Fix: Can now leave DX spotter running while checking Beacons (it just hides the dx spots, until you switch beacon off)
10/19/16 T11: Improve Fast Beacon Scanner (1.25second per beacon) and map display
10/18/16 T11: Fix Grayline (when entire top artic area stays in dark)
10/16/16 T11: Add Experiment:NCDXF Beacon Scanner:
This feature gives you a direct method of determining radio wave propagation conditions(i.e. band conditions) for the 20m,17m, 15m,12m, and 10m bands. A System of 18 stations, around the world, transmitting (24hrs / day) in 10 second intervals on 5 frequencies (5 separate stations simultaneously) on 14.1mhz, 18.11mhz, 21.15mhz, 24.93mhz, and 28.2mhz. (Repeating every 3 minutes).Your PC clock must be accurately set to make sure PowerSDR matches up with the Beacon stations.
Under the “Spotter” window is a “Beacon Chk” button with Fast & Slow Scan options. You will see a list of Beacon stations (upper left corner) and the current 5 stations transmitting). With “Map Calls” checked, you will see all 18 stations (and each of their 5 frequencies).

Slow Scan: Starts on 14.1mhz beacon and listens for 3minutes (1 complete loop) for 18 stations and records their signal strength, then moves to 18.11mhz, and so on, until 28.2mhz. 15 minutes total time. You can select the starting band 1 through 5. 1=14.1mhz up to 5=28.2mhz
Fast Scan: Scans through all 5 Beacon frequencies (1 second per beacon) in a single 10 second interval, and records the signal strength on each frequency. It repeats this quick 5 frequency scan 18 times to get a complete Beacon map in 3 minutes, but is not as accurate as the Slow Scan.

You might notice a startup lag (of up to 10 seconds) because PowerSDR needs to be in perfect sync with the Beacon stations.

Colors On the World Map
: Gray = Not scanned yet. Violet = Currently Scanning, Red = Not detected, Yellow=Not detected/Weak, Orange=Light, Green=Strong.
On the SPOTTER window: All 18 stations x 5 frequencies are listed (total of 90 entries)
As the stations and frequencies are scanned, signal data is added to the SPOTTER entries.
-NA dBm = Not Scanned yet.  S9 -018dBm = S9 signal level, but only -18 dBm above the noise level.

At the Start of any Scan, the Mode is changed to CWU with filters set to 550hz - 650hz. This is to try and eliminate extraneous noise.  Prior operating Mode and Filter High/Low settings are restored when the scan is finished.

See for further details

10/12/16 T10: Fixed SWL/SWL2 merge mistake. Updated SWL.csv file and SWL2.csv files adding HFDL, ALE, DSC, Maritime channels, and NXDXF Beacons to the list.
10/11/16 T10: Add: Automatic Antenna Control: Setup->CAT Control->Enable Rotor. You must select 1 side of a virtual COM port pair. The other side of the COM pair connects to DDUtil. DDUtil will automatically convert the beam heading into the proper format for your Rotor control.
Left Click on the BEAM HEADING of a DX spot in the Spotter window to Move Antenna
OR, Left Click on the Right Side of a DX Spot + CTRL Key in the Panadapter to Move Antenna

10/08/16 T10: Fix: SWL daysofweek mistake
10/07/16 T10: Add: Http Server now streams live Display with no special commands or special setup. Setup->User Interface->Active. Open your web browser to http://localhost:8081/ to stream Display. Refresh rate sets the update time in msec. Still experimenting. Thanks to help from Nicholas RN3KK 10/06/16 T10: More fixes to SWL Spotter to reduce clutter.
10/05/16 T10: Fix: SWL Spotter now looks at DayofWeek to remove duplicate spot on panadapter display.
10/03/16 T10: Fix: Mininum size for windows (like the Memory or Spotter windows) no longer 0, so they wont disappear on you.
Fix: HttpServer no longer requires anything special (other than a "Port Forward" in your router only if you want outside access). Thanks to help from Nicholas RN3KK (user name and password not active at the moment). If the Httpserer checkbox is active, use: http://localhost:8081/image

10/02/16 T10: Add: if Wave->"QuickAudio Save Folder" box is checked,MP3 Quickaudio files now goes into QuickAudioMP3 folder instead of the QuickAudio folder (which contains just WAV files).
Fix: MP3 option (both Schedule and QuickAudio) set Wave to POST 48kSR during recording, and set back to original settings when done with recording.
Fix: Flex Temp & Volts now in its own thread.

10/01/16 T10: Add: MP3 option (Wave->QuickAudio CreateMP3 checkbox) to save an MP3 of each QuickAudio file (makes it easy to message or email your friends a copy of their audio recording)

09/29/16 T10: Fix Allow FlexControl to run VFOA slider.
09/28/16 T10: Experimenting Add: HttpServer. Setup->General->User Interface->HttpServer. Setup Port# and UserName and Password.
Example: If you use Port 8081 and want to remotely access, you must "port forward" port 8081 to your PC running PowerSDR.
Now you can use a web browser to view the PowerSDR Display window. http://localhost:8081/image Hit F5 to refresh for now.

09/27/16 T10: Fix: SWL listing screen, now that the list is larger. Fix: forgot to include dll's in installer for the mp3 creation. Fix scheduler mistake (losing data)

09/26/16 T10: Add: SWL2.csv short wave listing file. This gives the ability to add SWL or Utility frequecies not in the SWL.csv file provided by For this first round I have added HFDL digital frequecies. Download the free PC-HFDL to decode the data streams. PowerSDR stitches the SWL.csv and SWL2.csv file together when you activate the SWL spotter.

Email me and let me know of any SWL or HF Utility frequencies not found in the current list, and I can add them.
Between the SWL.csv and the new SWL2.csv files PowerSDR T10 will have a more complete list of signals outside the Ham bands (even if many signals cannot be decoded unless your part of the government).

YouTube Video Describing RevT10 (Beam Heading):

09/25/16 T10: Add: Beam Heading added to both Spotter window and Tracking Screen. Put in your Lat/Long into the boxes next to your callsign on the Spotter screen.

When Tracker is enabled: Left Click on Display somewhere and hit SHIFT key to see the Lat/Long grid map to help you determine your Lat/Long. Enlarge VFOA/B even more

09/23/16 T10: Add: MP3 output of scheduler/recorder files. Much more compact file size. Easier to email or IM to someone. Still uses WAV for all other recordings (the standard WAVE and QuickAudio files)
09/20/16 T10: Add: My first attempt at a Sliding VFOA (i.e. the VFOA slides around a stationary display, instead of the normal display sliding under the VFOA bandpass ). Left Click the "PAN:" text button to activate (turns Red). Works, but needs more work. I am trying not to break anything while adding this feature.

09/14/16 T10: Fix: reduce Scheduler Recording SR down to 48k automatically to reduce .wav file size. Fix issues with clicking on memory column headers or starting with an empty memory file. Fix: If PowerSDR was Stopped when recording started, PowerSDR will Stop again after the recording is done. Now at 48k SR, it will be around 600mb/30minutes of recording. Persistance in clicking temp/volts, space weather, dx spotter NA or exclude NA. Working on adding an MP3 output to save more space.

YouTube Video Describing RevT10 (Scheduler):

09/12/16 T10: Add: Memory Event Scheduler / Recorder (modifies your memory.xml file by adding Memory/Frequency Scheduling, but makes a mem.bak backup first).

Fix: Darkened the night area more

03/29/16 S3: Add: Sun Tracker when using the "KE9NS6_World skin" (download from this page below) and only when the DX Spotter is ON. World skin I Photoshopped is a Robinson Projection that I darkened to allow for easier viewing of the Panadapter, however I scrunched it (vertically) to properly fit the Panadapter proportions. Lat and Long lines are all 15° spaced. The Sun image is embeded in PowerSDR and should track Lat based on the Day of the year and Long based on UTC (Right side is 2359 UTC , Left side is 0 UTC, Center is 1200 UTC). I will try to add Grayline. Work in Progress. If you resize PowerSDR window, it could take up to a minute before it does its next update and moves to the correct position on the map. I may need to change the map projection to make grayline easier. Received some Grayline help from Dick W3WVG and Roland Leigh
Fix: try to fix catching QSX or QRX splits

03/27/16 S2: Add: Adjustable TNF notch width (right click on TNF). Was 100hz. Now you can set up to 600hz. Instead of creating multiple TNFs to cover up a noise.
Also, Factory Resets for NR and ANF settings.

Add: Smother Dx window update screen.
Add: Pause dx window button

YouTube Video Describing RevR12 to R1:

03/11/16 R12: Fix DX spotter timeout routine (was timing out wrong spots). Add more Right Click functions for the RX/TX EQ, NB,NR,ANL
03/22/16 R11: Fix Fix Grid display for over 50mhz. Fix Spotter issue after adding <> around Spotter
03/21/16 R11: Add SWL Spot hyperlinking to Google. Click on SWL Spot and hit the CTRL key to open up Google to search the SWL spot.

YouTube Video Describing RevR10:

03/21/16 R10: Add: QRZ hyperlinking on DX spot on Panadapter (Click on the Call sign, then hit the CTRL button, or Hold CTRL + Right Click together). Add: Press Shift key to Show Spotters on Panadapter (toggle), release to go back to DX Spots
Fixed DX spotting (multiband issue). Add "Keep on top" to Spotter and Scanner forms. Fix dx spots correct freq on fractional khz. Change AF to MON when transmitting to make it clear the function of the slider has changed during transmit.

03/19/16 R9: Add: Right click on Transmit profile to open up Setup->Transmit panel
Add: Click on RX1 or TX or RX2 antenna display to open up Antenna panel
Starting to add a Band scanner. Uses Band you are currently on and starts with Default band edges, but you can override them. Stops when reaches High end or signal > Squelch slider level (squelch does not need to be on). Fast scanning wont catch signals. need to keep it slow.
Work in progress. I want to use the waterfall history to detect signals to stop at instead of the squelch level.

03/17/16 R8: Add: Left click on any DX Spot in the text window and go to that frequency directly. Note use the top of your cursor as the point to the spot, I need to reduce the cursor size)
Add: Right Click on VAC buttons to open up VAC panel directly, and auto focus on I/Q checkbox [hit space bar to toggle on/off].
Redo socket stream reader. Fix DX spot text window not removing dups.

03/17/16R7: Hopefully Fix correct reading TCPIP and Text file for Regional/Culture differences. Learn something new everyday.

03/16/16 R7: Add DX Spotting to RX2 as well as RX. Now you can click on the DX cluster status line "Spotting" to check if you still have a live connection. Fix mistake in exclude NA spotters. Add Grid square just below call sign for spots > 50mhz. Any Exception Faults will show up in the text window for diagnostics. Fix mistake that dropped first DX Spot when the 2nd was received.

YouTube Video Describing RevR6:

03/15/16 R6: Fixed the CPU loading even after the SWL spotter finishes loading all 12k spots. A loose "Thread". No longer need the DX cluster name and dont need to worry if the Echo is on/off. Will show DX spots on 6m and Vhf and Uhf

03/15/16 R5: working on reducing the cpu load for the SWL spotter routine. Turn off SWL spot when transmitting. Turn off SWL spots over 30mhz. Its a work in progress. Note: currently DX cluster must have echo turned on to work.

03/13/16 R4: Add SWL Spotter using the CSV file downloaded from Rename the CSV file to: SWL.csv
(Please: If you like this feature you should consider a donation to eibi for the work creating this database file.)
SWL Spotter Still needs tweeking, but it works. SWL.csv file is 12000 SWL records so it takes a while to read into memory, but it starts at 16khz and works up HF band, so the Panadapter will instantly show SWL spots that are on, and fills up the Panadapter starts in the LW and working up to 30mhz. It can take 1min to fully load. But many SWL stations are beaming to other parts of the world (this list has that information) so I need a way to remove spots that cannot be heard at your location.

YouTube Video Describing RevR3 to P3:

03/13/16 R3: Fix: Dx Spotter, checks for Spot dups (takes last unless same call on different bands then it leaves both), Freq dups (takes last spot), Spot timer (drops spot after 30min from the last spot of that particular station). Draw Vert lines first so Calls go over Vert lines..
Almost finished with SWL spots. Data now loads and is parsed ready to display.

03/12/16 R2: Add: NOT FINISHED: SWL spotter using who provides a SWL database in the form of a CSV datafile. You need to rename it SWL.csv. It checks the UTC time and Freq for a possible match on the Panadapter in the SWL bands. Fix DX dup inband outband. I think I have the DX Cluster formatexception crash under control?

03/11/16 R1: Add Spotter has its own window with spot to enter call sign, DX Spider node name, address, and port#
Newest Spots always remove older Dups in both Frequency and DX call. Added buttons to filter NA Spotters or exclude NA Spotters. Still working
LSB Bands show Spots on Left side of Freq line, USB Bands show Spots on Right side of Freq Line.
Still trying to track down a FormatException error that can make PowerSDR crash (it crashes with causing any problems)

03/11/16 Q9: Fix DX spot is now the DX spot. Fix FILO buffer for 60 spots. Need to see if I can use a ring buffer for this instead?

03/10/16 Q8: Add DX Spots to panadapter (This is a rough working version of what I want it to do.) You can view all the spot from the Scanner button window still. I have a lot to fix, plus I want to add SWL to the spotter list. Currently after 100 spots, it resets the Panadapter but not the Scanner window. I lots of work to do (check for duplicates, call sign collisions on the screen, etc)

For the DX Cluster setup: The best thing to do in HRD (Ham Radio Deluxe) is to make sure your Call sign has logged into 2 different DX Spider nodes at least 1 time.
In HRD select node: & Port 8000 and login at least 1 time.
Now In HRD go to View->DX Cluster->Options->Connections: Select another DX spider node (for example: & Port 7300) and connect to it in HRD and then leave HRD set to that node.
Also, You can also setup both your DX Spider accounts to only show DX Spots that you want to see when your logged in, otherwise you may see many spot you dont want to see.
Now PowerSDR can use the"HB9DVR-9 as its DX spotter and it will not prevent you from using the HRD DX Cluster.

03/08/16 Q7: Add SWL bands to Antenna->Expert, Add: testing DX spotter:
First, your CALL SIGN must be in the ""HB9DVR-9. Google for help.
But beware since I am using the HRD spotter, you cannot have the Spotter open in 2 places at the same time.
Enter your CALL SIGN into Setup->General->Options->Custom Title Text
Click on the Spotter button on the main screen to start the DX spotting.
Next Rev, the Spots will appear on the Panadapter by frequency and I will choose another DX spider.

03/07/16 Q6: Add: Add to Band Stack by <Ctrl> & Right Click on Band Button. Add: See Band stack "Index" and "Total" indicators under tune step.

03/06/16 Q5: Add: Drag/Drop File to Memory (copies the file name and location to memory). Right click to open file.
Add: click on Temp a 2nd time changes Temp C to Temp F
Fix VHF panel and VHF output due to mistake when adding SWL bands

YouTube Video Describing RevQ4 to P3:

03/05/16 Q4: Add: Save and Recall a URL web address from your Memory list.
Save: Select a Memory, now use your mouse to, drag a browser URL address to the Memory window and Drop it anywhere. The URL is now added to the Memory you selected prior.
Recall: Right Click anywhere on the Memory row to open a web browser to the saved URL for that Memory.
You can also Drag/Drop and create a new memory at the same time by Dropping the URL onto the ADD button
Fix: Tweek Signal calibration on TR7 signal meter.

YouTube Video Describing RevQ3 to P3:

03/03/16 Q3: Add: QuickAudio PLAY File selection (if Wave->Quick Audio Save Folder is enabled). After you make at least 1 recording, RIGHT CLICK on the PLAY button and select the file you want to play (Clicking Cancel will set back to normal, playing last recorded file). Then PTT or MOX and LEFT CLICK to PLAY as normal. This way you can quickly make a bunch of recordings and then select any one to play back (easier than going through the Wave menu). Add: Frequency change automatically selects the proper Band button (HAM or SWL)

03/02/16 Q2: Add: QuickAudio Folder option (under Wave menu Item). When checked saves QuickAudio in QuickAudio subfolder and sequentially numbers files. Right Click on REC button to go to main folder. Add: add tooltip SWL data to new SWL bands.

03/01/15 Q1: Add: SWL Bands (under the GEN band button), complete with bandstacking for everyband: LW/MW, 120m, 90m,75m,60m,49m,41m,31m,25m,22m,19m,16m,13m,11m. Auto creates (Copies over your current working database into the new database) a new Database.xml with a RevQ in the name, and leaves your original database.xml file intact, so you can still run the old PowerSDR if needed. GEN SWL BAND buttons and panel, use the VHF BAND buttons and panel .png files.

02/28/16 P10: Continuum Display mode (Peak Power vs time) rx or tx, "Auto Wtr Level" changes to show span (in khz) of display used for Peak power calc. If you click the span khz it will restart the Display. Time stamps update every 5 seconds.

02/26/16 P9: Reduce MON audio level of the TUNE signal in your headphones (AF MON level / 8). Add: Continuum Mode to waterfall (not finished)

02/26/16 P8: Fix mistake in RX2 display (cpu time waster mistake).

02/25/16 P7:Fix TX panadapter min value. Forgot I never added a TX panadapter Low value, just a waterfall TX low value

02/25/16 P6: Fix: MON on/off with quickplay. Add: Toggle to turn on/off Panadapter Grid lines. Add Freq Scanner form page.

02/23/16 P5: Add: MON toggle between MONpr (Pre-Processed monitor) and MONps (Post-Processed monitor) for 3000 and 5000.

02/22/16 P4: Add: MON (pre-processed audio) to AM/FM for Flex1500 only in VAC mode though (not through the PHONES jack on the 1500).

02/20/16: P3: Add: MON (but pre-processed audio instead of post-prosessed) to AM/FM modes for Flex3000 and Flex5000.
Add: turn off DoScope() if your not actually using it to save cpu cycles

The MON is normally turned OFF for AM/FM modes. I enabled it for AM, but the MON output in the speakers, headphones, VAC is modulated AM (to the edge of the passband), this is because MON wants to use post processed audio. I will need to use pre-processed audio for AM/FM mode, so its not the audio you are transmitting, but at least the MON function works now.

YouTube Video Describing RevP2 to A1:

02/18/16 P2: Add: Auto Waterfall Transmit Low level adjustment. Key the radio and Click "Auto Wtr Level" to set Waterfall for transmit input level.
Fix: Waterfall only, not displaying correctly due to addition of avgP, avgB previously. Auto Wtr Level turns off if you just in panadapter mode.

02/18/16 P1: Add: Auto Waterfall Low Level Adjustment. Just click the "Auto Wtr Level" button below the display area.

02/17/16 O9: Fix: Found mistake in Source code when compiled under VS2015 caused the check for atu.dll to fail, so Flex3000 units were using OLD ANT Tuning algorithm. Also Dttsp.dll now is updated to current 2015 v140 toolset, hopefully no issues. I embeded vc_redist_x86 into the DttSP.dll.

02/16/16: Figured out how to compile DttSP.dll under v140 platform toolset. Dumpbin showed v140 requires vc_redist.x86 since DttSP is a 32bit C application. Recompile DttSP.dll under C code generate runtime /MT (instead of /MD) will include all required DLL's

02/15/16 O8: Fix: Add toolTips to TXWaterID and Callsign box. Save the AvgP or AvgB settings in database.
Right Click on Callsign Box to open up Folder where you put your own bitmap files to send to the waterfall.
Right Click on the REC button to open up Folder where you will find SDRQuickAudio.wav files from your REC / PLAY use
Right Click on the your current skin (Setup->Appearance->General->Skins->current skin) to open the Folder to the SKINS
02/14/16 O7: Fix: Prevent (if you accidently hit the TX Waterfall ID with the Radio OFF) keying the Transmitter when the Radio is OFF (sitting idle)

02/13/16 O6: ADD: Flex3000 Now has 192k Sample Rate (you can view around 170khz on the screen at 1 time), in addition to the 10khz wide TX

02/13/16 O5: Fix: TX WaterID Now runs on its own background Thread (see video).Creates file when you change the Callsign text field.

02/12/16 O4: Fix: TX WaterID much faster to create image if running 96k or 192k Sample rates. Fix: Flex Audioplayer has a automatic resampler, but the code to make it work had some missing pieces, fixed the missing pieces, so now 48k waterfall resamples for 96k and 192k SR.

02/12/16 O3: Fix: TX WaterID labels: Creating->Transmit-Tx WaterID. Add Grayscale to database. Database name now: ke9ns1.dat

02/11/16 O2: ADD: Database to save mod settings: Callsign ID, Wide waterfall, etc.

02/11/16 O1: PowerSDR compiled under NET 4.5.2. PowerSDR.exe file slightly larger because Cdecl requires each function to have its own cleanup code. The Downside is that you must also copy over a "PowerSDR.exe.config" file becuase of the old FLEX1500USB.dll. NET 4.5 is supposed to be an improvment over the NET 3.5 PowerSDR was using.

02/11/16 Start learning DttSP: Update C++ code to VS2015 and recompile to SDK 8.1, which causes struct redef caused by time.h using timespec and pthread.h using the same timespec,but tv_sec is declared long instead of time_t, so I turned off the pthread.h version for now.
also determined that not all of the DttSP is here.

Completed full upgrade to NET 4.5 using CallingConvention = CallingConvetion.Cdecl in the DLLImport lines of win32.cs and dttsp.cs. Small change to app.config, set VS2015 to NET4.5 and recompile. (thanks to WA1GON for figuring it out)
But also determined that you need to bring a config file along with the exe file due to an old DLL

02/11/16 N7: Fix KHZ freq entry. Turn off KHZ entry for VHF and above freq on both rx1 and rx2.

02/10/16 N6: Fix: Increase TX Bandwidth on Flex1500 and Flex3000 to 10khz wide.
Fix: Improved Waterfall ID 24bit bitmap transmit. Automatically reduced the TX High filter down to 2.6khz during transmit, then back to its prior value. Still learning Bitmaps, and PCM and the conversion between them.

02/09/16 N5: Add: Waterfall ID will now load standard 24bit bitmap files as well as 8bpp 256 color bitmap files.

02/08/16 N4: Fix: VAC1 will automatically turn off when sending a TX waterfall ID, then back on when done.
Add: Transmit 256 grayscale 8bpp bitmap images.
1) Create a small 8bpp 256 color or grayscale bitmap image around 80w x 60h pixels and call it a short name, for example: test.bmp
2) Place that file in the folder %userprofile%\AppData\Roaming\FlexRadio Systems\PowerSDR v2.7.2\ (where the quickplay audio files go)
3) Change the "callsign" to the name of the file with a . at the end of the name (for example: test. ) and it will load test.bmp from the folder and send it.
Warning: There is no file checking. If you do not follow these instructions, PowerSDR will crash. Your database should survive, as my database did.
I provided a "test.bmp" file to place in the folder mentioned above.

02/08/16 N3: Fix changing LSB/USB needs recreate waterfall ID image

02/07/16 N2: Fix image was 2.4khz but started at 250hz, now starts at 150hz

02/07/16 N1: Feature ADD: First attemp at: WaterFall TX CALLSIGN ID. Click the TX Water ID, and the Radio Transmits your Callsign as a Waterfall image that any SDR with a waterfall can see. You change your callsign from the menu item Callsign. Reduced Bandwidth of transmission.

Code Developed:
Wrote code to convert text string into a bitmap image (grayscale or b/w).
Wrote code to convert bitmap image (from file or memory) to digital PCM (any size and any Sample Rate)
Wrote code to save digital PCM as .wav file (any SR, mono or stereo)
Wrote code to copy digital PCM into Flex Quickplay routine
(only issue is the bitmap to PCM conversion time at 192k SR. Need a way to allow lower SR when operating Flex Radio at 192k SR)

How it works.
1) Type your Callsign into the box Callsign.
2) For TX on VFOA: VAC1 must of OFF, you can use VAC2. You cannot use VAC1 or 2 if you TX on VFOB
3) Click on the TX Water ID button to create and send the Waterfall ID4
4) The 1st time you click, there will be a noticable delay (very long delay at 192000) while the image is created before sending it, you MIC will be ON.
5) Subsequent Clicks on TX Water ID will start instantly (unless you change sample rate or callsign or mode).
6) The audio level can be controlled by going to the WAVE-> TX Gain adjustment.
7) Lower sample rates create the initial image faster, so less delay on the first click.
8) Bandpass is around ~ 2.4khz wide starting at 150 hz
9) If your running 192000 samplerate, you will not see a very clear waterfall image. This is because there are only 4096 point to display around 170khz worth of information (~40hz per pixel). It will still transmit clearly. You can only view waterfall images clearly at 96000 or 48000 sample rates

02/04/16 M10: Fix: I believe the studder in DJ console might be related to the PA temp/volts display which take .05 seconds to read and display. Made the Temp/volts display off by default, click on it to turn it on. It updates with the CPU, so whatever you set as the CPU Meter refresh rate is the refresh rate of the temp/volts when its ON.

02/03/16 M9: ADD: Check box in Setup->Display->Waterfall-> Enable Wider Waterfall. When checked this Increases waterfall bitmap size by factor of x2. By widening the waterfall left/right, you must go further up or down frequency to hit the edge of the bitmap. Hitting the edge causes a need to refresh the bitmap (which causes the deley ). The standard moving waterfall draw take ~.015 seconds, the wider waterfall takes ~.022 seconds. Older computers may by laggy with the wider waterfall area. Recompiled under VS2015 UPDATE 1. Font: Found somehow all console fonts got changed to MS SanSerif "Oblique". Trying to change back to "Regular". Swis721 is only for on the Meters.

02/02/16 M8: Feature ADD: On TX readjusts Panadapter Grid to span -90 to 0db, on RX Grid resets back to Low/High settings.

02/02/16 M7: Feature ADD: "Avg" button in Panafall affects Pan & Water. Now you can toggle have Avg Both, or Avg Pan
fixed waterfall issue on resize of powerSDR window.

02/01/16 M6: Fix waterfall move on RX2.

01/31/16 M5: Fix clicking on meter now saves that meter for the next powerup. And learning some of the moving parts.

01/30/16 M4: Fix Flex mistake setting RX2 preamp offset to +14 (sometimes) when it should be -14 (just like RX1 on high mode).

01/30/16 M3: correct crashing issues caused by me going between VS2010 and VS2015.

01/29/16 M1: Fix blank space at bottom of screen caused by not copying the embedded font into the output directory

01/29/16 M: Feature ADD: DJ console

01/29/16 L8: Fixed Emedded Font compatibility issues with Win7 computers. (had to do with multiple fonts and not writing them properly into the privatefontcollection.

01/28/16:L : Feature Add: Freq Entry in KHZ or MHZ. (720 = .720 mhz) (7123 = 7.123 mhz)

01/28/16:K10: Fix: Digital display above meters, shift left 1 space for new font. Put Rev history in the About panel

01/27/16 K9: Fix: embedded the standard Windows Swis721 Font series into PowerSDR.exe. Enlarged the Edge type meter face.

01/27/16 K8: Feature Add: click on RX1 meter to change meter style. Fix edge meter size changing.

01/26/16 K7: Fix:RX2 low level band dBm following what you saved for the RX1 low level band dBm

01/26/16 K6: Fix:Edge meter red number too large.

01/26/16 K5: Fix:High level on TX Waterfall automatically sets to 0 db (you set the TX Low), since 0db is what your trying for anyway.

01/26/16 K4: Fix:Clean out areas of waterfall bitmap no or bad data.

01/26/16 K3: Fix:Turn off temp/volt on Flex 1500. Sometimes waterfall didnt move correctly due to timing issues between freq change and bitmap creation

01/25/16 K1: Added ATU.DLL to resources. This should fix Flex3000 ATU not showing up.

01/24/16 K: Now the entire Waterfall for both RX1 and RX2 moves with the spectrum of the panadapter. This leaves gaps on the left/right as you scroll since there is no data in those areas, but the waterfall will fill them in. This feature is not perfect, If you change ZOOM levels, it will not follow.

01/24/16 J: Add temp and volts to main screen, it updates along with the CPU% (hopefully calling FWC wont mess anything up?). Corrected the POWER on the TR7 meter by modifying the alg. Corrected the text and numbers on the Analog meter. Changed the FONT from the bla "Arial" and "MS Sans Serif" to the nicer "Swis721 BT" (italic). This I believe is the exact Font used by Icom on their displays.

01/23/1 I: Add Signal Peak hold meter for RX1 and RX2 meters (2nd red hold peak line) and db numbers hold peak with 2nd needle. Also corrected S9 readings for > 30 mhz to -93dbm

01/21/16 H: Add Menu item on the top line of PowerSDR for toggling Grayscale and Color for waterfall. Found Grayscale cuts the bandwidth down needed for remote operation. Also added toggle on/off fuction to Peak offset, Peak Power, Peak Freq values in lower right corner of display by mouse clicking any of those values. Also added hover tips to them.

01/18/16 G: Fix the RX1 or RX2 waterfall size messing up when you expand or shrink the PowerSDR console size.

01/17/16 G: Clean up and smooth the Analog meter lines (arcs). Now Analog meter movement(s) for everything except RX ADC(s). Renamed Waterfall "Mic Level" to "TX Level" since its not just for the mic input.

01/16/16 F: Fix Flex mistake displaying CW TX spot on both RX1 and RX2, when it should just be RX1 or RX2. Added additional TX meters (i.e. ALC, Mic)

01/15/16 E: Now you can set the Waterfall Low Level for both RX1 and RX2. Now can you can set the Transmit waterfall low level seperately from RX1/RX2. Note that RX2 and Transmit low levels dont save in database like RX1 (until I figure out how the database works), but RX2 does pull the data for the band your on from the RX1 database, so its not a big issue.

01/15/16 D: Added Panafall mode for RX2. RX1 can run Panafall with RX2 in any mode, but RX2 Panafall will not enable unless RX1 is in Panafall as well.

01/14/16 C: fixed turning RX2 on/off causing issue in window display.

01/12/16 C: Worked in the RenderGDIPlus routine: Created/Enabled Panafall on RX1 to stay on with RX2 enabled.

01/10/16 C: Fixed meters not updating with RX1 or RX2 off by using .Invalidate()

01/09/16 B: Fix missing CW panel. Fix button panel spacings between RX1-Band-Mode-Filter-RX2 panels. Added new RX1 meters to RX2.

01/08/16 A: Found way to turn off RX2 for testing Single receiver Flex radios. Corrected display of Flex radios with only 1 receiver.

01/07/16: Initial release: Worked in MultiMeterDisplayMode: Created routine to convert linear Flex "pixel_x" values to Angle 0-180deg. Created routine to convert angle to Radians for graphical display. Removed Flex "Original" bargraph meter, added "Analog TR7" meter movement, and adding 3rd "Analog" mathmatically generated meter.



RF Linearization (please correct me on this, since this is my first thought about a this topic)
It improves the cleanliness of your output signal, so more signals can fit in the same band. It also improves the PA efficiency, so you could push the same PA harder and still maintain a Linear signal, or dont push your PA and save energy.

The Concept. We linearize DC using a "Linear Regulator", the idea being that we set the DC output (Vout), to a level matched by a (Vref) relatively speaking. We just need a circuit fast enough to adjust the Magnitude level of (Vin) to keep up with load variations, temp changes, etc on (Vout). and keep Vout matched to (Vref).
How do we accomplish this: We use an OP-AMP and place a Transitor, large & fast enough to handle the load, into the neg feedack loop of the op-amp. The Feedback sample from (Vout) forces the Op-Amp instantaneously, in the exact opposite direction that it sees the Feeback voltage go. The sum the 2 opposites will "cancel out" and Linearize the DC signal. But we cannot use this on AC since it would remove the AC and leave us DC.

In 50/60hz AC systems (such as your home power outlet), AC "Power Factor Correction" is an attempt at Linearization of the AC signal. So as AC loads change, the AC is "corrected" to keep maximum power transfer (i.e. efficiency). With Line level AC, its all about the compensating the Phase, since the Voltage level is controlled by the Electric Utility.
How do we accomplish this: PFC circuits are normally just Capacitor(s) and/or Inductor(s) to shift the Phase back into alignment.

But, we can also Linearize RF AC, that is keep the output AC signal as pure as the input AC signal. And since the input RF signal is digitally generated in an SDR, its fairly clean to say the least. But with Linearizing RF AC you are trying to correct Phase distortion and maintain magnitude. Non-Linear qualities in the PA will cause a pure input input sine wave to output harmonics of the original sine wave. To remove the non-linearities you "cancel out" the phase differance (I am not talking about the a phase shift which happens when the signal is passed through the PA, but the phase distortion as the signal is generated) present on the output signal. This requires precision in timing of the Feedback signal relative to the input signal. You need something fast and precise enough to handle RF speeds.

The Flex 5000 Transmitter is already clearner than any Analog HF radio, but you could improve its output by taking a small "feedback" signal from the Output of your External Amplifier, and use it to linearize the entire system. But I must assume there are issues of temperature, aging, and timing that mess things up.

How do we accomplish this: First, OpenHPSDR has RF Linearization in software. Using a RF coupler to pickup a small amount of Output RF and feed it back through the 2nd digital receiver. I think timing is key.
It goes something like this: Using I/Qin signals from the original digital RF before the PA, and I/Qout signals from the RF after the PA (using an RF sampler and 2nd receiver), you take the I/Qout signal and rotate the phase 180deg (taking into account the phase shift caused by the PA circuit itself) and sum it to the I/Qin signal, which does a "cancel out" function, generating a new I/Qcompensate signal. But, to account for the phase shift you need to delay the I/Qin to allow a sync up with the I/Qout signal. This new I/Qcompensate signal is applied to the software that generated the orignal I/Qin signal in the first place.
If you dont want to all of this in realtime, you could create a LUT "Look up Table" and store some of the I/Qcompensate values obtained from a test of some kind. But I must assume LUT RF Linearation results wont be as good as realtime RF Linearization since the number of samples you correct, the cleaner the signal.




It turns out the ATU "Antenna Tuner Unit" has its own SWR metering circuit, but so does the Flex itself. This presents a problem. The ATU tunes up and indicates a perfect match, but when you key up the Flex indicates something less than perfect. The ATU has a capacitive adjustment for its SWR circuit, So I am going on the assumption that the Flex SWR was properly calibrated and get the ATU to match the Flex reading. Now both SWR circuits agree after the Tune.

If the ATU just wont match the SWR of the Flex, then the Flex may need a SWR calibration (explained above)


How to configure you Flex when using an AMPLIFIER with its own external Tuner and still use RX2. With an 2x6 antenna switch

If you happen to use an Amplifier (like most) with your flex and more than 1 antenna, it is not possible to use the built in antenna switch.
The best way around an external Amplifier but multiple receivers issue is a SO2R antenna switch (as shown below)
See or

I added a homemade aluminum box and a remote switch head (just 6 3pos SPDT toggle switches)
This allows me to select any of 6 antennas for any of 2 radios. This way RX1/TX on the Flex always goes through the Amplifier no matter which antenna I choose, and RX2 never goes through the amplifier no matter which antenna I choose.
My setup: Ant #1: G5RV, ANT #2: Cushcraft R7, ANT #3: Mosley TA-33 Yagi, ANT#4: Cantenna Dummy Load

Below is a short youtube iphone video I took showing SO2R (Single Operator 2 Radios or 2 Receivers) operation.

Below: RX1 needs to be on ANT3 because RX2 cannot. Plus you can also switch RX2 over to RX1 tap (to share the same antenna). Note the Use RX1 Out to RX1 in Loop is for the External AM broadcast filter.


(FDX) Full Duplex Operation or (SO2R) Single operator with 2 receivers

Because RX1 and RX2 are seperate and independant modules inside the Flex 5000, its easy to do cross-band FDX or SO2R.

Below is a short youtube iphone video I took showing Full Duplex Operation. Do NOT try Full Duplex on the same band. Be careful to test out your setup first at low power to make sure you have good isolation when transmitting. When you are sure that your 2nd receiver is not picking up your Transmitter, then start raising the power.

I have tested this out, and its possible to receive on 20m using RX2 (VFOb) using a Yagi tri-bander, while transmitting 100 watts on 80m using VFOa and a G5RV ant. Both antennas are around 100' apart. I found no change in the noise floor when transmitting. I believe this would work on any band combination as long as you use 2 different antennas and they are spaced far enough apart.

I was also able to receive on 40m (using a R7 vertical) while transmitting on 80m using the G5RV. Both antennas are around 100' apart. But you need to make sure not to overload the 2nd RX if you run any power.

You dont need the SO2R switch (described above) to make this work. The SO2R switch is only needed when you have more than 2 antennas and/or you have an amplifier. You simply to go the Setup Menu and set the proper switches.

Connect 2 antennas to the Flex and set the antenna swtich menu up properly for your configuration.
!!! Receiver2 must have its own antenna for FDX !!!

Go to Settings->General->RX2:
1) Uncheck "Auto Mute RX2 on VFOA on TX"
2) Uncheck "Disconnect RX2 RF Input on TX"
3) if you plan on Transmitting on VFOb (SO2R operation), then Uncheck "Auto Mute RX1 on VFO B TX" as well
!!!! Make absolutely sure to put back the switches on this menu when your done!!!

4) Now select one band for VFOa and a different band for VFOb
5) Test it out at low power to make sure you dont overload RX2 (or RX1 if transmitting on VFOb for SO2R operation)
6) You may see the noise floor go up if your TX and RX frequencies are close

I have not tried FDX on the same band (Flex says its possible on the 6000 series)

I am not sure how to configure logging software for SO2R (Flex has a procedure for the 6700)

!!! Make absolutely sure to put back the switches on this menu when your done !!!



Listen, or Record and playback your Transmit Audio

There are a couple of ways to hear yourself thru the Receiver directly, for TX Audio checks:
(Just remember the PowerSDR [REC] / [PLAY] records only RX1)

First, The [MON] button will let you listen to yourself, but with a slight digital delay, so its not really usable.

1) You can use [WAVE] and [RECORD] your audio (POST audio as it is applied to the PA). [MON] does NOT need to be on. I would keep it off to prevent any echos in the recording.
a) Turn the Power out put to 0, and PTT the Flex.
b) Hit the [RECORD] button in the [WAVE] menu, and talk (make your recording)
c) Hit the [RECORD] button again to end the recording.
d) The %userprofile%\Music\PowerSDR\ folder contains all the recordings made using the [WAVE] button.
e) You can then take the file you just created and rename it SDRQuickAudio.wav and save it in the %userprofile%\AppData\Roaming\FlexRadio Systems\PowerSDR v2.7.2 folder (which is where the [REC] / [PLAY] buttons work.
f) Now you can PTT the Flex and hit the [PLAY] button to play back your clip.

note: if you hit the [REC] button, your audio clip will be overwritten.


2) or You can Leave the Receiver RX1 or RX2 on while you transmit (explained below)

WARNING: DO NOT overload RX2.

Hear Yourself using RX2 (the 2nd receiver):

Go to Settings->General->RX2:
1) Uncheck Auto Mute RX2 on VFOA on TX
2) DONT Uncheck Disconnect RX2 RF input on TX (this will allow you to not worry about the DRIVE level on transmit).
3) Your TX ant should be a Dummy Load.
4) Plug in Headset to the Flex because the RX2 will not shut off when you transmit

I dont believe you can use the built in recorder to record RX2?
I use VAC2 to send the audio to the PC and record it using SpectraPlus


FlexWire IIC Bus

Flexwire I/O connector is a DB-9 female serial type connector wtih pin 3 blocked so you dont try to plug a serial bus into it.

DB-9 connector view from back of radio:
( 6-7-8-9 )
1: Ground
2: Line In
3: Blocked
5: Ground
8: +13.8vdc
9: Line Out

IIC bus uses pin 5,6,7 low speed (100khz) bi-directional synchronous data bus. IIC bus allows multiple devices on the same bus where each device has an address 8 or 16 bit long.

As implemented in the Flex, iIts purpose is to control external devices that are band dependant.

Apparently, only "HerosTechnology" and "UCB" currently use the IIC bus for there own PCB's

<CNTL> + <ALT> + U: "UCB" Universal Control Board Configuration page

This is used in conjunction with the XVTRs menu and the VHF+ button on the main PowerSDR screen
On the XVTR menu enable a item and give it a UCB Line Number. This corresponds to the above screen. You then select which relays activate for each UCB line number. The VHF+ button on the main screen is how you access this new band.

UCB transmits via IIC bus the following 4 sets of 3 bytes:
0x4c, 0x06, 0x00
0x4c, 0x07,0x00
0x4c, 0x02, (low 8bits value of line#)
0x4c, 0x03, (high 8 bits value of current line#)

ZZFY CAT command can be used to send a I2C command (address and 2 bytes of data)

The HERO preselector menu button sends a address = 0x40 with 2 bytes of data representing the Band and Ant selected from that HERO panel.

PowerSDR KE9NS v2.8.0.70 transmits via IIC bus the following 3 byte set:
0x55, byte Band, byte Ant

Band 160m = 1 thru 6m=11, 2m=12
(Flex5000) Ant: 1,2,3

Digital Decoders (with further detail in the next section)
All decoders tested with the Flex unless stated otherwise

Amateur FT8 (using wsjt-x)

NOTE: FT8 has a rather large penalty on your CPU in a crowded band (like 80m and 40m) trying to decode 20 or so signals simultaneously. The more signals to decode, the higher CPU. My old 4 core cpu maxed out at 100% decoding on 40m and running PowerSDR at the same time. I decided to upgrade my desktop motherboard to a 6 core (2 thread / core) and 16gb of DDR4. Now FT8 doesnt cause any troubles.

Weak Signal or Poor band condition, very short QSO, QSL Communications. (good for collecting awards and checking antenna performance). After you make a few contacts go to: and type in your callsign to visually see (on a world map) where your signal is getting out).

WSJT-X (with JTAlert-X for checking QSL information and interfacing with your Logging software) and
FT8 decode signals down -26dBm below the noise in 15sec sequences (up to 13 characters per sequence) with a typical 4 sequences

Use the TIME sync function in PowerSDR to sync your PC clock (must launch PowerSDR in ADMIN mode).
Use vsgMgr, DDUtil, and Virtual Audio Cable to link PowerSDR to wsjt-x
In wsjt-x radio setup use TS-2000 for now and set PowerSDR CAT to allow kenwood commands.

When you see a RED or VIOLET CQ signal appear in the Left "Band Activity" panel, click on it
(Here is the awkward part:As soon as the CQ appears you only have 1-2 seconds to respond, otherwise you must wait for the next 15 second TX interval).
Your Transmit appears in YELLOW on the right "RX Frequency" panel.
If the CQing station decodes your call sign, you will see them calling you as a RED decoded line the the Right "RX Frequency" Panel

wsjt-x will automatically step through the sequences (after you start by clicking on the CQ station) for short QSL exchange (15 seconds per line):
JTAlert-X scans your main logbook and the wsjt-x logbook and automatically adds your contacts to your main logbook.
And, it keeps track of what you need (Zones, States, Countries, Grids, etc.) and alerts you immediately after every "Decode"

Below is (Free) HD AM radio (iBiquity) as it appears in my car (MKZ) from the 0.670khz signal above (the HD circuitry decoding the [2] 5khz digital OFDM sideband signals). The digital signal is compressed using a proprietary version of mpeg-4-ACC, specifically to make sure nobody can legally write software to decode it.
Depending on how many sub-channels, the Digital sound quality can be very good.
Most FM HD stations have 1 or 2 sub-channels in addition to the HD version of the analog signal.
HD Radio is Free, but unfortunately not free to decode. The only decoder I have is built into my car.
FM HD is almost useless (unless your close to the transmitter) because the FCC limits the digital signal to 1 to 4 % of the Analog signal power output.
The HD Radio is designed to fall back to Analog if the digital is lost. The Analog and Digital signals are synchronized perfectly, so its seamless going back/forth. However sub-channels have no fall back.

Using a Preselector on Broadcast Band Interference

Even though the Flex-5000a has 11 sets of 11th order band filters (1 set for every Amateur band), It doesnt have a AM Broadcast band Filter (BC preselector) to really limit 50,000watt energy.
But the Flex does have a RX loop connection on the back, so you can insert external RX filters that wont interfere with transmit. Under ANT you need to check box "Use RX1 Out to RX1 In Loop". You will need (2) double ended BNC coax cables to wire it up to the Flex.
I live 5 miles away from a large clear-channel AM transmitter. Certain times of night it shows up across 160m thru 60m.
My Clifton Labs BC notch type filter completely notches out the AM Broadcast band (S9+40db signals reduced to -120db)

Unfortunately, to use frequencies below the AM Broadcast band you need a different type of filter (low pass) which cuts all energy above 500 khz.

(Shown: Clifton Labs Z10020B notches out 530khz thru 1600khz)
DX Engineering now sells the Z10020
or DLW-FL1718 for a 200w rated inline filter

Receiver Birdies (Panadapter Bridies)

The PowerSDR Panadapter exposes a whole set of new issues to deal with in radio. When you open up the Panfall to 192khz, and adjust the waterfall color levels, you will see many signals across all parts of the HF band. Sometimes issues crop up and you start to see things that dont add up. All Radio's have their Birdies, its just on that on the Flex (with its great sensitivity) its disconserting to see them all at 1 time.

Click to download a copy of "US Navy Noise Handbook"

1) You see spikes appear and dont move as you scroll frequencies.
This could be a software issue in PowerSDR, or your PC or Firewire connection slowing down causing DSP conversion issues. Check PC services running in the background. Reset the software or your entire computer. Or this could be a birdie cause by the DSP hardware/software
2) You see signals across the Panadapter, but upon inspection determine that they are real signals but repeating at intervals across the spectrum.
This is frontend overload. You may need to add a Broadcast band filter to RX1
This can also be Switchmode or IF hash coming from sources all over your house (see below)
3) You see the waterfall noise level changes or jumps.
This could be when you switch between bands, and because your antenna is designed for certain bands, its efficiency on any band will change.
When you leave a Ham band for a General Shortwave band, you dont have the same hardware filtering.
or the PowerSDR or PC has issues and you may need to reset.

Run remote desktop on your Laptop (running on battery) and go around your house and garage. Unplug everything and check the Panadapter.
The worst offender for noise/Birdie issues is the "Switchmode" power supply. Some can be so bad, they can be in your neighbors house.

1) Your Desktop PC switchmode will generate noise: Be carefull when putting the Computer to SLEEP, this can create noise throught the HF band, more than simply turning the PC off or leaving it ON. I think its becuase the PC goes into LOW POWER mode and the switchmode is designed for larger loads.
2) Your Desktop PC CLOCK will generate noise: Check your bios settings for PC CLOCK "SPREAD SPECTRUM" try setting this both ways.
3) Your Laptop inline power supply can be a big noise generator. Sometimes its worse when its plugged in, but your laptop is in lowpower mode.
4) Your Flat Screen TV: unplug it.
5) Light Dimmer
6) Garage Door Opener (the receiver circuit on the opener itself).
7) Your Cordless Drill battery Charger
8) Microwave oven (usually interferes with TV).
9) DSL or UVerse or Cable
10) BPL or HomePlug (Internet data over your home's AC wiring (Dish Network boxes have this feature)

Some of this may be removed by installing a CLAMP-ON Ferrite Bead designed to Choke HF

UK_Plus = UK+ (adds 60m band)
Norway = Norway, Czech Rep.
Slovakia = Slovakia, Malta
IARU3 = China, Australia, New Zealand
Italy_Plus = Italy+ (40m band)
ES_CH_FIN = Spain, Switzerland, Finland
IARU2 = Central & South America

The TURF region determines your Band Privileges (where you can transmit)
The TURF region is programmed into the Radio's EEPROM

Once you update the TURF Region of your Flex Radio, cycle power,
Run PowerSDR setup->General->Options. Click on "Update BandText" button
This will update the "Band Text" that appears just below VFO-A and VFO-B to match your "Region"

NOTE: If you just added 60m band transmit to your Flex and you run into trouble, search this webpage for:
60m update to IARU Region 1

NOTE: Firmware updates provided in PowerSDR software will NOT disable your "Extended" or MARS operation.
So dont worry.


MARS operation (Extended operation)

The Flex-1500, Flex-3000, Flex-5000 can be made to operate in "Extended" or MARS mode.

NOTE: Firmware updates provided in PowerSDR software will NOT disable your "Extended" or MARS operation.
So dont worry.

If your Flex Radio has MARS (Extended) operation enabled, the top line of v2.8 PowerSDR will not only show your TURF Region but also show the word "Extended"

FlexRadio Ver 4.1.3 (in Program Files folder)
Flex-5000 Firmware Ver (under Program Data folder)

Flex 5000 Specs (based on what I can determine):

ARM7TDMI 32bit processor, AD9511 master clock (500 mhz), AD9959 10bit 500msps DDS for generating the LO (seperate outputs for RX and TX), AK53394A 192khz A/D for RX (IF), CS42448 for A/D & D/A audio in/out, 74CBT3253PW used as a digital mixer (1 for TX and 1 for RX).
TX output signal is created by mixing the D/A CS42448 audio thru a 74CBT3253PW mixer with the AD9959 LO
RX input is determined by mixing the AD9959 LO thru a second 74CBT3253PW mixer with the Antenna circuit, then sending the I/Q signals to the AK5394A for 192khz bandwidth

Where the Flex 6000 series and Hermes SDR's use an A/D capable of directly sampling RF energy (so you can view huge sections of RF at one time), the Flex 5000 uses a LO to mix down the RF directly down to a192khz window.
The Flex 6000 series performs DSP Internally, where all other amateur SDR radios require a PC for the DSP.
While the 5000 is no longer state-of-the-art, it still remains a top receiver (see, and is the most flexible ham radio ever.
