Need help with SO2R setup

[KG2C]

Hi, I could use some help setting up SO2R because nothing I tried worked right for WSJT-X.
I followed the video on SO2R setup with my Flex 5000A which has RX2 installed.
I tried many other configurations in addition to what was shown in the video but no matter what I did, the two instances of WSJT-X did not want to coexist and TX on their VFO without at least one of them getting an error.

Here's my setup running the latest current versions of WSJT-X and PowerSDR:

For completeness, here's my antenna settings as well.

And here's my PowerSDR settings (note that I use pairs 16-17 and 18-19):

The problem I am having is setting up the keying for the second instance of WSJT-X. They both connect via CAT and change frequency on their respective receivers without issue and I have the audio working just fine as well. When I test transmitting on the first instance with the TX icon in PowerSDR on VFO A, I have no problems from either instance of WSJT-X and I can keep using the first to receive and transmit and the second to just listen. Then I try transmitting with the second instance of WSJT-X and I get an error on both instances of WSJT-X whenever the second instance transmits and the TX icon shifts to the second receiver in PowerSDR.
Here's the situation after transmitting on VFO B from the second instance of WSJT-X.

Any help would be appreciated.

I tried different variations of the settings, specifically:
- different handshare for either or both instances of WSJT-X
- different split operation for either or both instances of WSJT-X
- switching to PowerSDR instead of Kenwood for the CAT control
- higher baud rate
- switching off SO2R mode in the PowerSDR antenna settings

In WSJT-X you need to select Split to NONE. Not Fake it. You can go to my website and CTRL F search for: WSJT-X multi-instance operation
It has all the screen shots.

Also just found out that PA19.DLL file in the folder with PowerSDR bad and causing the VAC streams to not function properly.
If your PA19.DLL is from 7/2/2010 that is the bad one. The correct one is from 6/15/2012. I corrected the file in the .328 download

Thanks, Darrin. I have the PA19.dll from 2012.

I actually looked at the screenshots and video while pauing and comparing to make sure it matches what you have.
It is strange that it used to work with Split Operation = "Fake it" and now it doesn't. Both the instruction on your website and the video show it with "Fake it"


If I change it like you said, I no longer get the error message, but I also still don't get automatic TX switching from VFO B back to VFO A when I transmit using the first instance of WSJT-X. The opposite works though, when I TX with the second instance of WSJT-X the TX icon moves as expected from VFO A to VFO B but then it does not ever go back to VFO A.
If I understand correctly the behavior used to be that TX switches to VFO B just while transmitting and it was supposed to go back to VFO A after, but that no longer seems to be the case and it stays on VFO B. Turning off SO2R mode in the antenna settings does not seem to have an impact on that.

I think I disregarded the Split Operation = None configuration because I had the Settings dialogs of both WSJT-X instances opened when testing Split Operation = None and if you switch back and forth between them and pressing Test CAT and Test PTT, eventually they glitch.

Split = none was in an image just under the "WSJT-X SPLIT operation:"
Not sure why Fake it no longer works.
Its been a while since I tried using SO2R with WSJT-X
But I dont recall having the TX go back to VFOA? You would not want that since you need to transmit a few times to complete a QSO?
I think I was just manually going back and forth.
But the best would be when you click on a Callsign you want to make a contact with, the software would just automatically move the TX to that side and make the QSO. So the TX only moves when it needs to move.

Ideally yes, it would switch TX in SO2R mode only when needed. The behavior when the feature was introduced and in the video from 4 years ago was that TX was on VFO A at all times and it switched to VFO B when the second WSJT-X instance was transmitting, then it went back. Now it is not going back and keying the radio from the first instance also does not bring it back.
You can see the old behavior from your video here. The link should start at 3:47 right before you transmit with the second instance.

[ke9ns]

I have updated and fixed the behavior of SO2R with .329.
So now when you connect both instances of WSJT-X (or any SO2R PC program) to PowerSDR, PowerSDR will now change the TX to VFOA or B depending on which CAT port requested the transmit. So now a TX command through the "RX2 VFOB" CAT port will switch TX to VFOB, and all other CAT ports will TX VFOA unless specifically commanded otherwise using CAT commands.

Thank you very much for fixing it Darrin. I can confirm it works as intended now and I am enjoying dual-wielding FT8
