Need help with SO2R setup
Posted: Tue Apr 21, 2026 3:46 pm
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
