locked K3S and WSJT-X on 160M

Bob McGraw - K4TAX <rmcgraw@...>

I've encountered an issue which I have failed to resolve.    I'm using an Elecraft K3S on 160M.  I have WSJT-X configured to work normally and find that indeed it does for what I'll describe as normal operation.

However, I'm trying to set up to work the JA/s.   To do this I need to transmit on 1.840 and to receive on 1.908.   I have WSJT-X set in the MODE to Data/PKT which does switch the radio to the correct DATA mode.  Then in the Split Operation I have that set to NONE.    Now for the radio I have the VFO A set to 1.908 for receive and VFO B set to 1.840 for transmit.   I have SPLIT manually activated on the radio.  When I initiate and release the PTT on the radio all switches correctly.

Now the issue.  Using WSJT-X v2.1.2 I find that when I initiate TUNE the radio goes into transmit on VFO B at 1.840, there is power out, and it transmits on 1.840.  When I release TUNE the VFO B changes to 1.908.  Thus the next transmission is on 1.908 and is NOT on 1.840 as it should be.

I have tried many options and configurations without success. This includes using Fake It, Rig, None for SPLIT operation with WSJT. The operating system is Windows 10 Pro 64 bit.

From my efforts, it appears that a command is being sent to the radio to make VFO A and VFO B equal upon release of the PTT command from WSJT-X.

Your thoughts and suggestions please.
