SSDR/N1MM-Loss of Bi-directional Communication

W9WLX_Chuck

I’m curious if anyone else has experienced the following issue:

-Smart SDR 3.8.23

-8600

-Win 11 Pro

-N1MM 1.0.10665.0

N1MM and Smart SDR are set up for SO1V operation. CAT control on either TCP or COM port yielded same result. Winkey also set up on COM port.

CAT control works correctly upon initial launch of SSDR and N1MM. Commands can be issues in SSDR or N1MM and both apps communicate bi-directionally unless the BAND selector in SSDR is used. If the BAND selector is used, the communication becomes one way only. Commands issued in N1MM are received correctly by SSDR, but changes made in SSDR do not flow back to N1MM.

I can re-establish bi-directional communications by killing the CAT app, restarting the CAT app, and telling N1MM to retry communication. Again, it will work bi-directionally unless the BAND selector in SSDR is used.
