My SunSDR2PRO no longer transmits on the 2 meter band. To be more precise I can hear the carrier / modulation on a separate receiver but the power output is 0W - when I click on Tune the current consumption goes to 3.1Amp

I don't usually use it on 2 meters but wanted to try it our again. Roman seems to think that it is an issue with a relay but I am reluctant to replace it before I have excluded a software issue.

I distinctly remember that it stopped working in one of the Beta versions when version 1.2 was being released and that rolling back to an older version "fimware 41.7?" fixed that. I had not given it too much thought as I assumed that it was a bug and that it would have by now been resolved in v1.3

Two questions/requests

1. does anyone else have a similar issue with their SunSDR2?
2. can anyone share/upload a beta version of 1.2 ? for example ExpertSDR2 1.2 beta_1 ? -

I just want to test my theory before attempting open hart surgery to replace the relay when the issue may still be with software

Many thanks
