HI,

I am having a very weird issue with my radio.

In the past 2 days my radio suddenly stops transmitting during CW or SSB transmittion. I am using ssb or CW, it does not matter and suddently during sending code (both pc generated or paddle) and SSB, the radio will cut the transmit.

I have:

1. updated to the latest ExpertSDR3 software
2. stopped all the other software
3. updated to latest SDC
4. checked all the cables
5. turned off PA just in case
6. added fan so the them is not higher than 36 degrees,
7. rechecked everything

Up until now everything was ok, I was able to call cw/ssb without any issues and the TRCV never cut me off. Never had an issue during contests, I was able to do hundreds of qso's without any problems.

What is going on? Can anyone help? I am not able to make proper contacts now ... getting cut off in the middle of the transmitions :-(

Help please.

I don't know about why it would stop transmitting during CW.
However, I do know that the SunSDR2dx will stop transmitting during SSB if you are talking continuously for more than 5 minutes.

Have been complaining about this problem for over a year. During SSB output just cuts out. This morning, it quit altogether. You can see the audio on the waterfall, but NO output. I can't get it to start again even after a reboot and radio restart.
