Okay so one last question out of curiosity.? Are both voltage regulators regulating correctly? 3.3v and 5v?? Especially at 12v the AMS regulators still make me a little nervous.

yes the TX IO pin dies work under some conditions

Ronald,

On my QDX the TX has never worked and I have not seen any output even in the Tune mode (That was the first transmit I tried to see power output).

Currently, the receiver is pretty deaf, receiving only sometimes on very strong signals and the level indicator for receive in WSJT-X seems to vary between starts.? Sometimes green and OK but most times very low and Red.

I was able to verify audio to the QDX from WSJT-X.? To do so you need to have a terminal program on the same PC as the WSJT-X software and set up the QDX for VOX and radio to NONE.? This allows you to run the Input Analysis function in the QDX terminal.? With that setup, I was able to verify that audio was getting to the QDX.\

As you have observed, the panel light indicates that it is going into transmit mode.

The trace of the TX line is soo thin and in the middle of other very thin runs that I am hesitant on cutting the run to trigger the TX signal with a jumper.

At this point, I guess it is a waiting game for Hans to jump in and help.? I do not believe that I have read where anyone else has the information and tools to dig into the processor and program.

Really disappointed at this time.
