Hi Michael.?
?
When I had a blown PA output transistor, my 12v QMX was drawing a little over 200mA on receive/idle mode. So yours is behaving a little differently at 125mA receive current draw.?
?
In my case one of the 4 PA transistors had an internal short from gate to drain. With the display board removed and the QMX powered up, I could feel (and actually see, since I had an infrared camera) one of my 4 PA transistors was getting quite hot during receive, which should not occur.?
?
You may need help from one of the more knowledgeable electronic gurus, like Ludwig, in diagnosing what's going on.?
?
But, if you can detect one of your 4 PA transistors getting warm in receive mode, then it's probably gone bad and needs to be replaced.?
?
This is more of a hit it with a hammer type of diagnosis. You may need more expert help than I can provide.?
