Hi Bryan
I had a similar thing happen on a QCX mini, the culprit was a burned up Q5...a BS170...
Strangely this started as a reduction in TX power, Q5, shunting the output to ground partially until it fully burnt out whereupon the TX output returned to normal along with a very signal deprived and deaf RX.
Good luck in tracking it down
