AAARRRRRGGGHHH!
Lost it again. After? reassembling into case I no longer get power out on transmit. Receive works. Voltages on Q15 look correct on receive and transmit. 0.17 A draw on receive jumps to 0.29 on transmit, but no longer goes higher on speaking into mike and 0 RF out on power meter.
I have replaced Q15 and no change. The removed Q15 tests OK by the"Quick and Dirty MOSFET Test" method:

Any suggestions as to what to check next?
