I had a chance to troubleshoot my radio this weekend, but am unable to find TP20 on the board.? I've checked everything but the voltages suggested by Jerry.? Perhaps it is clearly marked, but my 65 year old eyes can't see it.
Also, does anyone have an idea of what could be used for replacing the surface mount diode, D5?? I suspect it is the problem with the unsuppressed carrier.
Thanks,
Karl, W5QJ
