Title pretty much sums it up. I've traced the audio signal as far down as entering R97, but not hitting the base of Q25. I've got audio signal at the junction of C92 and R97. Then it just disappears.
I've checked R97, it tests good (82 K +/- 10 %). The Q25 transistor tests good. At -50 dBm input the S-meter is showing S9 like it should. Transmit audio looks good on the scope, PA audio works fine. Electrolytics are new (Thanks, Klondike Mike!).
BTW, the schematic in the service...
TRC-459 no receive audio
