RL801 may not be making good contact. You can check the levels with your scope. I would use SSB and whistle in the Mike for tracing to keep the power dissipation low.

Take a good look at RL801

(PA 1) The RF comes from L305 through HF03 to RL-801 (PA 2) (changes from orange to blue and out through (A). to (PA 3) the bandpass filters. There are a pair of relays that have to be energized for e
