Are we sure that it's receiving on the channel that's selected? If the PLL is not locked, you can still hear noise and maybe channel chatter.

But if the PLL is not locked, this will totally shut down all transmit signals at the transmit-mixer stage.

Pin 1 of the uPD858 PLL chip is the lock detector. Should read zero Volts.
