You are probably hearing the bias switching relay changing the bias.

Commander HF-2500..

Every time the T/R relay goes back to receive, I'm getting a pretty big RF
spike that I can hear in the receiver. This has nothing to do with the
transceiver hot switching or RF stored in the tank circuit. I can reproduce
it just by cycling the T/R relay in the amp with a separate cable, not
connected to the transceiver, and not transmitting.

Suggestions ?
