Jesse, In the exciter description paragraph 2.1 TRANSMIT AUDIO CIRCUIT it states, "Exciter audio from the station control module (or test microphone) is applied to audio amplifier Q501, then routed to the clipper/pre-emphasis circuit of Q502 and Q503. etc. etc. It's all there for you to read. I do hope that you have a manual?

Any idea which components in the exciter pre-emphasize the audio?
