That is the audio that modulates the transmitter.I checked the AC voltage at the I/P. There were variations of 0 to 2 volts.
The varicaps are fed a variable DC tuning voltage plus very low current AC audio that modulates the DC.i proceeded to check the voltages on the varicaps, i did not find any voltage over there.
