Default Collins 32V3 Chirp

The 32V transmitters have a silent oscillator... the oscillators
run all the time and are not keyed. Stages downstream of
the oscillators are keyed.

This was to eliminate chirp.

My guess is that some shielding is not working and the chirp
is caused by major feedback. Another possibility would be
the tube that regulates the voltage to the oscillator. Bill Hale K0QA
