[Azden] PCS-3000 TONE

Sure, it's the "blue knob"......

The frequency adjustment point is VR412 and the monitor point is TP406,
which is one end of VR411.

If you want to add the Comm Spec board, you will attach the output to the
same test point.....  however, you will have to disable the internal
generator by removing R536 which is the feed point from the internal
generator.  What I have done is to remove the end of the resistor that
goes to Q436 (74C00) pin 6 and use this as the connection point for the
tone module.  This allows you to present a 10 k ohm impedance to the new
Tone module.

The voice deviation control (VR410) and the PL deviation control (VR411)
are connected together through individual 100 k ohm resistors to the
common modulation point.
