Stan was referring to Q1 on the front panel board, which is the frequency
counter amplifier, 2N4124.  This could cause the problem as described,
so I would hold off on a wholesale rework of the VFO circuitry until the
frequency counter sensing path is repaired.

The VFO itself may likely be operating properly, but just not being sensed
by the FP-MPU.  In that case, the VFO signal should be able to be heard in a
receiver covering about 2.9 to 3.1 MHz (for 170 kHz VFO span).  Lacking a
receiver, the filter board should be able to be peaked to where static
and signals are heard...one just won't know what the exact frequency is
until FP-Q1 is fixed.
