[1000mp] Carrier on 50.110 +/-

[Tech]

I have just been alerted to  the clock birdie, on 25.055 and
drifting up as it got warmer up to 25.070.  This is, of course, not a
problem on the fundamental, but the second harmonic (50.110 thru 50.140)
is a TREMENDOUS problem when on was trying to use any 6 meter equipment
with the thing turned on.
People have sent rigs back to Yaesu and they found
resonators in their inventory that makes it come out around 25.014, cold, 
which is much less of a problem on 6 meters.

The signal comes from a microprocessor clock @ nominally 25 MHz.  The
real cure would be to use a real quartz AT-cut crystal at 24.995 in this
circuit, but Yaesu cheaped out and used a surface-mount ceramic
resonator instead.

Does anyone know the circuit board and specific location of the resonator 
PLEASE.

As these radios come in second hand there will be issues for owners like me 
who bought in good faith only to find an S9 signal on 12M and 6m drifting 
thru the band.
Any assistance would be appreciated.
