OK. Bandswitch on 20M, you should have a good strong signal around V1,
Pin 7, at 21.5 MHz.
You should have 16.3 MHz at Pin 6 of V3.

Well, that's a problem!
First thing comes to mind is that the Carrier oscillator isn't
running,
and you are tuning to the second harmonic of the PTO.
On 20M you should have 9.000 MHz from the Car Osc. mixed with the
PTO at
say 5.200 MHz to produce a signal at 14.200 MHz.
You need to see if the 9.000 MHz oscillator is running, on
frequency and
I would expect about 2V p-p across R77 at T13.
