Not sure I understand. First, is it an oscillator problem or a calibrator
problem? If you zero the BFO while receiving WWV, does the note change
between AVC and manual (remember full open manual will overload the receiver, so
turn it down)? If not, then probably not a downconversion oscillator problem.
If yes, then one of the downconversion oscillators is being pulled by the
AVC. If, on the other hand, the cal oscillator is changing after zero beating
with WWV, then it must be a cal osc problem. Could be a bad cal crystal or
dirty crystal socket also. Let us know what you try- we'll figure it out,
especially with Roger here.
