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.
