[Elecraft] Need Help with XG1

[Pete Smith]

Thanks for the idea - I removed both D1 and D2 from the circuit - no 
improvement.  The signal is quite audible (in the 50 uv switch position, 
and barely audible in the 1 uV position, but doesn't move an S-meter that 
was formerly tested with it and registered S9.

Anyone else?  I know that if I had a scope I could measure the p-p voltage 
coming out of the oscillator, but I don't.
