I had a similar problem with my XG-2 right after assembly, on one of its three frequencies. Measuring voltages etc. did not give a clue, so I finally took a crystal from my junk box and connected its terminals in parallel with the crystal on the board (simply making the Xtal leads touch the points on the back side of the board). This started full scale oscillation, so I determined the XG-2 crystal in question simply was bad. May have been bad all along or become defective during my assembly.
Elecraft sent me a replacement crystal - which I actually haven't put in yet, but this appeared to be the problem. 73 - Kristinn, TF3KX Pete Smith wrote: > > I have an XG-1 Receiver Test Oscillator which I must have accidentally > zapped with RF somehow (I don't know when) because the output resistors > R6-8 were fried.
