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. 73, Pete N4ZR At 11:49 AM 1/28/2009, Philip Carter wrote: >See if maybe you shorted the protection led. > > > >--- On Wed, 1/28/09, Pete Smith <[email protected]> wrote: > > > From: Pete Smith <[email protected]> > > Subject: [Elecraft] Need Help with XG1 > > To: [email protected] > > Date: Wednesday, January 28, 2009, 11:19 AM > > 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.
