Tom, I've never heard a problem like this reported on the K1. About the only thing it can be is the 20m hetrodyne crystal (X2) circuit on the filter board. I'd re-heat the solder connections at X2 and at pin 5 of switching relay K2B on the filter board. When your unit is drifting, you can use another receiver to listen to the oscillation of X2 (within a few kHz of 22.000 MHz) to determine that the X2 circuit is the source of the drift. 73, Mike / KK5F _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
