Mike... That reminds me. I noticed that too. Whenever I picked up the K1 and sqeezed the bottom it would shift maybe even more than 100Hz.
There was a small double sided sticky tape covered hard rubber piece in my packing material. I never saw what it was for in the instructions or if it even belonged in the K1 kit or not. But I exposed one side of the sticky tape and pressed it onto the bottom cover below the VFO section. Now when I sqeeze the distance between the bottom cover and the PC board doesn't change much at all and the freq shift is reduced dramatically. I just mention that in case others find a 1/2" black square with sticky tape on it in their K1 kits and would like to put it to good use.

The frequency returns to original when the pressure is released on the bottom cover. > > 73, > Mike / KK5F > _______________________________________________ > Elecraft mailing list > Post to: [email protected] > You must be a subscriber to post to the list. > Subscriber Info (Addr.
