The early K1 units were provided with potentiometers that had a tremendous amount of shaft wobble. Elecraft later went to a pot design that had a much greater amount of shaft support. I had to replace my AF gain pot when it got scratchy in 2001. The replacement was one of the improved versions. I liked it so much that I ordered another and replaced the original RIT pot too. So, I'd suggest ordering two new pots and replacing those in your early K1. >Also, when I press the display button ... the display itself shifts just a bit. This problem comes from less than tight contact of the back four corners of the front panel PCB with the front face of the four aluminum case fastener blocks upon which they rest. This can also cause a "resonance rattle" at certain audio frequencies when using the internal K1 speaker. I solved this problem by putting a small piece of foam tape on the front face of each of the case fasteners. Now the corners of the FP PCB rest firmly against the foam tape covered fasteners, and as a side benefit the front panel push buttons have a much firmer feel because the PCB isn't flexing as the buttons are pushed. You may also need to tighten the screws associated with the front panel PCB standoff spacer. I've not heard anyone complain of this problem in years, so maybe Elecraft started providing something to solve this problem in later production. 73, Mike / KK5F _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
