Rich, You have the capacitor mounted correctly, the narrow end is flat while the broad end is rounded. You are also correct to adjust it with a non-metallic tool - both sides of the capacitor are above ground and will be de-tuned if you touch either of the plates.
I suspect your problem is not with the capacitor, but with the bi-filar wound toroid. Check that carefully for the proper leads in the right holes, and make sure the leads are well tinned - you should be able to see a bit of tinned lead above the board - if not, be suspicious of it, even to the point of removing it and re-tinning the leads.. 73, Don W3FPR On 12/30/2010 5:42 PM, Rich NU6T wrote: > I'm in the final stages of testing/adjusting a newly built KAT1 board in > a 2-band K1 (RF Board rev E).
