My two-year old K3/100 developed an intermittent power problem. At first I had the PA in and out a couple of times thinking it was the reported connector pin problem. No luck. I noted that pushing on the KANT3 board that is used with no ATU would "fix" the problem for a time. "Fix" meaning it would pass TXG on all bands.
To make a long story shorter, I finally called Elecraft support. I was asked to read back the TXGN values and when I did, I was asked how come I had set them to those values. I hadn't knowingly done that but it turns out that when you do the wattmeter calibration, these are the values that get changed. I was instructed to change them back to the default values---with the comment that one should never do the wattmeter calibration. I suggested that if this is the case, maybe the procedure should be removed from the manual. Setting these values back to default (at least the numbers I was instructed to use) and loosening and retightening the screw at the standoff at upper rear corner of the radio fixed the problem.
