I supposed in any lengthy marriage a selective ear or a biological mute button, so to speak, becomes inevitable ...or so it would appear with my aging K3, purchased in 2009.
Here are the rather perplexing symptoms: After the K3 has been on a while all signals and noise disappear. The radios shows consistent s1 or 2 white noise. This is true on all bands, all modes and with the preamp, agc, noiseblanker, etc on or off. After turning the radio off for an hour or more, all signals return as normal - only to disappear again after an indeterminate period of time. I'm guessing that there is some failure that is affected by the component in question heating up. I use this radio in receive almost 24/7 monitoring the bands. Perhaps she is just tired of listening for me? ;-) Any ideas what this might be? Stupid operator error is never out of the question around here. I thought I would ask in here before bugging Elecraft service in case I'm missing something easy. TIA Eric KG6MZS www.kg6mzs.com I should add that when I transmit a tone from WJST-X, say, the red light comes on the K3, one bar lights up on the K3's RF meter but no power or SWR is registered on my external meter. So that would seem to eliminate anything disconnected from the rear panel connector via an intermittent connection. If that were the case, I would expect to see a "High SWR" reading before the power folded back.
