Thanks, Don; that may have been the key. Even with all of the connectors tight there could be an intermittent fault in any one of them. There are four connectors and two cables linking the K3 with the amp through the KAT500 tuner, as well as the internal connections in the tuner. It could be that a random movement triggered the intermittency and that reseating them all moved the equivalent of the cat’s whisker back onto the sweet spot of the galena. I may just replace them all – or wait until the problem reappears and then do the Band0 line check to see where the fault lies. Thanks again for your thoughtful help . . .

Make sure the ACC connector on the K3 is tight as well as other end at the KPA500 (AUX cable). If you moved things around on the operating desk, it is possible that you incurred some cable damage - you should be able to do a continuity check on the BAND0 signal line in the cable. 73, Don W3FPR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
