I had a problem that I remembered reading about on the reflector when I hooked up my new KPA500 to my K3 with PR6/10 preamp using the Elecraft Aux cable and the companion Y cable. I searched the archive and discovered that users found it necessary to remove pin 11 from the cable to the KPA500. The problem I experienced was that the preamp was powered up on all bands not just 6/10/12 meters. I only noticed it when I tried to use my separate receive antenna on 80 and 40 meters. Since the preamp was powered up the RX ANT bypass in the preamp did not function so the K3 never saw my receive only antenna. Removing pin 11 from the Aux cable to the KPA500 solved the problem.
I'm surprised there is no mention of this problem and its solution in the KPA500 manual. I think an alert should be added. 73, Mike K2MK -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA500-Aux-Cable-Pin-11-Problem-with-Preamp-tp7588821.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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]
