My experience is very similar to Chuck's KE9UW. My less than 2 month old KPA500 was living life merrily and then, for no reason I can determine, caused my RX signals to drop an S unit or more in Oper mode--most noticeably on 80M.
The amp now is at the doctor (aka Elecraft support) awaiting final diagnosis, but the preliminary analysis is that the pin diodes went poof. I hate to go Gus Grissom on this but they "just blew." I had none of the dramatics of hitting the wrong button in N1MM or having the coax drop off just before TX into infinite VSWR--none of that excitement. I wish I had, so I'd know what not to do next time ;-). 73 Paula K9IR -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-KPA500-PIN-Diode-Failure-in-KPA-When-K3-Subrx-Turned-on-During-Xmit-tp7570227p7570238.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
