….thanks to comments and suggestions from K9ZTV and W2CS. My K3 has the Sub Receiver installed, and I have been playing around with diversity reception, using a random wire connected to the sub-receiver antenna input BNC connector. Apparently the carrier operated relay that protects the receiver from overload is being triggered by lots of RF coming into that random wire. When I disconnect the receive antenna, no more clicking. Now that I know what it is, I'll just ignore it. Or maybe someday I'll rig a manual T-R switch arrangement to disconnect the sub receiver antenna except when actually using it.
Thanks, gents! 73 Ray K2HYD ______________________________________________________________ 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]
