Wow, guys, thank you all for the suggestions of things to check, but still no joy...
Here's your suggestions that I have checked: voltage - 13.6 RX ANT not on I uploaded a couple of old config files - not change Turning RF GAIN fully CCW puts SWR meter at full scale My other K3 hears FB on all the antennas This K3 doesn't have an ATU Switching an antenna in and out makes no apparent difference in received signals No change in BP filters; they have been working fine for long time. I do operate SO2R. The last time radio was working OK was during the NAQP CW contest where I was running 100W. I have operated KW amps in the past on each radio without any front end problems (but there's always the first time, right?). Thanks again for the help 73 - John, W4AU ______________________________________________________________ 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]
