Mike and David, Thanks for your replies. I transmitted into a dummy load once the radio had recovered. I switched to the antenna and worked a couple of stations without any trouble.
The rig is connected to my Win 10 machine for logging (N3FJP AC log). This computer has been a real challenge since I upgraded it from Win 7 to 10. I can no longer control its desire to automatically update - it has beaten me... There have been some issues with COM port assignments after an update, but I have not seen anything else that that has affected the radio. However, I won't rule that out as a possibility. I'm leaning toward RFI as the cause. I think this was the only setting that changed - but why that one? 73, Jim KO5V ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
