Don, Switching to the RX antenna has no effect. The only thing that seems to work is a tap on the back of the left side panel, at about the 2d connector. That causes the 2Mhz birdie to return. I've touched up all of the solder joints on the 160M board, and on J14. Maybe K1 is bad, but I'll look again for a bad solder joint before going there.
Thanks again. 73, Jim KO5V -----Original Message----- >From: Don Wilhelm <[email protected]> >Sent: Mar 2, 2019 1:58 PM >To: Jim KO5V <[email protected]>, Elecraft List <[email protected]> >Subject: Re: [Elecraft] K2: Flaky 160M switching > >Jim, > >Replacing K8 is not going to do anything for 160 meters.
