Okay, so I took the plunge and disconnected the KX3 to take with me on vacation. Hooking it back up proved to be a tad problematic - SWRs of 25:1 and no signals from any bands, anywhere. I'm now working through what options I have, starting with checking female connector deformation and doing what I can to examine oxidation, and general quarrantining of wires and connectors.
I also wrote to Elecraft to get a quote for a replacement BNC connector with the LPF installed - worst case is I'll just start over again with a new chassis connector. Ain't radio fun? :) On Mon, Feb 19, 2018 at 11:54 AM, rich hurd WC3T <[email protected]> wrote: > Hi, > > I had an oddity with hooking an antenna to the BNC connector on my KX3 > that happened enough times to be chalked up to something other than random > chance.
