When first assembling the RF output connector and the KANT3/KAT3 board, I didn't like the idea of using the long standoff pillar as a "ground" return for large RF currents. The end of the pillar is actually quite close to one of the mounting holes of the SO239, so a much shorter return path can be made by using two solder tags, bent carefully so that they overlap and then soldered together.
If Elecraft could supply a suitably drilled and twisted bit of metal, problems in that upper rear right corner of the K3 might disappear. 73 from Ian GM3SEK >-----Original Message----- >From: elecraft-boun...@mailman.qth.net [mailto:elecraft- >boun...@mailman.qth.net] On Behalf Of Wes Stewart >Sent: 04 March 2013 01:45 >To: Elecraft Reflector >Subject: [Elecraft] K3 Erratic output power > >Has anyone come up with a permanent fix for the erratic output power >problem?
