[Elecraft] Rig control error with K3S and WSJT-X on 30 meters

[Joe Subich, W4TV]

Band specific problems are nearly always the result of common mode RFI
(RF on the feedline/rig/CAT cable). Start by testing into a dummy load
or with QRP (<5W) output.  After that, use the normal common mode
elimination measures, quality chokes at the antenna feedpoint(s),
bonding all of the equipment together, ferrites on the CAT/USB cable.
