Over a period of time I've noticed an occasional error when transmitting
FT8 on 30 meters with my K3S using WSJT-X. A couple of seconds into a
transmit cycle, WSJT-X will display a "Rig control error" box, and I

Thanks for the help W0VTT, AB7E, & K6MKF. I tried each advice as I received
it and thought I had it fixed until today. I had been switching out
