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

[Frank O'Donnell]

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 
start hearing the rig's modulated audio output on its own speaker. This 
only happens on 30 meters, and not 100% of the time. Over the past day, 
I've done FT8 QSOs normally on various bands, but when I tried 30 meters 
tonight I experienced the above error several times in a row. It's 
occurred over time using various versions of WSJT-X. The computer is a 
Mac running Catalina.

I tried going into WSJT-X preferences and changing Radio > Split 
Operation from "Rig" to "Fake It," but the error persisted.

I can try changing around various parts of the setup (using a Windows 
PC, for example), but first was curious if anyone has seen a 
band-specific error like this.

Thanks,
