[Elecraft] [K3] Looking for WSJT-X Rig Control advice

[Andy Durbin]

CAT allows true rig split or "fake it" modes of WSJT-X.  In either case the modulation frequency is limited to the range 1,500 to 2,000 Hz and any audio harmonics fall outside the TX passband of most transceivers.  CAT and the WSJT-X split modes do not prevent generation of audio harmonics but they do significantly reduce the risk those harmonics will be transmitted.

If you cannot, or will not, use CAT with real or fake split please do not transmit with DF less than 1,500 Hz.   I have far too many FT8 harmonics examples in my "horror signals" library.
