(including 1200/2200Hz) to -x command line argument in Direwolf. This is useful for calibrating FM deviation using a meter, devcal, or manually. See: https://groups.io/g/direwolf/topic/setting_deviation/78633292 Options are: -x a: alternating mark/space tones (original functionality) -x m or -x 1: steady mark tone (e.g. 1200Hz) -x s or -x 2: steady space tone (e.g. 2200Hz) -x p: set PTT only - for RTL-SDR adjustments Scope tested with mark_freq>=300Hz and space_freq<=5000Hz. Returns an error message if mark/space frequencies are set to 0.
