I'm actually going to showcase this also on 80m. why 80m ? 80m is
characterized in the daytime by poor SNR for short <1000km paths but
this mode can showcase just how good it is on vertical incidence paths.
anyone got any good ideas for an 80m freq ?
The mode is about 50Hz wide approx (at the moment- we might double that
speed to reduce TX time BUT increases bandwidth 2x and reduces
sensitivity 3dB) .
The modem can demod multiple simultaneous present users. so a sideband
passband is no big deal. or smaller.
and maybe should start on 40m/30m , because people already have radios
I guess just go in the existing 300 baud APRS freq segments ?
