I wonder if Charly, HS0ZCW ever tried PSK on HF? These are often inaudible
signals barely visible on waterfall with perfect error-free print! WSJT EME
is even better case. Beware of human limitations. Pilots are trained to
fly by instruments!
Absolute limitations on SDR is ADC overflow level which is around 1 mW.
Your contest kW kill them unless good frontend bandpass filters are used.
Fortunately lot of signals are amplitude modulated.
