Hello John,
What I would prefer to see, is data to include bit error rates (BER) vs.
S/N ratio
under a variety of propagation conditions.
That way I can more objectively determine the better modulation scheme
for an application.
While we can estimate BER with Spectrum Lab by looking at the text
received,
we can not directly tie in a S/N or propagation conditions.
For a block (1 minute) of WSJT JT2 we get reported the signal strength,
doppler, and delta Time.
I would also like to see multiple modulation schemes simultaneously used to
experience a common propagation condition, not with standing anomalous
frequency selective disturbances.
