According to carrier measurements this should be an easy decode at around +3db. More carrier measurements: night signal phase lags daytime by 60 degrees. Night amplitude is about 0.1 fT. The 16K25A 15 char 140 second message should decode at about Eb/N0 +6dB. So far no improvement on the partial decodes, next to try is correcting for that 60 deg diurnal. -- Paul Nicholson -- |
