You were probably seeing MFSK, which was designed with very robust Forward
Error Correction (FEC) for DX work, and performs much better than PSK
under
marginal conditions. I have been able to decode MFSK 100% when I could
neither
hear the signal in the noise or see it on the waterfall.
Being very pedantic here, I think you (Steve) mean Olivia with the FEC. MFSK
as implemented in fldigi & other software doesn't use FEC. I agree that MFSK
is excellent.
FWIW there's a new feature in fldigi, MultiPSK & other programs called RSID
where a brief special tone is sent at the start of the transmission, this
tone identifies the mode in use.
