Reference recent discussion about Opera
es Wspr for long haul DX.
Although these modes have some merit they would be more
vunerable over long distances to QSB and long bursts of QRN and therefore a
decode would be difficult.
QRSS es DFCW would be more suitable because part of the
callsign/information would be readable at some time during the transmission.
I have noticed this on local data transmissions on
500 Khz, no decodes because of QSB or QRN bursts but I can clearly see the trace
and had it been QRSS or DFCW I could easily have had an ID or parts of
the information.
ie
With data modes a DECODE or nothing, with QRSS/DFCW at
least some information.
