For simplicity when testing on the lower
frequencies use either CW or QRS, modes all radio amateurs can copy, therefore a
bigger audience for reports.
Only a few are equipped for data modes, this limits
the reports.
I have noticed and reported several times that Data
modes do not always decode, although they are perfectly visible and in some
cases audible. Had these signals been keyed CW or QRS then an ID would have
been possible.
Avoid unnecessary multi layers of modulation
except you have a reliable signal path and want to pass large volumes of
traffic, then automated systems are useful.

Subject: LF: WSPR beacon closing
My 137.5kHz WSPR beacon is now closing for the night. I'll put
it on again on Sunday morning and would appreciate any
reports.
Although G3XIZ was able to decode my QRSS3 signal well today
(he got the callsign and QTH locator) , he was unable to even see the WSPR
signal, which was a bit of a surprise.
If QRSS3 was just detectable
I'd have expected copy on WSPR. Am I wrong and does WSPR require several dB
more signal?
