Ah.. missing is the qsb , to remove sections
of the plot so these must be ground
wave tests :- )
Dear all,
as mentioned some days ago
I generated a whole series of Opera, WSPR
and QRSS3 audio with a known
SNR.
For Opera and WSPR it was
easy to determine
the lowest SNR for a proper
decode. But for QRSS3 it
is much more difficult
as it depends on the operators "sharp
eye". It must be somewhere in the
range of -24 to -28dB SNR (@ 2.5kHz
BW).
Today I did put all the QRSS3
screenshots in this range in a
website, where you can fill
in what you see
(decode) for each screenshot.
I would like to invite all
of you to give it a try
and send me the results (the more entries
the better the statistics).
After some time (Feb
10th) will put
all results into some nice
tables and graphs and make them
available.
Of course no personal
(individual) results will be
published. But based on
the results every participant
(who keeps his
results) can see where he
ends.

Challenge" can be found at http://on7yd.strobbe.eu/QRSS/
