Ah.. missing  is the  qsb  , to  remove  = sections=20 of the  plot  so  these  must  be  ground=20 wave  tests :- )

Dear all,

 

as mentioned some days&= nbsp;ago=20 I generated a whole series of = Opera, WSPR=20 and QRSS3 audio with a known=20 SNR.

For Opera = and WSPR it was=20 easy to determine=20 the lowest SNR for a proper=20 decode. But for QRSS3 it<= A>=20 is much more difficult=20 as it depends on the operators = "sharp=20 eye". It must be somewhere in = the=20 range of -24 to -28dB SNR (@ 2.5kHz=20 BW).

Today I did put all = the QRSS3=20 screenshots in this range in a=20 website, where you can fill=20 in what you see=20 (decode) for each screenshot.

I would like to = invite all=20 of you to give it a try=20 and send me the results (the = more entries=20 the better the statistics).

After some time (Feb=20 10th) will put=20 all results into some nice=20 tables and graphs and make them=20 available.

Of course no personal=20 (individual) results will be=20 published. But based on=20 the results every participant=20 (who keeps his=20 results) can see where he= =20 ends.
