Mk..
Are you seriously comparing a time
locked narrow frequency tolerance
MFSK system with one based on
a free running Manchester coded OOK
system , immune from Doppler spread and capable
of simultaneous multi decodes running
on standard ham 'wobbly bob' equipment ?
Not forgetting the 'wobbly bob' system
gives a average of the signal along to the time
line and not a peak (inverted) value , so direct
comparisons are a little misleading ,
Just the same as say 'Long' means
long in English and Dragon in Mandarin and
a English dragon breaths fire and the
other one is made of fishes and brings good
luck ...

Stefan,
yes, theoretically JT9-10 should work down to SNR
-37 dB in 2.5 kHz (which would read -41 dB on the Opera scale ;-)
Each of your transmissions has been
decoded here. Are you receiving JT9 as well?

Hi Markus and Michel,
Thanks for the reports :-) Hm, what is the lowest possible SNR in
JT9-10? Guess i'm still 6 dB above the limit for Michel.
I'll continue at
1W TX pwr until 18 UTC, then QRO to give UA0SNV a chance. LF propagation
looks favourable!
