Thanks Joe for the update! The higher immunity to certain time delays sounds promising. It is likely that this caused most of the problems. LF! I'm going to run a JT9-10 beacon in the afternoon, star
Hi Graham, of course I would seriously compare modes, based on conveyed bits per transmitted energy, or available radiated power. Of course I'd NEVER EVER dare to compare anything against handmade CW
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 g
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 simultan
carefully levelled steel track Its funny you mention that , as it occurred to me , using one tone as a frequency marker was a bit like a mono rail , but each to his own , as is demonstrated by JR , g
Stefan, I haven't transmitted yet today, and due to the lousy wx the antenna has been retracted to a low position anyway. Well if you can get the rx side to work, I could probably try to connect the

Markus, What about your indoor LF transmit loop?!! :-) 73, Stefan PS: Thanks for the hint about the CW station. I am now listening on the QRG but nothing so far. I would be ready to go in CW on 137.0
Now since 22:10 my antenna is up again, TX running JT9-10 on odd slots, 0.6 W ERP. Will settle on 137424 Hz for a while, ie. 4 Hz above DK7FC. Best 73, Markus (DF6NM) From: [email protected] Marku
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
