Are you  seriously  comparing  a time =20 locked   narrow  frequency   tolerance =20  MFSK    system with one  based = on  =20  a  free running  Manchester  coded    = OOK =20 system , immune  from  Doppler  spread and =  capable=20 of  simultaneous  multi  decodes  =  running =20 on  standard  ham 'wobbly bob'   equipment ?
 
Not  forgetting  the  'wobbly bob'  = system  =20 gives a  average of the  signal  along to the time =20 line  and not a  peak  (inverted) value , so  direct = comparisons  are a  little  misleading  ,  =
 
Just the  same  as  say  'Long'  = means =20 long  in English   and  Dragon  in = Mandarin  and=20 a  English  dragon  breaths  fire  and = the =20 other  one  is  made of  fishes and  brings = good =20 luck ...

Stefan,
 
yes, theoretically JT9-10 should work = down to SNR=20 -37 dB in 2.5 kHz (which would read -41 dB on the Opera scale = ;-)
