Ok Alex
 
Well  Op4   has a  set  limit  = of =20 round  -30 dB  I have  seen  -33 using   = the =20 dongle  sdr
 
OP4H ..  if the  window  was   over = 2  hours=20 , then , I suppose its possible ,   the  problem is  = the  decoder  is  centred on  8 Khz  , = so  =20 would  need  a  bfo  that  could  = off =20 set  8K or  use  SL as a  frequency  translator = ?=20 for  Opera  decode 
 
At  -50 dB  s/n its the  lowest decoding  = data =20 mode  , add  another  bag of  -dB's  with  = Markus's  system , you  could be the  first to  VK = with=20 a  full  decode  hihi
 
But   worth  setting  up  for  = ?

I can give OP4H on 136, but is not sure that somebody will RX me = on the=20 other side of Atlantic now.
Besides, I need to TX at freq 136900 - = 136925 (RX=20 136000 USB dial)
