at -20dB the signal is just aubible but still to weak for CW copy.

Rik,

 

Looks like I need   another 3dB  for  100%  decode !

 

fb on the  sound card .. may be a change , that was the same problem  with

wspr  , sample rate not  locked .

 

Q have you  only  2  decodes  ?

 

tnx - G..

Could be a  problem  with the  sound  card  when I tried to  run the  two  modes , , cmsk  lock's to  8KHz and ROS needs  48Khz  , result was , ros  did not decode after the  initial frame  lock .. may of  changed now , the  driver  panel  for the  m-audio card shows the  sample rate

Thanks  Rik

 

That is useful ! .. will  leave it running  for a  while

I was not  sure if the 'repairs' to the  Ae had

reduced the  efficiency , as I used to  be able

to decode via the  delft web-sdr ,in the  day but as yet

no  decodes

nb, you  have  caught the  start and stop  frames
