-44 . that's  the  Op  reported level ? so  could  be    -50 / -52 in  wspr  levels .. should  be able to  loose  45% , but  don't  forget the  s/n is the  average  over the  time line , so for a full  capture, you  could be  ~~ 10 db over the limit ??
 
Are you  using  a  pre-amp  etc  of just  directly  into the  sound card Ed, ?.  some  questions in the  news  group  over  filters etc , I think  one of the  simple  pre-amps  may  be the  best option ??

OK Graham

Well you wouldn't want to radiate an untidy signal.

Second decode was -44dB, about 10dB / Noise in 46mHz. Signal level varied and about 20% data lost in a block, XYL re arranged the configuration of the dining table antenna, they just don't understand!

Tnx Ed,
 
Steady carrier, that should be  one of the  advantages of Op  on  8Khz , no  real  problems with  sound card 's  and  frequency  stability !
Look's  like  you  may have  some  signals  from PA soon , not  sure  what's happened  to  all the  UK  Tx  stations , I know  there was a  problem  with  having to  inform  the  met-office  ..
