Ross,

 Can someone please enlighten me what is the lowest db that WSPR can 
 expect a decode?

Joe Taylor would know, but I believe the limit is -33db.

1840   4 -33   0.4  10.140184  GI8HXY IO64 37-9.5
2002   2 -33   3.0  10.140192  OZ1PIF JO65 25 3.8

The figure represents the signal-to-noise ratio within 2500hz bandwidth 
seen by the sound card.
