And that assumes the 50 dB over S9 signal is within the receiver 
passband.  Otherwise the receiver AGC will increase the volume of the 
weak signal to the point where sound card dynamic range is totally not 
an issue.

However, as Jim mentions on his web site, it is important to set audio 
levels so as not to over-drive the sound card input.  And apparently 
with some software it is important to set the sound card to the correct 
sample rate.
