It is a matter of deciBels as has been documented. Each time a stream is added 
in multi-stream there is a multi-dB power hit on all streams. This is what SF 
avoids but TANSTAAFL. You do lose some sensitivity but at that point you would 
probably not be hearing multi-stream FH either. It seems like you were a victim 
of propagation. If you were copying three streams of FH you probably could have 
copied SF under the same conditions. Just a guess as there are multiple factors 
in play. I was decoding SF more reliably than anything over 2 FH streams. It is 
rare that I am able to copy three or more FH streams when prop is poor. Signals 
have to be very good. That is not the fault of the software, it is the 
limitations imposed by my antenna system and local noise floor vs. propagation 
conditions.
