WOLF is a very weak signal mode if both ends are set up correctly. 
Frequency accuracy and stability are important, but so is the sound card 
sample rate. You can "fudge" your way around it in programs like Argo 
and Spectran, but for WOLF, the exact audio frequency and sample rate is 
important. I noticed that the framing values were gradually changing 
during your good run last night. That indicates that the sampling rate 
is different than the nominal 11025 or 8000 Hz. You should consider 
determining actual sampling rate of your sound card. A possible method 
is described at:
