I fiddled around with it a little but no luck. The tones appear to be 220 Hz              
apart, not 850, if the file's WAV header is correct and it's sampled at 16khz.            
The tones seem to be 2228 and 2008 Hz, with the higher one as mark.                       
Even so, I couldn't get minimodem or fldigi to decode it to anything human                
readable either as ascii or baudot with any of the permutations of options I              
could think of... :(
