if someone will digitize the signal at some reasonable data rate and bit 
depth and send me some minutes of data, I'll see if I can code up a 
simple decoder that would run on a low end processor.

It's just BPSK at 1 bit/second, after all.

I maintain that it's the lack of a cheap RF front end that is the sticky 
point.
