I was thinking about the Russian UVB-76 "The Buzzer" which is still 
broadcasting on 4.625 MC and has been since the 1980's.
 
I was thinking that it would be possible to send a slow data
communications in the buzzing tones similar to a Commodore Cassette format,
with about the same data speed. 
When you listen to a Commodore program on tape the data just sounds like
buzzing unless a number of the same ASCII characters are repeated. With
encryption used the data would sound random.
A Commodore .SEQ file which is much the same as a .TXT file sounds like as
series of buzzes and inter-block tones. 
There have been a number of people that have monitored it and sometimes
there's a voice that come on with a brief code but otherwise it's just
buzzing.
Kind of a long shot but it's possible. 
A simple program on the receiving end that captured the audio and pieced it
back together as a file, and the file sent twice for error checking.
