Hi Mark,

I was able to demodulate some of the "weirdnoise.mp3" file with my 
uo11dem program.
The best part of that recording comes out (with some errors) as

?_/W+U*UOSAT-2           0910270065412
20000221003220000230001240006250 07260ZY[mv;V&&&V'~766&7&766

but most of the rest of the recording was more bad characters than good
characters (based on parity bit mismatches).

If anyone has a longer file (preferably as a .WAV file), please email it 
to me.
