Recorded on 145.825MHz at around 20:57 BST, in IO75ww - I have no idea what it is.
From the way it faded up and down I'd guess it was something in orbit
but I can't figure out what. It's not the ISS, it's not NO-44 - I know a couple of other sats use 145.825MHz but none of them seem to fit the bill either.

Sounds like UO-11 to me. N8UX

I can provide a zipped .wav or a .flac of the original recording if anyone wants to try.
Gordon MM0YEQ
Has anyone decoded any tlm channels (that aren't dead)?

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
r??{6^6vF7&6V'~GFGVF'fF7vCG#+Uj5000146000247000348000C49000D 50000551000452000753000654000155000056000357000258000D59000A 60800E61%FC1620004633341644402651E0C66200267000168000E69000F ?_/W+U*UOSAT-2 0910270065412 000000010001020002030003040004050005060006070007080008090009 10001110000120003130002140005150004160007170006180009190008 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.

Hi Gordon,
... you heard UO-11. The "old lady" is active again since 2 days.

Hi Gordon,
Its good old UO11 - she re-appeared on Sunday according to http://oscar.dcarr.org/ and I heard the signal yesterday morning.
