Thanks for posting the recording!
I downloaded your recording and ran it through
my DSP soundcard UO-11 demodulator. Most of the
data in your recording looks like this, although
other sections are quite noisy.
All of the columns of zeros are telemetry channels that have
failed. This agrees with what Clive has previously reported.
Earlier Clive reported:

Last month the clock was about 74 days slow, but it is now
about 81 days off.
In the past UO-11 also used to send stored ASCII bulletins
as well, but I think that capability of the satellite ended
when the spacecraft computer turned off. Anyone know
