Tony -
We heard something intriguing after about 14:43:40 UT as the tracking
said the satellite was on it's way off to the north pole.
The 'chuff-chuff' description reminds me of a sound we seem to hear
quite a lot. Quite often it coincides with a pass, though I think we
hear the same (or very similar) during times when Prospero is over the
horizon.
We are going to try the next pass at ~16:00UT if you want to listen in
again. Our new ploy is to wait for the last most opportune moment to
command, as the power _may_ be at it highest (longest charging of
batteries, potentially). So, we'll do short commanding at above 30o el,
and listen.

Hi Roger
I could hear some "chuff-chuff" noises on the last pass and they show
a related doppler shift (although I am not correcting sufficiently) as
you can see in the attached plot. Maybe its some other noise but you
never know.

Commanding went well, from as far as we could make out. We're not
sure if we're getting anything back, however.
We'll be doing this pass today, hopefully:
