Listened to AO-51 while on the road between Melbourne and 
Adelaide.  Good signals from the bird for the most part, even on the 
mobile.  However, although I heard a station calling CQ, I had a LOT 
of trouble understanding the audio.  The deviation on the downlink 
was way too low for operating in noisy environments (e.g. mobile) or 
with marginal signals.  I can now understand why one user suggested 
in here to use narrow FM mode - that would have done wonders for 
bringing the downlink audio up to scratch.

Unfortunately, I don't have SSB gear in the mobile, so I wasn't able 
to attempt operation, even if I could hear it better.
