Some of the noise on the air to ground is due to marginal conditions getting
into the ground stations.  (On the last STS, I could tell how close to
LOS/AOS the shuttle was by the signal/noise ratio on the air to ground).
Some ground stations seem to be very good (TDRS is pretty good, the
Indonesia/Australia ground stations are pretty bad).

A lot of this is due to the telephone links from the remote sites to
Goddard, which are highly variable it seems.
