In general, Hawaii is a very quiet place.
Most passes of AO-51 fly by with no usage.
Accordingly, signal strength and quality are
usually quite discernable (assuming no
anomalous QRM) when QSOs do occur.
The initial reorientation of AO-51 was very
apparent here. In general, the bird
appeared to have less signal strength and
more fades. It was, SO-50 like.
Since reorientation, it is my impression that
the signal strength has improved significantly
but there remain some fades; especially at
lower elevations.
In discussions with KG6NUB and others,
the feeling is that the bird is still in some
kind of "recovery mode." To me, "51"
now seems like its old "self." Fades are
becoming less prevalent.
Finally, my knowledge regarding orientation,
reliability and stability of OSCAR satellites
is extremely limited. The concept of
"recovery" may not even be applicable.
Perhaps the AO-51 team can
shed some light on the results of the overall
experiment.
73 and Aloha to all.
