Notes:
(1) A good night for tracking but handicapped by equipment problems
which caused me to miss most satellites. The tracking camera was
loosing position and producing a lot of vibration in the images.
The problems were eventually solved by which time there were no
satellites left to track.
(2) The problems were due to the grease becoming too viscous on the
azimuth bearing - probably due to a coolish night and solved by
replacing with a light machine oil, and a broken wire (one of
five ) that drives the elevation stepping motor. Ever tried to
solder a wire in near darkness in a difficult to get position?
Fortunately I was able to keep my muttering at a low level so did
not disturb the neighbourhood except when I barked at some dogs
who cant mind their own business!
Cheers
Greg
