I actually use the sun for aligning the antennas. SatPC32 comes with
a program called SuM, which can point the antennas directly at the sun
(or moon!). To align the antennas, I look at the shadow of the
antennas on the ground, and adjust until the shadow is minimum size.
It's really easy, (and yo
hi, well i will through my $0.2 in, for my home station to get as accurate as i
can,
i listen for a satellite beacon on one of the SSB's set the radio to track and
satpc32 to track,
have a radio or wireless mic and take an ht to the roof with me,when i hear the
cw tone that sounds
ok i am set.
There's also the Heavens Above website, which will tell you exactly when local
Noon is. The Sun will be at 180 degrees Az at that time. The disadvantage of
this is that it will also be high in the sky, reducing accuracy. Unless you're
at a high latitude... Bob wins on this one.

Only if your program is accurate and operating correctly. The Sun is not
a smooth mover, at say Noon, it is not due south in AZ all the time.

The North Star is the best. even tho it itself is a little off from
exactly North also. But less than a degree. About 0.6 degrees or so.
If that isn't accurate enough there are tables you can look up to learn
what we call cumulation of Polaris. This is a time when Polaris (AKA The
North Star)
Hi Bob,
I use the Sun, late in the afternoon. The satellite program tells me where the
Sun should be, and I aim the rotor to match. Then up on the roof I go, to
align the rotor mount so the shadow runs down the beam. Worked quite well for
aiming at AO-40.
Of course in the Pacific Cloudy West,
The sun is probably even better...

You'd think I would have this figured out by now. I never paid very close

What I do ( and I'm not sure I'm right,but seems to work ) is to use the
North star to calibrate. I live at 41.2* latitude, so if I crank my
antennas to 41* elevation and point north 0* azimuth I should be pretty
close. I also live at 1* magnetic declination, not much so I don't worry
much ab
