Thanks to all who responded. I was doing the right thing. Another
dilemma was whether to orient the antenna to True North and not make any
corrections in software or set it to Magnetic North and do the
declination adjustment with the rotor software. Six of one, half dozen
of the other. Right now I have it oriented to True North. But, like
Pete said: For the work we do, a few degrees off one way or the other
will not stop the show.
BTW, I have noticed somewhat of a deterioration in the signal strength
of ARISSat-1. I have not been able to copy any of the telemetry for the
past several passes. I have copied a few of the SSTV pix and FM Voice,
but even they seem noisier. Doesn't help that I have a power substation
a few blocks away that obviously needs to have some of the insulators
replaced. I called the power company and asked that they check things
out. We'll see if they respond.
Keep em flyin'

NASA TV WILL BROADCAST SOYUZ LANDING ON SEPT. 15
HOUSTON -- NASA Television will broadcast the return to Earth of three
crew members who have called the International Space Station (ISS)
home for more than five months.
On Sept. 15, Expedition 28 Soyuz Commander Alexander Samokutyaev, NASA
Flight Engineer Ron Garan and off-going station Commander Andrey
Borisenko will undock from the station's Poisk module to return to
Earth in their Soyuz TMA-21 spacecraft.
They are set to land on the southern region steppe of Kazakhstan near
the town of Dzhezkazgan at 11:01 p.m. CDT on Sept. 15 (10:01 a.m.
local time, Sept. 16). Their return was delayed a week due to the

Expedition 29 station Commander Mike Fossum of NASA, Russian Flight
Engineer Sergei Volkov and Japan Aerospace Exploration Agency Flight
Engineer Satoshi Furukawa will remain aboard the complex to conduct
research until their planned return to Earth in mid-November.
The schedule to launch three new Expedition 29 crew members, NASA
Flight Engineer Dan Burbank, Soyuz Commander Anton Shkaplerov and
Russian Flight Engineer Anatoly Ivanishin, is under review as NASA
and its international partners assess the readiness to resume Soyuz
launches.

The AO-27 site has been down for about 2 weeks. I e-mailed Mike Wyrick, but
haven't heard anything back yet.
The Java scheduler app will always be accurate to within 2 minutes (the
cumulative error in the satellite's clock) as long as a new schedule hasn't
been
uploaded to the bird itself. I have also asked Mike to let me know if a new
schedule is uploaded before the website is back up.
Inasmuch as one cannot download the required data files for the Java app until
the website is back up, I have placed the most recent files (May 2011) on the
Java scheduler download page
