Eric,
What 'flavor' (version of Linux are you running?
I am running Ubuntu 8.04 amd64 here.
I run the following:

WSJT - Meteor scatter/EME
xLog - Logging for VHF+ contests
GRIG - Radio control - Icom IC-820/910/275h/575h/1275/375h

How about aiming for maximum receiver noise? That should be even more accurate.

Good Morning John
I use a FT897D for satellite and also a FT817 for Full Duplex operation
I use them together so I can hear myself on the downlink (which is the
proper way to do it).
It receives the satellite fine(both rigs)but I would not consider the Ft897D
a upgrade or vise versa,the best
Sorry the list of rigs should read FT847 not FT897D
sorry about that

Hi Nigel, G8IFF/W8IFF
You are right
Aiming the antenna for maximum receiver Sun noise is the best method
because the antenna pattern can be affected by some squint angle and not
be perfectly aligned with the boom but receiving Noise from the Sun in
2 meters and 70 cm implies a very high antenna
Yes that's a good point, I'm not encouraging anyone to go on their roof at
night, in fact I would heartily discourage it for the sake of safety.
What I intended to mean was, I looked at Polaris at night, got the
difference from the way my house/roof points, then took that protractor up
to the
Hi,
I agree with the comments that high degrees of pointing accuracy are not
required for satellite work.
However, if you are super keen to improve your pointing accuracy then you may
like to consider the modern version of the bore sight method.
A bore sight is basically a length of tube,
I use a plumb bob and plumb line. When north star is first visible, I
use these to determine true north on my horizon. I then create in my
mind a picture of where that point is on the horizon. Then during
daytime, I adjust antenna to point at that point on the horizon. A

I will activate grid DM19 (smack in the middle of NV) on August 17th during
the 2130Z AO27 pass (approximate). (It must be a rare grid because even
WD9EWK says he needs the grid!) There is a ghost town out there that I will
visit on my way to AZ. I'll be on my HT and an ARROW. If you need a

I mean no disrespect, and I'll apologize now if what follows offends you or
anyone. I agree - to a point - about pointing accuracy. Let's face it - of the
three FM satellites currently available to us, SO-50 is the largest target we
have. It is a 35mm (13.78-inch) cube. We're

Mark,
If there are no NH stations that get in touch with you, I live 5 minutes from
the NH border and I can make the trip over the border to help with your WAS.

Hi Tim and the list,
Thanks for the kind comments.
Its not my original idea.
I picked it up years ago, possibly from Amsat-UK's journal OSCAR News, or
possibly eleswhere.
Just happy to pass it on. Someone may find it usefull, or suggest a
better/simpler implimentation of the same basic idea.
To find true north at your QTH:
Go to
http://www.usno.navy.mil/USNO/astronomical-applications/data-services/rs-one-day-us
Enter your nearest city and state into the menu
If you prefer to enter latitude and longitude, or if you are outside of the
USA, go to
Or go to:
http://www.usno.navy.mil/USNO/astronomical-applications/data-services/alt-az-us
enter your location and get the azimuth of the Sun for every 10 minutes so you
do not have to worry as much about clouds or trees, etc.
