For those of you still trying to decide whether or not to come to the AMSAT
Symposium in Orlando, here is some information that may entice you.
We are planning to arrange transportation from the hotel to Skycraft

I use a camera mounted on the support strut of the dish feed. It is pointed at
the center of the dish.
Then I simply point the dish at the sun and make corrections to az and el until
the shadow is exactly in the center of the dish.
Then use those corrections in MacDoppler.
Works great! No risk
If the ARISSat-1 satellite goes into eclipse, and the battery has failed, the
software doesn't get to decide when to shut down. The lights are out with no
power.

This is an update on the ARISSat activities.
We had a telecon with the ARISSat team in Russia. Here is the situation as
described by them. The Russian suit battery that was intended to be used on
ARISSat was used during testing both on the ground and onboard ISS when it
first arrived. When it

To all those speculating on the reason for ARISSat not coming on, I recommend
patience.
We will have a telecon with the Russian ham radio specialist and get the actual
information from him.
As soon as we have real information it will be passed on.
The satellite is very robust and is probably
Let me clarify this battery charging issue for ARISSAT.
The crew has the capability to charge the battery onboard ISS. The battery is a
Russian suit battery. That means they have a certified charger on board.
The system was designed such that it's easy to remove the battery and charge
it. From

ARISSat in it's flight configuration does not have a provision for external
power. During ground testing we have a special cable for external power that
connects where the battery goes but that cable was not planned to be used on
the ISS. There is the capability to remove the battery and
There has been much discussion about the possibility of doing some on orbit
testing of ARISSat-1 while it is still inside the cabin.
That has been proposed and it is being considered. There is no decision as of
this time. This idea has some hurdles to overcome before it is a done deal.

The ARISS VHF/UHF antennas were funded entirely by AMSAT-NA and some
volunteers. Would you you like to join the ranks of those who contributed? If
so you know how to contact Martha.
What are you implying here?
Of course you seemed to miss the part about the V and U antennas and the and
There hasn't been much said on the various news outlets about the
second ISS EVA tomorrow morning at 07:30 AM EST 12:30 UTC. During that
EVA the first task is to install two antennas on the Columbus Module.
One is for an experiment for the European Space Agency and the other
is a dual band
