Re: Global Satellite Coverage (hawaii?)



Bob,

I will look into getting a Satgate station in Hawaii.
Also, attempting a Hawaii to California contact via ISS
tomorrow at 2302 UTC IF something on ISS is alive!
So far, no signals from ISS...
I have been planning this QSO for over a month now with
Rick WH6FC. I sure HOPE that ISS repeater or packet is alive tomorrow!

There are very FEW passes between Hawaii and Ca. that could work.
ISS is at 2 degrees elevation on both ends. This doesn't happen
very often. That is why I rearranged my work schedule just to
try to make contact tomorrow. I guess if ISS is off the air, I
will not be too surprised, but dissapointed. Might have to wait several 
months before another attempt.

We will see....

73, Scott WA6LIE
