Re: Emergency Communications



Gopal,
I would like to call your attention to an article in the AMSAT Journal
March/April 1998 Vol. 21, #2. Ron Ross, KE6JAB did a nice job of describing
his trip to the Antarctica, sending many messages and pictures through UO-22
and KO-25 satellites using the digital store forward mode. All operations
were run from a 18 AHr Gel cell including his laptop.
I think we all realize that satellite skills are needed and now, in your
area, is not a good time to be learning .
Most of us over here are wondering how many operators in your area are
capable of using the current LEO's satellites in the digital store forward
mode. This will help us in determining the need for LEO satellite mode
changes to facilitate emergiency traffic during this disaster.
