Ok,
So it's not an amateur sat. It is also not an amateur
experiment,so why is it using amateur frequencies?
I have read and reread the regulations governing the use of amateur
frequencies and all I can find is a vague definition to the effect
that the
knows where he can find keps now. That wasn't what he
wanted to know.
I thought it was an interesting story.

this, but I'm almost certain that re-entry heating is
not caused by friction (well may be 10%). Most reliable sources, NASA
included, attribute re-entry heating to shock wave compression of the
air in front of the descending craft.

The difference is that going up, you are going slowly in the higher density
atmosphere which is continually lessening as you go up letting you go faster

Nigel,
Yes, of course, that's true. A single band repeater is a full duplex
radio.
I don't think their are any Ham radios that operate full duplex in a
single band. Of course, I could easily be wrong. Do you know of any?

There, not their - sheesh
