Re: the question will always be there, LEO or HEO



Hi All,
The best way to get more Amateurs interested in satellites is not to make it
so technical. Challenge operators to do their own Doppler and antenna
pointing corrections. Once doing it by hand you have an understanding of how
it works making the change over to computer controlled antennas and Doppler
corrections an easy step.
If you enjoy the Armstrong method stay with it. Satellites that are strong ,
easy to receive and lend themselves to portable operation at club functions
are the most effective in bring in new Amateurs. Seeing it done with simple
equipment is the best way to do an introduction to satellites.
I got 2 Amateur Operators on Satellite, one is a K6 Call using Amateur TV
and a third is building and antenna. His is a KB6 Call.
HEO or LEO is not as important as how easy is it to find , receive, and
transmit to a given satellite. If you are doing a demonstration it must look
easy! Practice alone first! Experiments with inband transponders and higher
power budgets for future satellites will also help make it easy.
