Re: Newbie Question(s)



Hi Cliff;

Things that are simple and boring to one individual just might be exciting
and thrilling to another. I am wondering how you became the judge of what
satellite communication  should be? My years of working OSCAR 10 - 13 with a
Ten-Tec 23b with Cushcraft antennas are some of the most enjoyable in my 38
years of amateur radio. By the way, I also enjoyed operating a major packet
BBS for 3 years. If you think any form of satellite operation is simple, you
have not learned the basics of Keplerian elements, doppler shift, satellite
location and hand operation of transmitter and receiver "CB" quality
knowledge required to be proficient in non-automated communication.

By the way, how do you tell the difference between cash register noise and
an unknown high speed multiplexed encripted digital signal?
