Here's a startling fact — more than 70 Amateur Radio satellites have been launched over four decades. The number is astonishing because these sophisticated and groundbreaking spacecraft are little known outside the ham radio fraternity.

It's membership is composed of volunteer spacecraft designers, builders and operators across America and around the world. READ MORE http://www.spacetoday.org/Satellites/Hamsats/HamsatsBasics.html
