The Great and Honorable Leo Society is a group of Alaska amateur radio enthusiasts who operate the low Earth orbiting satellites. However, our interest lies in all space-based communications and many are also members of AMSAT http://www.amsat.org/. Our group charges no dues and elects no officers. Occasionally we do call for papers and present them in conjunction with the groups dining experience (The LEO Lunch).
SETI http://www.SETI.org/ enthusiast are welcomed.
