Satellites, anyone?

ham satellite cartoonThrowback Thursday: This is a cartoon I drew some years ago for “Morse Code: The Essential Language,” written by L. Pete Carron Jr., W3DKV, and published by the American Radio Relay League.

What do satellites have to do with CW? Carron wrote at the time that the “low-duty-cycle characteristic of the code makes it especially popular for satellite communication.”

That was in 1986 (the book is now out of print). Who uses satellites now, and how do you use them?
