AMSAT's third annual CW Activity Day will be held from 0001 to 2400 UTC on January 1, 2019. This year's event is being held in memory of AMSAT past president Bill Tynan, W3XO.
Bill operated primarily SSB, but would always come back to a CW call. Bill's experience reminds us that one need not be a CW specialist to enjoy the mode.
CW Activity Day rules are very simple: there aren't any.
Just operate CW through any amateur radio satellite. Straight keys and "bugs" are encouraged, but not required. The important thing is to get on the air and have fun, as Bill did.
