Numerals serve as shorthand for amateur radio jocks.
The number 73, Kristin explains, means best regards. She recently was selected to represent Colorado and BARC Jr. at Hamvention 2001, a convention for amateur radio enthusiasts in Dayton, Ohio. The event takes place on the last Sunday in August after a hike to the top of one of the state's 54 14,000-foot mountains. Radio hams then set up equipment in a race to see who can connect with the most people at the farthest distances away. This year's event is Aug. 26.
