Ham radio is on the move.
Many hams only have time to play radio while mobile, and similarly, whenever a ham contemplates a long trip, his ham radio is high on the packing list. Two meters is fun, and can bring emergency aid, but it just doesn't provide the nationwide coverage that is needed for the mobile ham traveler far from home, the offshore boater, or first-response teams arriving in a disaster area. The ubiquitous radio that everyone has. There is no tuning or tracking required on the uplink since the Doppler shift on 2m is less than 3 kHz. This is not so easy.
