Markers on the Air (MOTA) is an amateur radio program where operators set up portable stations near officially recognized state and national historical markers to activate sites and contact other hobbyists. By combining portable operations with regional history, the initiative turns roadside plaques and historical monuments into an engaging on-the-air chasing experience.
A location qualifies as a valid MOTA site if it is an officially recognized historical marker—defined as a metal plaque, monument, or designated historic medallion erected, approved, or cataloged by an official state historical commission or a recognized national historical registry. To qualify, an activator's portable station must be set up entirely within 100 feet of the marker and complete a minimum of 10 valid QSOs.
