There are only 750 call signs available for temporary use. A special event operation usually commemorates an event which is publicly significant. Ideally, this is a one time, non-recurring celebration, festival, anniversary, holiday, convention, dedication, public demonstration and the like. Special event call signs may not be requested just so that you will be able to have a short call sign during an upcoming amateur radio operating event or contest. A special event call sign coordinator may determine that your planned special event operation is not in keeping with the intent of the Special Event Call Sign System. Coordinators have wide latitude in the acceptance, rejection or cancellation of 1x1 call sign reservations.
