SET is a multi-state radio communications exercise (COMEX) to test the ability for volunteer, non-government organization (NGO), and government agencies to communicate across services in emergency conditions through amateur radio. The Ohio Section of ARRL is coordinating the exercise and will use it as the Ohio Section SET for the year 2017, providing background and superstructure for more complete exercise play, coordinated across county, district, and section boundaries. The Ohio Section will publish templates for participating organizations, including an Exercise Plan (EXPLAN) that implements local operations as part of the larger exercise.
