Welcome to the BLACK SWAN 17 Communications Exercise (COMEX). Its purpose is to test the ability for volunteer, NGO, and government agencies to communicate across services in emergency conditions through amateur radio.

The exercise will serve as the annual Simulated Emergency Test (SET) for the Ohio Section of the American Radio Relay League. Controllers will remain active for the first fifteen days of October, allowing any ARES or traffic organization to operate in the period of "intense activity" of October 7-8, or during any other 48-hour period convenient for the organization.
