SHAred RESources (SHARES) High Frequency (HF) Radio Program
The SHAred RESources (SHARES) High Frequency (HF) Radio program, administered by the Department of Homeland Security’s (DHS) National Coordinating Center for Communications (NCC), provides an additional means for users with a national security and emergency preparedness mission to communicate when landline and cellular communications are unavailable. SHARES members use existing HF radio resources to coordinate and transmit messages needed to perform critical functions, including those areas related to leadership, safety, maintenance of law and order, finance, and public health.
