The National Communications System (NCS), in its role
of planning and preparing for national security and emergency preparedness
(NS/EP), has undertaken a number of initiatives to provide communications
to support all hazards situations. One of these initiatives, developed
through the combined efforts of the 23 NCS member organizations,
is the SHAred RESources (SHARES) High Frequency (HF) Radio Program.
The purpose of SHARES is to provide a single, interagency
emergency message handling system by bringing together existing
HF radio resources of Federal, state and industry organizations
when normal communications are destroyed or unavailable for the
transmission of national security and emergency preparedness information.
SHARES further implements Executive Order No. 12472, "Assignment
of National Security and Emergency Preparedness Telecommunications
Functions," dated April 3, 1984.
As of March 2010, over 1340 HF radio stations, representing
101 Federal, state, and industry entities are resource
contributors to the SHARES HF Radio Program. SHARES stations
are located in every state and at 20 overseas locations. One hundred
ninety four emergency planning and response personnel also participate
in SHARES. Over 150 HF frequencies have been authorized for use
in SHARES. A SHARES Bulletin is published periodically to keep members
updated on program activities. SHARES Bulletin 04-14 (March 04),
and previous editions of the bulletin, SHARES Bulletin 01-13 (June
01), SHARES Bulletin 00-12 (April 00), SHARES Bulletin 99-11 (March
99), and SHARES Bulletin 98-10 (May 98) are also available electronically
in PDF format. All of these Bulletins may be viewed by visiting
our Bulletins page.
SHARES provides the Federal community a forum for
addressing issues affecting HF radio interoperability. The SHARES
HF Interoperability Working Group (IWG) , established as a permanent
standing committee under the NCS Council of Representatives, is
responsible for providing guidance and direction for the SHARES
radio network, and for fostering interoperability of Federal HF
radio systems through examination of regulatory, procedural, and
technical issues. The SHARES HF Interoperability
Working Group currently consists of 151 members and 105 participating
entities vice organizations.
Overall support for the SHARES HF Radio Program
is the responsibility of the Manager, National Communications System.
The Chief, Critical Infrastructure Protection Branch, Office of
the Manager, NCS., is responsible for administering the SHARES program.
The Manager, National Coordinating Center
for Telecommunications, is responsible for day to day operations
of SHARES. Further information on SHARES may be obtained from the
