SHARES Frequency List SHARES Frequencies List SHARES HF-SSB Frequencies Emergency Management HF Frequency List


SHARES is a multi-agency system that used frequencies assigned to several different agencies and organizations. It conducts weekly radio check nets every Wednesday at 1600 UTC on 6765 USB, 6845 USB and 6910 USB (and likely other frequencies at other times).

Since these frequencies are of interest to utility monitors and are often heard, I wanted to compile a list of frequencies in use:

All frequencies are "dial frequencies" in USB mode, transmissions made in USB voice and MT63 digital mode. There are apparently other 5 MHz band frequencies in use, including ones that match up with 60 meter amateur band channels. Frequencies with associated notes are frequencies noted in use by myself (confirmed usage and remarks). Note that SHARES does use ALE technology. Most frequencies are in the fixed/mobile bands.

National Communications System (NCS) Shared Resources (SHARES) High Frequency Radio Program - As an additional means of HF communications, Federal agencies may use the Shared Resources (SHARES) HF Radio Program as a means of passing message traffic when their own networks are not available.

Note: While FEMA, the National Communications System (NCS), MARS and other government agencies are heavy users of the SHARES system, FEMA operates several other networks, many using ALE, digital modes and regular USB voice. FEMA is a prolific user of HF for obvious reasons, obviously. See also the SECURE system, which overlaps SECURE in function and scope. Several of the SHARES frequencies are, well, shared...with other government agencies.
