The SHARES program is charged with promoting interoperability
between High Frequency radio systems used by the Federal departments
and agencies. It is also tasked to foster interoperability through
examination of regulatory, procedural, and technical issues. This
role has taken on added importance with the widespread purchase
and use of Automatic Link Establishment (ALE) technology throughout
the HF radio community. In responding to this role, the NCS
SHARES HF Interoperability Working Group has established the
SHARES Action Item process to identify,
record, and track issues affecting HF radio interoperability in
the Federal government.
Emphasis has also been placed on expanding awareness
of new technologies in HF radio. Technological advancements have
made HF radio more efficient and competitive in day-to-day operations.
Multiple microprocessors, Digital-Signal Processing (DSP) and computer
control, and Automatic Link Establishment (ALE), combine to simplify
and enhance HF radio operation and frequency selection. The US Navy
has successfully demonstrated e-mail links within a surface fleet
Battle Group via HF radio, with transmission speeds of up to 4.8
Automatically combining HF radio and other communications
media such as land line, satellite, and VHF/UHF enables a user to
consider costs and priority in processing messages. This technology
provides selective routing of high-speed, error-free transmission
of fax, e-mail, text, and data files. Data compression techniques
further enhance the effective data rate.
New technologies also enable the transmission of imagery
over HF. High-resolution color and monochrome images from analog
cameras, still video cameras, and digital cameras as well as imagery
from IR and RADAR sources can be processed via HF radio. Image compression
and error correction algorithms are featured in this newly enhanced
The SHARES HF Interoperability Working Group
also sponsors HF technology demonstrations at Federal conferences,
meetings and industry trade shows. To schedule a demonstration,
