| Abstract: |
High frequency (HF) communications has been an essential
part of worldwide information transmission since the advent of radio and
has advanced nearly in step with information technology. Today, advanced
thinkers in the field envision HF radio technology as embracing and supporting
such technological advances as HF e-mail and compressed multimedia voice
and data services. A guide has long been needed that brings together
into one concise user's handbook all of the working knowledge of HF Automatic
Link Establishment (ALE) radio technology. Many publications exist
that deal with one or more aspects of this technology-sometimes in great
detail. This guide, which is general in scope, provides a broad approach.
It is a tutorial for explaining the basics of this HF ALE technology and
for passing along working knowledge for hands-on operation of HF ALE systems.
This guide is the product of many authors who have combined their considerable
expertise. |
