HF Radio Communications System Design Assessment. Technical Task Report 3.2a. Evaluation of Present HF Equipment.

HF equipment and system design have been largely ignored by the U. S. Army during the past ten years. This was in anticipation of achieving sufficient and effective communication via use of other frequencies and media. It is now apparent that HF is a more viable and useful tool than previously thought and deserves a role in the U. S. Army's communications system. The problem of now re-instituting HF as an integral part of U. S. Army communications is approached in this CORADCOM study as follows: a. Determine the usefulness of present assets. b. Determine what are the available and applicable existing equipments that may be used to augment or replace existing assets in the near-term (1980 - 1985). These equipments having been largely developed by industry for other military and commercial users. c. Define technologies and developing equipments that meet U. S. Army post 1985 requirements in coping with 'real life' environment. d. Investigate specific areas for exploratory research and development for future application. Efforts under this task are directed toward (a) above in which the final results determine the usefulness of present operational HF equipments.
