Course Description:

In the 100 years since Marconi demonstrated trans-Atlantic communications, high-frequency (HF) radio has matured from a quirky, temperamental medium requiring highly trained operators to a reliable, low-cost, automated technology with global reach. This course was developed to satisfy the need of government and industry worldwide to understand and apply 2G and 3G HF systems, and the exciting new wideband (WBHF) technology for video over HF radio.

The objective of this course is to help military officers, government personnel, and industry managers understand the opportunities and challenges presented by HF radio communications, and the ability of the new generations of HF radio technology to overcome the difficulties and provide reliable, economical, long-range communications.

This course is particularly suited for:

  • US and Allied communications engineers, who will learn how to apply modern high frequency radio technology
  • US and Allied acquisition professionals who must make decisions about HF radio systems
  • Industry salespersons who want to understand the emerging generations of HF radio technology
