High Frequency (HF) radio is a reliable technology for short, medium, and long-distance communications which does not depend on vulnerable infrastructure such as internet wires or fiber optic cables, microwave relay towers, or satellite communications. There is no cost for unlimited usage of your own HF network or shared government networks. Third-generation Automatic Link Establishment (3G ALE) significantly improves the time for stations to establish contact, and secure digital voice and email options make HF a valuable tool to assure your agency or company has communications when it is needed most. Real-world examples of HF disaster communications on land, sea, and air will be discussed.


* Automatic Link Establishment makes HF radio operation as easy as making a phone call from a smartphone
* Simple antennas can be setup quickly for field response or post-disaster recovery, 12-volt battery power keeps HF radio working even during power outages, and HF radio is inherently interoperable
* Acquisition costs are low, maintenance costs are minimal, and airtime is free
* HF radio is more practical now than ever before
