Global High Frequency Network operates 24/7 for 500 daysThe Global ALE High Frequency Network (HFN) has become the first network to operate continuously for more than 500 days on all international amateur radio shortwave bands simultaneously. The main purpose of the network is to provide efficient emergency and disaster relief communications to remote areas of the world. Beginning with a core group of 6 North American radio operators in June 2007, HFN rapidly expanded to cover large areas of the planet with 24/7 digital communications. It was designed to be an open framework for amateur radio emergency services of the world to interoperate on high frequency (HF) using the global standard Automatic Link Establishment (ALE) system. Relying on ionospheric radio communications, the system of interconnected HFN base stations scans the radio bands every 10 seconds, from 3.5 Megahertz to 28 Megahertz. Through this net, ham operators stay connected with each other at all hours of the day or night in any mode of operation, and can send internet email or cell phone mobile text messages from the field. All ham operators are encouraged to participate in HFN, especially during ALE On The Air Week (AOTAW) from 7 November through 17 November 2008. The AOTAW event encourages ALE techniques and emergency preparedness. To track the operations of the Global ALE High Frequency Network, please see the HFLINK.NET website for more information.
