The purpose of this section is to gather and group HF Utility Monitoring information in a single location. For information on antennas, please see the Antennas Wiki. Our HF Propagation article has links regarding how HF (and higher) signals travel great differences. It's an important topic to understand if you wish to be successful in this game.

The RR forum for this topic can be found here


Aircraft utilize HF communications when VHF (Line of Sight) communications is not sufficient. The primary usage of HF is for Trans-oceanic flights. Trans-oceanic flights communicate with ground stations via HF for position reports and other purposes. Another utilization of HF communications is for HFDL or High Frequency DataLink. Finally Military Aircraft (MILCRAFT) utilize HF for operational and training.
