Utility Monitoring

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 distances. 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

For decoding HF digital signals, please see the HF Digital Decoding article.

[edit] Aircraft

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.

• MWARA frequencies - Aircraft use these stations to communicate over water when out of VHF radio range.

• VOLMET Aeronautical stations broadcasting weather worldwide
