Description and Links
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.

Digital and Other Modes
HFDL, otherwise known as High Frequency Data Link, or HF ACARS, is now used extensively by many commercial airlines. There is a whole sub-culture of people that use various software packages to copy this mode and track flights which can be found on the Utility DXers Forum Yahoo group. This is also the place to be for logs of stations calling MWARA stations.
