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 group. This is also the place to be for logs of stations calling MWARA stations.
The Spectrum Monitor Electronic Magazine is the only remaining hobby level magazine that publishes logs from its subscribers. Most others have gone by the wayside, having been supplanted by many web-based sites - which may or may not have up to date information.
