This group is the number one resource for everything about the High Frequency Data Link protocol (HFDL aka 'HF ACARS'), which is used to send ACARS-like messages from and to aircraft on shortwave frequencies (2-22 MHz).

HFDL is operated by ARINC as the GLOBALink/HF service, with 16 ground stations spread over the globe. The last ground station became active in May 2019 which was Ground Station ID 10 MUAN - SOUTH KOREA.
