MF - Medium Frequency - is radio communication on AM-SSB (Amplitude modulation - Single Side Band) in the frequency range 300-3000kHz.
MF is primarily used as a system to communicate between large vessels and coastal radio stations or other land stations.
The range is limited to approx. 300 nautical miles.
Virtually all coastal radio stations worldwide cover MF.
Aasiaat Radio has several remote-controlled medium-wave radio stations in almost all major cities in Greenland.
Aasiaat Radio has also introduced DSC. This has meant the introduction of a GMDSS A2 coverage area for Greenland.
The A2 area broadly covers the coastline from north of Upernavik to the coast north of Tasiilaq at a distance of up to approx. 300 nautical miles from the coast.
