Allocation to services

IARU Spectrum Requirement

The amateur service requires a common worldwide exclusive allocation of at least 300 kHz, and retention of the present additional shared allocations in Regions 2 and 3.


This band is used extensively by radio amateurs for contacts over distances of up to 500 km during the day, and for distances of 2000 km and more at night. In many countries the band is heavily populated by networks of amateur stations providing training for emergency communications during disasters, and is heavily utilised during communications emergencies.
