MWARA


MWARA is the term for Major World Air Route Areas, which support HF Radio communications to aircraft outside of VHF range.

All frequencies listed are in KHz (USB mode). Groups of frequencies in one region are often referred to as 'families'.

This will be the new stub page to consolidate MWARA frequencies, assignments, and information for each MWARA area.

For other family frequencies, see the International HF Aero Frequency List (last updated Dec 4 2016)

For worldwide listing by families with maps, see here
