IARU R3 adopts CoA

The International Amateur Radio Union Region 3 Band Plan has been updated to include five emergency Centre of Activity (CoA) frequencies.

These are 3.600, 7.110, 14.300, 18.160 and 21.360 MHz. The move to adopt these frequencies made at the recent IARU Region 3 Conference, follows similar decisions at earlier IARU Region 1 and Region 2 Conferences.

CoA are not spot frequencies, but a starting point + or – 5kHz, are not the only frequencies to be used, and are not mode specific and should be considered as being 'all modes'.

IARU member radio societies in the Asia-Pacific region are expected to take action to include the CoA frequencies in their national band plans to help promote their use for emergency communications and training exercises.
