Other information

Proposed assignments to the HF land mobile service are subject to the notification procedures detailed in Article 11 of the ITU Radio Regulations.


As the organisation responsible for managing Australia’s non-treaty inputs to the ITU, the ACMA will notify the ITU Radiocommunication Bureau (the ‘Bureau’) of proposed assignments.


The issue, including conditions associated with the issue, of an apparatus licence authorising the operation of a HF land mobile service may be dependent on the Bureau’s findings in relation to the proposed assignment.
