Apparatus Callsigns

Call signs are a unique series of letters and/or numbers allocated to a radiocommunications user for identification purposes.

At the start of each transmission the licensee of an Earth, Earth receive, Space, and Space receive station must use either:

  1. a form of identification that clearly identifies that station

  2. a call sign allocated by the Australian Communications and Media Authority (the ACMA)

Call signs allocated to stations have to conform to International Telecommunication Union Radio Regulations and must be used for all on-air communications including testing.
