Emission Designator Converter

Use this page to convert ACMA Emission Designator codes into a human readable explanation.

What is an Emission Designator

An emission designator sequence consists of nine alphanumeric characters, the first seven of which are compulsory. This sequence allows the government (through the Australian Communications and Media Authority) and all other interested parties to determine what type of transmission is occurring at any given site. All sites transmitting on a regulated band in Australia must register the details of their transmission to ACMA.

The sequence is broken down into three parts:
- The first four symbols provide the bandwidth of the transmission
- The following three symbols provide the modulation techniques used and the type of information transmitted (eg. television, telephony, data transmission)
- The last (optional) two symbols provide more information about the signal such as symbol rate, coding conditions, multiplexing techniques, etc.
