You are required to comply with the rules of a class licence if you intend to operate common radio equipment on shared frequencies.
There are 17 class licences covering a range of equipment and devices. Each class licence sets out:
- what equipment you can use
- the frequency range to use
- the rules for using it.
Please note, you don't need to apply for a licence but are required to comply with the operational and technical requirements as set out in the relevant equipment rules.
