Specifies the radiofrequency requirements for land mobile and fixed services equipment to meet Australian radiofrequency spectrum arrangements, and the methods of test for their verification. Operational and marking details required in relation to the spectrum arrangements are also specified.

This Standard applies to analogue speech (angle modulated) equipment operating in the VHF and UHF land mobile and fixed services radiofrequency bands in the range 29.7 MHz to 1 GHz. Limits for frequencies above 520 MHz are under consideration.Categories of equipment within this range include -(a) base, mobile, personal mobile and RF control stations operating in the designated land mobile bands in the frequency range 29.7 MHz to 1 GHz with channel spacings of 12.5 kHz, 20 kHz or 25 kHz in Australia;(b) fixed point to point and point to multipoint equipment operating in the designated single channel fixed service bands in the frequency range 29.7 MHz to 1 GHz with channel spacings of 12.5 kHz or 25 kHz; and(c) personal mobile, fixed and repeater equipment operating in Australia in the maritime mobile service and used for on-board communications in the frequency band 450 MHz to 470 MHz.
