This Standard applies to analogue speech (angle modulated) equipment operating in the VHF and UHF land mobile and fixed service radiofrequency bands in the range 29.7 MHz to 1 GHz that are not subject to spectrum licensing arrangements.

This Standard applies to analogue speech (angle modulated) equipment operating in the VHF and UHF land mobile and fixed service radiofrequency bands in the range 29.7 MHz to 1 GHz that are not subject to spectrum licensing arrangements. 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 (in Australia see Clause 3.1.10) or 25 kHz;(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;(c) personal mobile, fixed and repeater equipment operating in the maritime mobile service and used for on-board communications in the frequency band 450 MHz to 470 MHz; and(d) Narrowband Area Service (NAS) transmitters used in Australia, with performance requirements identical to LMRS Base stations.Equipment operating in the land mobile services bands from 820 MHz to 825 MHz and 865 MHz to 870 MHz is not covered by the Standard. NOTE: For operation of land mobile equipment in these bands refer to the relevant frequency management authorities in Australia and New Zealand.
