Yes, the low power setting is only applicable to the channel you are on, if you want to change all channels to LO, you would need to change to LO in the settings for every channel.

CTCSS, or Continuous Tone Coded Squelching System, is an option that allows your UHF radio(s) to only pick up radio signals preceded by a “code”. This option helps to cut down on unwanted radio chatter. This is also known as PL, Private Line, Channel Guard, etc.

A Repeater is a Radio Relay Station. It is used when the radio signal needs to be magnified to get the desired distance coverage. It works by receiving a radio signal from one unit, magnifying it and retransmitting the signal to another radio unit. It would be used in an area where coverage was hindered by terrain, buildings or other environmental conditions.

There is a list of repeater stations across Australia. This list and the operational status of the repeaters can change so please check with the ACMA for the latest information on repeaters.

A handheld can absolutely supplement your in-vehicle communication, and many people use them successfully in this way. However, a fixed-mount in-vehicle radio with a quality external antenna will generally outperform a handheld in terms of range and clarity, particularly in remote areas. For serious bush travel or convoy use, a fixed-mount radio combined with a handheld offers the most versatile setup.

Yes. Because all UHF CB radios in Australia operate on the same 80-channel UHF CB frequency band, Oricom handhelds are fully compatible with other brands of UHF CB radio. Simply ensure all users are on the same channel and you can communicate regardless of brand or model.

Range depends heavily on your environment. A direct line-of-sight with no obstructions gives the best result, while buildings, hills, and dense bush all reduce range. Elevation is your biggest ally — the higher you position the radio, the further it will reach. In open terrain with clear line-of-sight, a 5W radio can achieve impressive distances. In more challenging environments, expect range to be reduced accordingly.

UHF CB (Citizen Band) radios operate on the 477 MHz UHF band, which is a free, open frequency band allocated specifically for public use in Australia. No licence is required to buy or operate a UHF CB radio — anyone can use one straight out of the box.
