IMPORTANT INFORMATION CONCERNING

UHF CB RADIO

TheuseoftheCizenBandradioserviceislicensedinAustraliaby

 TheclasslicenceforusersandequipmentoperangintheCB/PRS

477 MHz band has been amended. This radio meets the new 80

channel standard.

 Insimpletermsthesameamountofspectrumisavailable;

however,radiotransceiverscannowoperateinanarrower

bandwidth and hence use less spectrum. These radios are

generallyreferredtoasnarrowbandor12.5kHzradios.

Byusing12.5kHzchannelspacinginsteadof25kHz,the40

channelsoriginallyallocatedcannowbeexpandedto80channels

therebydoublingthechannelcapacityandrelievingcongesonin

the UHF CB/PRS band.

 Original40channelwidebandRadioswillconnuetooperateon

theoriginal40channels,howevertheywillnotbeabletoconverse

on the newer channels 41 – 80. The newer narrowband radios will

beabletoconversewithallolder40channelwidebandradioson

all channels 1 to 40 as well as the newer channels allocated from

41 to 80.

The mixing of narrowband and wideband radios in the same

spectrumcancausesomepossibleoperangissuesofinterference

andvaryinglevelsofreceivedvolume.
