80 Channel Upgrade Instructions

Upgrading your Compatible GME UHF CB Radio to 80 Channels*

The ACMA (Australian Communications and Media Authority) have recently released a new class licence allowing UHF CB radios to operate on a new 80 channel narrow band standard.
In December 2010, in preparation for this new standard, GME began building UHF CB radios that complied with both the original 40 channel wideband standard and the new 80 channel narrowband standard. This allowed customers to purchase 'future proofed' 40 channel radios prior to the release of the new standard that could be switched to the new 80 channel standard once it was mandated. As of June, 2011, owners of compatible radios can now operate on the new 80 channel narrow band channels.

GME radios that are 80-channel compatible can be easily identified by an '80 Channel Upgradable' sticker on the packaging and by the following serial number prefixes.

All models with serial number prefix's 011 (November 2010) or earlier as well as TX4400 and TX4600 models with serial number prefix's 101 (January 2011) or earlier are unfortunately not able to be upgraded to 80 channel narrow band operation. From serial number 106xxxxxx onwards, all the above models will be factory enabled for 80 channel operation.

Compatible GME radios can be either User upgraded or Dealer upgraded depending on the model. Please refer to the table above.
