Description
Compact 477MHz UHF CB Radio with Advanced Signal Management and DSP 40-Channel Upgradable to 80, Australian Made, 3-Year Warranty
Product Overview
The GME TX3500 is a rugged, compact 477MHz UHF CB radio engineered and manufactured in Australia one of the first Australian radios designed to the ACMA 80-channel UHF CB standard introduced in 2011. Simple to install via a slide-in mounting cradle, the die cast chassis is built for demanding and harsh operating environments.
The TX3500 ships as a 40-channel radio upgradable to 80 channels. Digital Signal Processing technology delivers superior performance over conventional analogue radios; the Advanced Signal Management System (ASM) suppresses interference for clearer audio. Dynamic Volume Control automatically adjusts for ambient noise; the graphic signal strength meter provides a clear visual indication of received signal quality.
Physical rotary controls for squelch, channel, and volume give intuitive operation. CTCSS and DCS privacy codes, Selcall with quiet mode, open and group scan, duplex channels, voice inversion scrambling, full spectrum LCD backlighting, rear mic option, and 19 dealer-programmable receive channels (403–520MHz) complete the feature set.
The TX3500's DIN-sized companion is the TX4500. Both are part of GME's TX3500/TX4500 series.

Frequently Asked Questions
What is Advanced Signal Management (ASM) and how does it help?
GME's Advanced Signal Management System is an interference suppression feature that processes incoming signals to reduce the impact of co-channel interference — other users transmitting on the same frequency. In busy UHF CB environments (mine sites, construction, high-traffic highways), multiple users on the same channel can create overlapping audio. ASM helps isolate the stronger or intended signal for clearer reception.
What are the 19 dealer-programmable receive channels?
The TX3500 includes 19 receive-only channels that a dealer can program to specific frequencies within the 403–520MHz range. This extends receive-monitoring capability beyond the UHF CB band to other services in the broad VHF/UHF spectrum. Unlike the TX3440's 59 user-programmable channels (programmed by the operator), these 19 channels require dealer programming. Confirm available dealer programming services with your supplier.
What is the difference between the TX3500 and the TX4500?
The TX3500 and TX4500 are companion products in the same series. The TX4500 is DIN-sized, allowing it to fit into a standard single-DIN in-dash slot for a clean factory-integrated installation. The TX3500 is the non-DIN compact version. Both offer equivalent features; the choice is primarily determined by installation preference and available dash space.
What is the slide-in mounting cradle and how does installation work?
The slide-in cradle is a bracket that mounts permanently in the vehicle; the TX3500 radio body slides into the cradle and locks in place. This allows the radio to be removed quickly without tools — useful for vehicles where radio theft is a concern or where the vehicle is shared. The cradle remains in place; the radio can be taken out and secured separately.
How does the 3-year warranty through GME's service network work?
The TX3500 carries a 3-year parts and labour warranty serviced through GME's nationwide service network in Australia. This means warranty repairs are handled by authorised GME service centres across the country — not just the purchasing dealer — providing Australia-wide warranty coverage. Confirm current service centre locations with GME.
