Description
477MHz UHF CB Mobile Transceiver Full LCD Microphone, 59 Extra Programmable Receive Channels, 5-Digit Selcall, DIN-Mount Option, Australian Made
Product Overview
The GME TX3440 is a practical and versatile 477MHz UHF CB mobile transceiver. Its full-function LCD microphone provides all controls and display at the operator's hand, while the compact main unit (128mm × 117mm × 29mm) can be mounted in tight locations. An optional MBD001 DIN adapter kit allows in-dash installation into a standard DIN slot for a clean, integrated appearance.
A standout feature is the 59 extra user-programmable receive-only channels covering 403–520MHz extending monitoring capability well beyond the UHF CB band. Combined with frequency band scanning, this makes the TX3440 capable of receive-monitoring a broad range of RF activity across the 403–520MHz spectrum.
Other key features include digital signal strength meter, user selectable duplex for repeater operation, 5-digit Selcall with quiet mode, user adjustable squelch, and 50 CTCSS codes for privacy filtering. Australian Made. Three-year warranty.

Frequently Asked Questions
What are the 59 extra programmable receive channels (403–520MHz)?
The TX3440 includes 59 receive-only channels that the user can program to any frequency within the 403–520MHz range. This extends the radio's receive capability far beyond the standard UHF CB band (476–477MHz) — allowing monitoring of other VHF/UHF services such as commercial radio, emergency services, and other licensed users in the 403–520MHz spectrum, within Australian regulatory limits for receive-only monitoring. These are receive channels only — the TX3440 transmits only on the authorised UHF CB frequencies.
What is frequency band scanning?
Frequency band scanning allows the TX3440 to scan across a programmed set of frequency bands (including the extra 403–520MHz receive channels) looking for active signals. This is distinct from UHF CB channel scanning, which only covers the 40 or 80 UHF CB channels. Frequency band scanning makes the TX3440's expanded receive capability practically usable.
What is the MBD001 DIN adapter and when would I use it?
The MBD001 is an optional mounting kit that adapts the TX3440 to install into a standard single-DIN in-dash slot — the same slot used by car stereo head units. This allows the TX3440 to be installed in the dash for a clean, factory-integrated appearance, rather than surface or under-dash mounting. It is purchased separately from the TX3440.
How does the TX3440 compare to the TX3340?
Both are ultra compact UHF CB radios with full-function LCD microphones, Selcall, duplex channels, and open/group scan. The TX3440 adds the digital signal strength meter, 59 extra programmable receive channels (403–520MHz), and frequency band scanning. The TX3340 includes the 80-channel upgrade path. Confirm current specifications for both models with GME as these may have been updated.
What is the warranty period on the TX3440?
The TX3440 carries a 3-year manufacturer's warranty, which is confirmed in the product data.
