Overview of President JOHNNY III CB Radio (TXUS653) | New
The President JOHNNY III CB Radio (TXUS653) is a 40-channel mobile CB that is small, feature-rich and ideal for drivers who desire powerful performance in a small package. It usually combines AM CB coverage with contemporary features like automatic squelch, noise filtering and quick access to important emergency or highway channels. It is designed for off-road travel, highway use and work trucks. Its compact design is perfect for trucks, SUVs and overlanding vehicles where every square inch counts since it fits neatly into cramped dashboards or bespoke installations.

You can easily adjust volume, squelch, RF gain and other features with intuitive front-panel buttons without having to take your eyes from the road for extended periods of time. Long journeys are less taxing because to contemporary features like automatic squelch control (ASC), noise blanker and hi-cut audio, which assist reduce static and ignition noise. Whether you are outfitting a brand-new truck or renovating an existing rig, the small box and simple wiring make installation easier.
