TR-121CP          TR-121WX

Ranger's traditional series of affordable CB radios bring you high performance, small size, and uncluttered simplicity. The TR-121CP with internal Public Address (PA) amplifier or TR-121WX with weather receiver are ideal for the leisure vehicle market and vehicle-to-vehicle communications. Typical applications for the TR-121 series are RV caravans, dune buggies, ATVs, and Jeep Posses.

In the dunes, canyons and gullies, these radios can communicate where others, such as the FRS or business radios, cannot. FRS radio frequencies require line of sight and operate with very low output power. CB frequencies can bend, penetrate and access others that VHF and UHF (FRS) are unable to reach.

— High Performance in a small package	— Uncluttered Simplicity
— Built-in VHF Weather Radio (TR-121WX)	— High Performance Receiver Design
— PA Feature (TR-121CP)	— Phase-locked loop Circuitry
— Maximum Talk Power without Flat-topping	— Full Size Microphone Included
— Illuminated Power/Signal Strength Meter	— External Speaker Jack

TR-121CP AM Mobile This model features a large, easy-to-read channel indicatior, front panel mike plug, seperate volume and squelch controls, and a two-function meter for monitoring incoming signal strength and output power. Exclusive to this model is "Talkback" for listening to the transmitted signal and Public Address (PA) circuitry. PA is especially useful in emergencies or for talking to bystanders outside a vehicle.

TR-121WX AM Mobile The TR-121WX features an internal VHF weather receiver in place of the TR-121CP's PA and "Talkback" capabilities. The weather receiver can tune into any of the six most common NOAA weather channels.

For the ultimate in economy, the TR-100 Series is the perfect choice.
