Cobra microTALK CXT345

The Cobra CXT345 microTALK is a two-way radio designed for convenient and easy communication, making it suitable for various activities such as hiking, biking, working, keeping track of family and friends at crowded events, checking with travel companions, talking with neighbors, and arranging meeting spots while shopping.

Function Description

The primary function of the Cobra CXT345 is two-way radio communication. It operates on 22 channels, with seven shared with FRS/GMRS, seven FRS-only, and eight GMRS-only. Additionally, it features 10 NOAA All Hazards Radio channels and a Weather Alert function, allowing users to listen to NOAA All Hazards Radio channels and receive emergency alerts from designated NOAA broadcast stations.

The radio incorporates 121 Privacy Codes (38 CTCSS codes and 83 DCS codes) to help reduce interference from other users on any given channel. It supports hands-free operation (VOX), automatically transmitting when the user speaks, with adjustable VOX sensitivity to match voice volume and avoid background noise triggers.

Other functions include:

Scan: Allows the radio to automatically scan channels and privacy codes, stopping when an incoming transmission is detected.
Call Alert: Transmits one of five selectable call tones to alert another person.
Roger Beep Confirmation Tone: An audible tone sounds when the Talk button is released, signaling to the other party that the transmission is complete.
Auto Squelch/Maximum Range: Automatically shuts off weak transmissions and unwanted noise. It also features a maximum range extender to receive all signals and extend the radio's range.
Button Lock: Locks the Channel Up, Channel Down, and Mode/Power buttons to prevent accidental operation.
