Receive ultra-clear long distance reception with this pair of Cobra CXT227 two-way radios. Depending on terrain and conditions, the extended range capability provides up to 20 miles. There are 2662 channel combinations when the 22 channels are combined with the 121 privacy codes. The user's voice is detected and the radio transmits without the need to press any buttons, freeing hands for other tasks. Five VOX sensitivity levels allow the user to select at which point the radio will detect their voice. A unique circuit extends the life of the batteries. If there are no transmissions within 10 seconds, the unit will automatically switch to battery saver mode. The scan feature allows the user to scan either channels or privacy codes within a channel to locate conversations in progress. The Roger Beep Tone indicates the completion of the user's transmission and signals to others it is clear to talk. This feature is selectable and can be turned on or off. The Auto Squelch automatically shuts off weak transmissions or unwanted noise due to terrain or range conditions. Be prepared for storms and emergencies with the built-in NOAA radio receiver providing coverage of all government operated weather channels.
