Revision as of 21:56, 6 July 2015

The Cobra PR-245 supports 22 FRS/GMRS channels and 38 privacy codes. The manufacturer claims that the PR-245 has a maximum range of up to 6 miles. As with any FRS walkie talkie, the 6 mile range claim would be under ideal conditions with no obstructions line of sight. The radio supports channel scan and allows you to choose from 5 different call tones. Each PR-245 two way radio requires 4 AAA batteries.

These radios are typically sold in pairs. A pair retailed new at around $35.00. This model has been discontinued.

These radios transmit at two different power settings depending on the channel selected.

• For FRS only channels this unit transmits at 500mW.
• Fpr GMRS channels this unit transmits at 1 full watt.

These radios modulate at 2.5khz narrow band.

This 2-way radio operates on GMRS (General Mobile Radio Service) frequencies at over 500mW which requires an FCC (Federal Communications Commission) license. A user must be licensed or covered under a family license prior to operating on Channels 1 through 7 or 15 through 22, which comprise the GMRS channels of this radio.

Some models are setup for rechargeable via dock charger.
