The RT22 is one of the first high power 2 watt FRS radios available. It is FCC type 95 approved (meaning legal to use without a license*.) We buy them in bulk so a pair can be had for a mere $25 already programmed (and that price will drop soon!) these are short range radios 1/2 mile to 2 miles is the practical range, great for connecting a neighborhood. Contact Mel@CAVERN.mobi for information or to get one.

BTECH GMRS-V1

The BTECH GMRS-V1 is a 5 Watt GMRS repeater capable radio/scanner. Transmitting requires a GMRS $70 10-year family license. It can be purchased directly from Amazon but Mel@CAVERN.mobi often has some pre-programmed on hand. Price varies $50-60. Practical range is 1-5 miles but with a repeater 20-100+ is normal. Also works as a scanner which can monitor Calfire, Sheriff, weather, Ham radio and more.
