900 MHz Radios
900 Mhz two way radios have several advantages: they can be used without a license, they use frequency hopping technology that makes them practically eavesdrop proof, and they often have advanced cell-phone like functionality such as text messaging and direct calling of another radio through a contact list. They operate well indoors, similar to high powered UHF radios, but typically do not deliver as much range over land outdoors.
