70 centimeters

70 Centimeters is a common ham radio band in the UHF spectrum. Although the exact usable frequency range varies regionally, the 70 centimeter band generally ranges from 430 to 450 MHz. Increasingly, 'local' radios are being produced for "dual band" use, meaning they are capable of operation on both 70 centimeters and 2 Meters. Curiously, most of these radios skip over the 220 MHz ham band.
