70-centimeter Band - Band Allocation

Band Allocation

The band allocation vary regionally. In the United States, Australia and Trinidad and Tobago the band ranges from 420 to 450 MHz with some geographical limitations; in Canada, the band is only 430–450 MHz; in the UK, amateurs are allocated 430–440 MHz. By international treaty between the US and Canada, operation in the portion of the band from 420 to 430 MHz is prohibited north of Line A, which runs just south of the Canadian border from Washington state to Maine, and east of Line C, which runs from northeast to southeast Alaska.
