The amateur 4 metre band is located just above 70 MHz.
Equipment
The 4 metre band is available to amateurs in certain countries in Region 1, but is not available in the United States, Japan or Australia. This makes manufactured radio equipment for the band very rare. Most amateurs use homebrew or modified gear to operate on 4 metres.
Different countries have different 4 metre band edges, as shown in this band chart.
