Remember that 4 meters is not legal in the US; where it is a small band available in Europe. The 4 meter band frequencies fall into the same range as some of our original 13 VHF TV channels for over the air broadcasting. Channels 2-4 are 54 MHz to 72MHz and Channels 5-6 are 76MHz to 88 MHz according to frequency allocation chart. I'm pretty sure that any US models would not have that option.?
