you can set your vhf and uhf, lower and upper frequency limit with CHIRP, so I would imagine since they are selling the radio with 40 pre-programmed channels in it ,, they are just using CHIRP to set the frequency limits outside of the 2m and 70cm ham bands and programming all the radios with the same channel list,,,, still doesn't make them legal to use on murs or gmrs or whatever frequency's they are programming in them
