GMRS radios operate at a wider bandwidth than FRS.  Radio programming may require software to set the proper bandwidth on a radio not dedicated to FRS or GMRS only.  Range and sound quality will be slightly less when the band width is set wrong on one radio and correct on the other being conversed with.  (Some older FRS radios may have different channel layouts, based on the brand.)
