The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" and to differentiate it from commercial broadcasting, public safety , or professional two-way radio services.
Amateur radios require a special amateur license to use but offer some advantages over GMRS radios for certain uses. Amateur radios are used for general communications among hobbyists, are great for emergency use, and the equipment is typically better quality than average GMRS radios.
