While true, it's important to remember that not all ham radios that can transmit on GMRS bands are legal to do so. GMRS and FRS don't have the same "anything goes" allowances that ham operators have. Radios for these bands must be purpose built for these bands. Of course no one is going to know your compliant GMRS/FRS transmissions are coming from part 97 radio. Although most quality ham radios don't allow transmission on anything but the ham bands. The increased FCC enforcement of these Chinese radios means that many now have extra filters to reduce spurious emissions outside the ham bands, meaning they shouldn't work as well on GMRS and FRS.
