Hello, Ken... thank you for the inquiry. GMRS frequencies are not much different from FRS - except for the output power considerations, license requirements and wideband emission being common. You already know about the ID requirements, but let us furnish you with a link to GMRS regulations so you can bookmark it for any references that you may need in the future.
