The General Mobile Radio Service (GMRS) is a North American land-mobile FM UHF radio service designed for short-distance two-way communication. It is commonly used on live steam railroads for dispatcher to engineer, or engineer to engineer communications.
Unlike FRS, GMRS requires a license in United States but can be used license-free in Canada. GMRS radios include the channels of FRS and can be used together.
FRS and GMRS radios are readily available at departments stores or online through Amazon, eBay and others.
Here is a procedure for obtaining a GMRS license from the Federal Communications Commission (FCC). This procedure was written in May 2010. It might not match the latest edition of the FCC registration website.
Any individual in the United States who is at least 18 years of age may apply for a GMRS license by completing the application form and paying the license fee ($85.00 as of May 2010). No exam is required. A GMRS license is issued for a 5-year term. GMRS radio equipment may be used by the licensed individual as well as his or her immediate family members.
