Editing General Mobile Radio Service (section)

==History==
The predecessor to GMRS was named '''Class&nbsp;A Citizens Radio Service''' when it was commissioned in the 1940s. Tube-type transceivers were used, and transmitter power was limited to 60 watts (plate input power to the final amplifier tube). The original service ran wideband FM with ±15&nbsp;kHz transmitter deviation and 50&nbsp;kHz channel spacing. At the time, this was the norm for all U.S. land mobile services. There was also a Class&nbsp;B Citizens Radio Service which used a different set of 461&nbsp;MHz channels and was limited to five&nbsp;watts output. Business users were permitted to license in this radio service. Radios were built by consumer electronics firms and commercial two-way radio vendors.

In the 1960s, the UHF 450–470&nbsp;MHz band was re-allocated to 25&nbsp;kHz channels. This meant transmitter deviation was reduced to ±5&nbsp;kHz. This doubled the number of channels available across the entire 450–470&nbsp;MHz band. Class&nbsp;B Citizens Radio Service channels were re-allocated to other radio services.

In the 1970s, allowed power was again changed to 50&nbsp;watts across the output terminals of the transmitter. In 1987, licensing of business users was discontinued and businesses were allowed to continue operating until their licenses expired. There was congestion on all channels in larger [[metropolitan statistical area]]s and moving businesses to [[Business band|Business Radio Service]] channels would provide some relief. The radio service was changed to its present name; General Mobile Radio Service or GMRS.

In 2010 the [[U.S. Federal Communications Commission]] (FCC) proposed removing the individual licensing requirement. In 2015, the FCC ruled to keep the license requirement, but to remove the regulator fee for licensing.<ref>{{cite web |url=http://transition.fcc.gov/Daily_Releases/Daily_Business/2015/db0521/FCC-15-59A1.pdf |title=FCC-15-59A1 |series=Daily Releases }}</ref> Adopted on May 20, 2015, the ruling would be in effect after a 90&ndash;day notification period to Congress; the fee will not be eliminated before August 18, 2015.<ref>{{cite web |url=http://transition.fcc.gov/Daily_Releases/Daily_Business/2015/db0521/FCC-15-59A1.pdf |title=FCC-15-59A1 |page=9}}</ref> The fee for a 5&ndash;year license was $90, with the regulatory fee portion of the license at $5&nbsp;per year (or $25 for the 5&ndash;year life of the license). After the notification period, the fee for a 5&ndash;year license was to become $65. The change became effective on September 3, 2015. 

Effective September 28, 2017, FCC revised the definition of the FRS service. FRS operation is now permitted with up to 2&nbsp;watts on the shared FRS/GMRS channels. The FCC will not grant certification for hybrid radios that would exceed the limits for the FRS  service on the FRS channels. Current "hybrid" FRS/GMRS radios will not require a GMRS license for power up to 2&nbsp;watts, but FRS radios will still not be permitted to use the input frequencies of GMRS repeaters. Any radio exceeding the limits of the new FRS service will be classified as a GMRS radio.<ref name=FCC-GMRS-FRS-Reform-2017>{{cite web |url=http://transition.fcc.gov/Daily_Releases/Daily_Business/2017/db0522/FCC-17-57A1.pdf |title=FCC Part 95 Personal Radio Services Rules Reform |publisher=Federal Communications Commission |access-date=May 19, 2017 |quote=Paragraphs&nbsp;51 and 52 list the changes on the FRS / GMRS channels and power restrictions. These modifications are meant to affect previous FRS / GMRS hybrid radios in the United States that were commonly sold to redefine them as FRS radios, since many users that purchase these radios did not know the FCC license requirements. As a result, these users will not require a GMRS license. Radios transmitting higher than the new FRS power restrictions are re-defined as GMRS radios and users will require a GMRS license to use these devices. The changes (channels and power limitations) went into effect on September 28, 2017. |df=mdy-all}}</ref>

On September 30, 2019, it became unlawful in the United States to import, manufacture, sell, or offer to sell radio equipment capable of operating under both GMRS and FRS.<ref name=PRS_reform_2018Aug29>{{cite web |url=https://www.federalregister.gov/documents/2017/08/29/2017-17395/personal-radio-service-reform |title=47 CFR § 95.1792 |series=Personal Radio Service reform |date=August 29, 2017}}</ref>
