  • The General Radiotelephone Operator License, or GROL, is a commercial license, as opposed to an amateur radio license. It allows the holder to operate, maintain or install certain classes of United States licensed radio and television transmitters under authority of the Federal Communications Commission. Specifically, the FCC GROL is required to operate or work on any maritime land radio station or compulsorily equipped ship radiotelephone station operating with more than 1500 watts of peak envelope power and any voluntarily equipped ship and aeronautical (including aircraft) stations with more than 1000 watts of peak envelope power. They are also required for international broadcast stations, such as the Voice of America. The license also conveys all of the operating authority of the Marine Radio Operator Permit. This is required to operate or work on radiotelephone stations aboard vessels weighing more than 300 gross tons, that carry more than six passengers for hire in the open sea or any coastal/tidewater area of the United States, aboard certain vessels that sail the Great Lakes, and to operate and repair certain aviation radiotelephone stations and certain coast radiotelephone stations. GROL does not confer licensing authority to operate or maintain GMDSS or radiotelegraph commercial stations. These, however, are more specialized transmitters. Because of its wider nature the GROL is the most popular FCC commercial license, accounting for about 80% of those issued by the Commission. Like all FCC commercial licenses (except the radiotelegraph ones, which have pictures of the holders) the GROL is issued for the lifetime of the licensee. A license that can be added to the GROL (as well as the GMDSS maintainer and the radiotelegraph licenses) is "Ship Radar Endorsement. " This allows the holder to install, service, and maintain Radar systems on board vessels. In the past, the FCC issued the GROL in yellow 8.5 x 11 inch "diploma-like" form. It is now issued in a wallet-sized form.
