Commercial Licenses : General Radiotelephone Operator License (PG)

A General Radiotelephone Operator License (PG), or better known as GROL, is required to adjust, maintain, or internally repair FCC licensed radiotelephone transmitters in the aviation, maritime, and international fixed public radio services. The GROL is, by far, the most popular - accounting for more than 80% of all commercial radio operator licenses issued by the FCC. The GROL conveys all of the operating authority of the Marine Radio Operator Permit (MP).

It is also required to operate the following:

  • any maritime land radio station or compulsorily equipped ship radiotelephone station operating with more than 1500 watts of peak envelope power.

  • voluntarily equipped ship and aeronautical (including aircraft) stations with more than 1000 watts of peak envelope power (or pleasure maritime HF radio stations).

To qualify, you must:

  • be a legal resident of (or otherwise eligible for employment in) the United States; and

  • be able to receive and transmit spoken messages in English; and

  • pass a written and/or telegraphy examination(s) as described below under Examinations.
The GROL Licenses are issued for the holder's lifetime.
