The FCC General Radiotelephone Operator License, designated PG and commonly called the GROL, authorizes its holder to adjust, maintain, and internally repair FCC-licensed radiotelephone transmitters used in the aviation, maritime, and international fixed public radio services. To earn one, you pass two written exams (Elements 1 and 3) through an FCC-authorized exam manager, then file Form 605 electronically with a $35 regulatory fee. The license is good for life.
What the License Authorizes
A GROL holder can service FCC-licensed radiotelephone transmitters in aviation, maritime, and international fixed public radio services. It also grants full operating authority for compulsorily equipped ship radiotelephone stations above 1,500 watts peak envelope power and voluntarily equipped ship or aeronautical stations above 1,000 watts peak envelope power.1Federal Communications Commission. Commercial Radio Operator Types of Licenses
The GROL automatically carries the operating authority of the Marine Radio Operator Permit (MP), the credential required for operators aboard vessels carrying more than six passengers for hire when station power stays at or below 1,500 watts peak envelope power.2eCFR. 47 CFR Part 80 Subpart D – Operator Requirements If you hold a PG, you do not need a separate MP.
Radar work is a separate matter. Only a commercial license carrying a Ship Radar Endorsement authorizes the holder to repair, maintain, or internally adjust ship radar equipment. GROL holders can add the endorsement by passing Element 8, a 50-question exam that requires at least 38 correct answers.1Federal Communications Commission. Commercial Radio Operator Types of Licenses
What the GROL Does Not Cover
The GROL does not authorize at-sea repair or maintenance of Global Maritime Distress and Safety System (GMDSS) equipment. That work requires the separate GMDSS Radio Maintainer’s License (DM), which adds Element 9 covering GMDSS maintenance for Sea Areas A3 and A4.1Federal Communications Commission. Commercial Radio Operator Types of Licenses If your career involves servicing GMDSS installations aboard SOLAS-convention vessels, the DM is what you need.
Who Can Apply
Eligibility turns on technical competence rather than experience. You must be legally eligible for employment in the United States. There is no minimum age and no U.S. citizenship requirement.3eCFR. 47 CFR 13.9 – Eligibility and Application for New License or Endorsement Foreign nationals holding U.S. pilot certificates can apply for the purpose of operating aircraft radio stations, and foreign pilots from countries with a reciprocal agreement with the United States are also eligible if their foreign certificate is valid here.
You are ineligible if your commercial radio operator license is currently suspended or subject to a pending suspension proceeding. You also have to be able to transmit and receive spoken messages in English; complete deafness, complete muteness, or any condition preventing telephone communication in English is disqualifying.3eCFR. 47 CFR 13.9 – Eligibility and Application for New License or Endorsement
The Two Required Exams
The FCC does not administer these tests. Commercial Operator License Examination Managers (COLEMs) do, and you can pass the elements in separate sittings.1Federal Communications Commission. Commercial Radio Operator Types of Licenses
Element 1: Basic Radio Law and Operating Practice
Element 1 covers ship station rules, distress protocols, and standard operating procedures. It has 24 multiple-choice questions, and you need at least 18 correct to pass.4Federal Communications Commission. Examinations
Element 3: General Radiotelephone
Element 3 is the heavier exam. It tests the electronics fundamentals used to adjust, repair, and maintain radio transmitters and receivers: electrical principles, circuit components, radio wave propagation, signals and emissions, and antenna systems. It has 100 multiple-choice questions, and you need at least 75 correct.4Federal Communications Commission. Examinations
Credit and Retakes
If you already hold an unexpired FCC commercial radio operator license, you get credit for the elements that license required. A Marine Radio Operator Permit, for example, satisfies Element 1, so you would only need to pass Element 3 to earn the GROL.5eCFR. 47 CFR Part 13 – Commercial Radio Operators There is no mandatory waiting period after a failed element, but the COLEM cannot re-administer the same set of questions to the same examinee. You can sit again as soon as another session is available, drawing a fresh set from the question pool.
Finding a Testing Location and Paying Exam Fees
The FCC maintains a directory of approved COLEMs with contact information and testing locations.6Federal Communications Commission. Commercial Operator License Examination Managers Some run fixed test centers, some travel to test sites, and some proctor online. Each COLEM sets its own exam fee, typically about $25 to $100 per session depending on how many elements you take and whether the fee includes electronic filing. This is separate from the FCC’s $35 regulatory fee for the license itself.
Filing the Application
When you pass an element, the COLEM issues a Proof of Passing Certificate (PPC). You have 365 days from the pass date to file your license application. During that window, the PPC actually authorizes you to exercise the privileges of the license you applied for, so work can begin while the FCC processes the application.7eCFR. 47 CFR 13.13 – Application for a Renewed or Modified License Miss the 365-day deadline and you lose credit for those elements, meaning you’ll retest.
Before filing, you need an FCC Registration Number (FRN), created through the Commission Registration System (CORES).8FCC. FCC CORES – Register for a New FRN The ten-digit FRN is used for all FCC transactions.
The application is FCC Form 605, filed through the Universal Licensing System (ULS). Select “NE – New” as the purpose and attach the Proof of Passing Certificates for Elements 1 and 3.9Federal Communications Commission. Applying for a New License in the Universal Licensing System Some COLEMs file on your behalf and retain the original PPC on file for one year. The regulatory fee is $35, paid online through CORES during filing.10Federal Communications Commission. Personal Service and Amateur Application Fees Once approved, the grant posts to ULS and is downloadable as a PDF.
Character Disclosures on Form 605
Form 605 asks whether you or any party to the application has ever been convicted of a felony in any state or federal court. A “yes” requires a written explanation of the circumstances and why granting the license still serves the public interest.11Federal Communications Commission. FCC 605 Main Form – Information and Instructions A felony conviction is not an automatic disqualification, but concealing one can be. The FCC weighs willfulness, recency, and frequency of offenses.
You also certify that you are not subject to a denial of federal benefits under the Anti-Drug Abuse Act of 1988 for a controlled substance conviction. A willfully false statement on the application is itself a federal offense under 18 U.S.C. § 1001, punishable by fine and imprisonment, and can result in revocation of any FCC license issued to you.11Federal Communications Commission. FCC 605 Main Form – Information and Instructions
License Term, Duplicates, and Older Licenses
Commercial radio operator licenses are valid for the lifetime of the holder, with no periodic renewal and no renewal fee.12eCFR. 47 CFR 13.15 – License Term If you hold a GROL issued before the lifetime-term rule took effect and it still carries an expiration date, you can file a renewal through ULS on Form 605 with the applicable fee.13Federal Communications Commission. Commercial Radio Operator License Program Lost or destroyed licenses can be replaced through ULS as well; the official authorization is always available for download from the ULS License Manager.
Penalties for Operating Without the License
Working on equipment that requires a GROL without holding one violates the Communications Act. A willful and knowing violation can bring a criminal fine of up to $10,000 and up to one year in prison; a second offense doubles the maximum imprisonment to two years.14GovInfo. 47 USC Chapter 5 Subchapter V – Penal Provisions
The FCC can also impose civil forfeiture penalties without a criminal proceeding. For violations without a more specific penalty category, the current inflation-adjusted maximum is $25,132 per violation or per day of a continuing violation.15Federal Communications Commission. Inflation-Adjusted Maximum Forfeiture Penalties Employers who allow unlicensed personnel to perform work that requires a licensed operator face liability as well.
