What Is the GROL and Why It Matters for Radio Professionals

The GROL, or General Radiotelephone Operator License, is issued by the FCC and authorizes holders to adjust, maintain, and repair radio transmitting equipment at FCC-licensed stations. It combines two examination elements: Element 1 (Marine Radio Operator Permit) and Element 3 (General Radiotelephone), though many candidates pursue Element 3 directly if they already hold Element 1. The GROL is required for technicians who service land mobile radio systems, aviation radio equipment, and certain maritime electronics.

Who Needs a GROL License

Any technician who makes internal adjustments to FCC-licensed transmitters operating on frequencies where a licensed operator is required must hold a GROL. This includes avionics repair technicians, two-way radio shop technicians, and engineers maintaining broadcast transmitter equipment at commercial radio and television stations.

GROL License Cost

The cost to obtain a GROL license is relatively low compared to other professional certifications. Fees are paid to the testing center, not the FCC directly.

GROL Questions and Answers

How much does it cost to get a GROL license?

The FCC application fee for a GROL license is $50, paid through the FCC CORES system when you file FCC Form 605. Additionally, you will pay an exam session fee to the Commercial Operator License Examination Manager (COLEM) administering your test, typically ranging from $25 to $100 depending on the testing organization.

What is the difference between a GROL and a MROP license?

A GROL (General Radiotelephone Operator License) covers Elements 1 and 3, authoring operation and maintenance of most land and maritime radio systems. A MROP (Marine Radio Operator Permit) only requires Element 1 and limits you to operating ship radar and certain maritime stations. The GROL provides broader authority for adjusting and maintaining radio transmitters across multiple service types.

How many questions are on the GROL exam?

The GROL exam consists of two elements. Element 1 (Marine Radio Operator Permit) contains 24 multiple-choice questions with a passing score of 75%, requiring at least 18 correct answers. Element 3 (General Radiotelephone) contains 100 multiple-choice questions, also requiring a 75% passing score, meaning you must answer at least 75 questions correctly.

Can I take the GROL exam online?

No, the GROL exam must be taken in person at an FCC-authorized Commercial Operator License Examination Manager (COLEM) testing site. Organizations such as iNARTE, ETA International, and the National Radio Examiners offer testing sessions at locations across the United States. You must schedule your exam through one of these approved COLEMs and bring valid government-issued photo identification.

What topics should I study for the Element 3 exam?

Element 3 covers operating procedures, radio wave propagation, radio practice, electrical principles, circuit components, practical circuits, signals and emissions, and antennas and feedlines. You should also study FCC rules and regulations governing commercial radio services, as well as safety practices for working with high-voltage transmitting equipment. Questions are drawn from a publicly available FCC question pool.

Do I need a GROL to work on aviation radio equipment?

Yes, a GROL is required to adjust, maintain, or internally repair most aviation radio transmitters and certain radar systems. The FCC mandates that technicians servicing avionics radio equipment at repair stations hold a valid GROL. Many aviation employers list the GROL as a job requirement, and the FAA expects radio work at certified repair stations to be performed by FCC-licensed operators.

Can I add a radar endorsement to my GROL?

Yes, you can add a Ship Radar Endorsement by passing Element 8, which covers radar operating principles, safety techniques, and maintenance procedures for marine radar systems. You can also add a GMDSS Radio Maintainer endorsement by passing Element 9. These endorsements expand the scope of equipment you are authorized to install and maintain under your existing GROL license.

What happens if my GROL license expires?

GROL licenses are issued for a lifetime and do not expire under current FCC rules. Once granted, your General Radiotelephone Operator License remains valid indefinitely without renewal fees or continuing education requirements. However, if your license was issued before 1984, it may have had an expiration date, and you should verify your license status through the FCC Universal Licensing System (ULS).
