1What is the minimum passing score for the FCC Element 3 (General Radiotelephone) examination?
A.60 out of 100 questions
B.70 out of 100 questions
C.75 out of 100 questions
D.80 out of 100 questions
Explanation: To pass the FCC Element 3 examination, an examinee must correctly answer at least 75 out of 100 questions (75%). This exam covers electronic fundamentals and techniques required to adjust, repair, and maintain radio transmitters and receivers used in aviation, maritime, and international fixed public radio services.
2What examination elements are required to obtain a General Radiotelephone Operator License (GROL)?
A.Element 1 and Element 6
B.Element 1 and Element 3
C.Element 3 and Element 8
D.Element 1, Element 3, and Element 9
Explanation: The FCC General Radiotelephone Operator License (GROL) requires passing Element 1 (Basic Radio Law and Operating Practice) and Element 3 (General Radiotelephone). Element 6 is for Radiotelegraph, Element 8 is the Ship Radar Endorsement, and Element 9 is for GMDSS Radio Maintainer. Adding Element 8 to a GROL gives the Ship Radar Endorsement.
3A GROL holder is required to adjust, maintain, or internally repair FCC-licensed radiotelephone transmitters in which services?
A.Amateur and Citizens Band radio services
B.Aviation, maritime, and international fixed public radio services
C.Broadcast television and cable services only
D.Personal communications and Wi-Fi services
Explanation: The General Radiotelephone Operator License is required to adjust, maintain, or internally repair FCC-licensed radiotelephone transmitters in the aviation, maritime, and international fixed public radio services. It also conveys all of the operating authority of the Marine Radio Operator Permit (MP). Amateur radio requires a separate amateur license, and broadcast services have different licensing requirements.
4What is the term of a General Radiotelephone Operator License issued by the FCC?
A.5 years
B.10 years
C.20 years
D.Lifetime
Explanation: A General Radiotelephone Operator License (GROL) is issued for the holder's lifetime. Commercial radio operator licenses issued on or after May 20, 2013 are valid for the lifetime of the holder and do not need to be renewed. Licenses issued before that date may have different terms and should be checked for renewal requirements.
5Who administers the FCC commercial operator license examinations?
A.The FCC directly at regional offices
B.Commercial Operator License Examination Managers (COLEMs)
C.State licensing boards
D.The Federal Aviation Administration (FAA)
Explanation: The FCC does not administer commercial operator license examinations directly. Instead, examinations are administered by Commercial Operator License Examination Managers (COLEMs) authorized by the FCC. COLEMs such as ETA International, Exemplar Global (iNARTE), ISCET, and others offer exams at locations nationwide and, in some cases, online with remote proctoring.
6What is the FCC application fee for a new commercial radio operator license?
A.$15
B.$25
C.$35
D.$50
Explanation: As of April 19, 2022, the FCC has implemented a $35 application fee to process new commercial radio operator license applications. This fee is paid directly to the FCC after passing the required exam elements. The COLEM exam fees are separate and vary by provider, typically ranging from $50 to $90 for the GROL exam elements.
7What is the FCC Registration Number (FRN) used for?
A.It is the frequency assigned to your radio station
B.It identifies your radio equipment model
C.It is a unique identifier required for all FCC licensing transactions
D.It is your amateur radio call sign
Explanation: An FCC Registration Number (FRN) is a unique identifier assigned to individuals and entities who interact with the FCC. It is required for all FCC licensing transactions, including applying for a commercial operator license. Before taking FCC exams, candidates must create an FCC user profile and obtain an FRN through the FCC's CORES (Commission Registration System) website.
8According to Ohm's Law, what is the current flowing through a 50-ohm resistor with 100 volts applied across it?
A.0.5 ampere
B.2 amperes
C.5 amperes
D.5000 amperes
Explanation: Ohm's Law states that I = V/R, where I is current in amperes, V is voltage in volts, and R is resistance in ohms. Therefore, I = 100V / 50 ohms = 2 amperes. This fundamental relationship is essential for calculating current, voltage, and resistance in all electronic circuits.
9What is the total resistance of three 30-ohm resistors connected in parallel?
A.10 ohms
B.30 ohms
C.90 ohms
D.270 ohms
Explanation: For identical resistors in parallel, the total resistance equals one resistor's value divided by the number of resistors: R_total = R/n = 30/3 = 10 ohms. Alternatively, using the parallel formula: 1/R_total = 1/30 + 1/30 + 1/30 = 3/30 = 1/10, so R_total = 10 ohms. Parallel resistance is always less than the smallest individual resistor.
10What is the unit of measurement for electrical capacitance?
A.Henry
B.Ohm
C.Farad
D.Watt
Explanation: The farad (F) is the SI unit of electrical capacitance, named after Michael Faraday. One farad is the capacitance of a capacitor that stores one coulomb of charge with one volt across it. The henry is the unit of inductance, the ohm is the unit of resistance, and the watt is the unit of power. Common subunits include microfarads (uF), nanofarads (nF), and picofarads (pF).

Frequently Asked Questions

What is the FCC General Radiotelephone Operator License (GROL)?

The GROL is an FCC commercial radio license required to adjust, maintain, or internally repair FCC-licensed radiotelephone transmitters in aviation, maritime, and international fixed public radio services. It requires passing Element 1 (Basic Radio Law, 24 questions) and Element 3 (General Radiotelephone, 100 questions) and is issued for the holder's lifetime.

How many questions are on the GROL exam?

The GROL consists of two exam elements: Element 1 has 24 multiple-choice questions and requires 18 correct; Element 3 has 100 multiple-choice questions and requires 75 correct. FCC does not set a universal session time—each COLEM controls its examination format and timing. The current Element 3 pool is organized into 100 subtopics under 17 lettered topics, 3-A through 3-Q.

Where can I take the GROL exam?

GROL exams are administered by Commercial Operator License Examination Managers (COLEMs) authorized by the FCC. The FCC does not administer exams directly. Major COLEMs include ETA International, Exemplar Global (iNARTE), ISCET, Mariners Learning System, and National Radio Examiners. Many COLEMs offer both in-person testing at locations nationwide and online proctored exams you can take from home.

How much does the GROL exam cost?

The total cost for obtaining a GROL is approximately $85-$175. COLEM exam fees range from $50-$90 for a session covering up to 2 elements (varies by provider). Additionally, the FCC charges a $35 application fee paid directly to the FCC after passing. The FCC question pools are available for free download from the FCC website, so study materials can be obtained at no cost.

How long is the GROL valid?

The GROL is issued for the holder's lifetime and has no FCC continuing-education requirement. If you pass only one required written element, retain the COLEM-issued examination credit and complete the other element before applying.

What careers require a GROL?

GROL-related work includes maintaining or internally repairing FCC-licensed radiotelephone transmitters in aviation, maritime, and international fixed public radio services. Whether a particular job requires or merely prefers the credential depends on the station, equipment, duties, and employer.

Do I need any prerequisites to take the GROL exam?

There is no formal education prerequisite or employer sponsorship requirement. Applicants must meet FCC commercial-operator eligibility, including spoken-English ability and U.S. employment eligibility. FCC does not publish a fixed GROL retake waiting period, so confirm retesting terms with the administering COLEM.
