GMDSS Radio Operator's License (DO)

Description

The DO qualifies the holder to operate, and make some basic equipment adjustments to, Global Maritime Distress and Safety System (GMDSS) radio installations. It also confers the operating authority of the MP.

Qualifications

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.

Term of License

A DO is issued for the holder's lifetime. (Prior to March 25, 2008, the license term for a DO was five years. Any holder of a DO that expired prior to March 25, 2008, must still file an application to renew the license within the five-year grace period after expiration.)

How to Obtain a License

Submit FCC Form 605 along with the appropriate Proof of Passing Certificates (for the requisite written examination elements). Use the FCC Form 605 and the FCC Form 159 (fee processing form) to renew a license or to replace a lost, stolen, or mutilated license. Many Commercial Operator License Examination (COLE) Managers file these documents for applicants who test with them. Ask your COLEM if it provides this service to its customers.

Examinations

To obtain an FCC Commercial Operator License, applicants must submit, to the Commission, proof of passing written and/or telegraphy Elements as illustrated in the following:

Element 1 - Basic radio law and operating practice with which every maritime radio operator should be familiar. To pass, an examinee must correctly answer at least 18 out of 24 questions.

Element 7: GMDSS Radio Operating Practices. GMDSS radio operating procedures and practices sufficient to show detailed practical knowledge of the operation of all GMDSS sub-systems and equipment. The exam consists of questions from the following categories: general information, narrow-band direct-printing, INMARSAT, NAVTEX, digital selective calling, and survival craft. To pass, an examinee must correctly answer at least at least 75 out of 100 questions.

or

Element 7R: Restricted GMDSS Radio Operating Practices. Fifty questions concerning those GMDSS radio operating procedures and practices that are applicable to ship stations on vessels that sail exclusively in sea area A1, as defined in sections 80.1069 and 80.1081 of the Commission's Rules. To pass, an examinee must correctly answer at least 38 out of 50 questions.
