Commercial Radio Operator License Program


Third Class Radiotelegraph Operator's Certificate (T3)


The T3 authorizes operation of certain coast radiotelegraph stations. It also confers the operating authority of the MP.


To qualify, you must:

Term of License

The T3 is issued for a period of five (5) years. These licenses may be renewed at any time within the last ninety (90) days of their term up until five years following expiration without having to re-take an examination. After the five-year grace period expires, applicants must retake the requisite written and/or telegraphy examination(s). An expired certificate is not valid for any radio operations.

As of May 20, 2013, the Commission no longer accepts applications for new T3 licenses, and T3 licenses for which renewal applications are filed are renewed as MP licenses. Former T3 holders who are renewed as MPs retain examination credit for Telegraphy Elements 1 and 2.

How to Obtain a License

Use the FCC Form 605 and the FCC Form 159 (fee processing form) to renew your license or to replace a lost, stolen, or mutilated license.
