A T1 is required only for those who serve as the chief radio operator on a U.S. passenger ship equipped with a radiotelegraph station. It also conveys all of the operating authority of a T2.
To qualify, you must:
Term of License
The T1 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 T1 licenses, and T1 licenses for which renewal applications are filed are renewed as T licenses.
