Full description
Prepare for five FCC commercial radio operator licences in one app, with the real question pools and every answer explained. This is the study aid for the General Radiotelephone Operator License (GROL) and the GMDSS family: the GMDSS Radio Operator's License, the Restricted GMDSS Radio Operator's License, the Ship Radar Endorsement and the GMDSS Radio Maintainer's License. Choose your licence and the app draws the exact elements it needs. WHY THIS APP Every question is the real, word for word FCC pool question with the official answer, plus a plain-English explanation we write ourselves. - 2,224 real FCC pool questions from Elements 1, 3, 7, 7R, 8 and 9 - 2,224 flashcards for the rules, formulas and GMDSS procedures - A licence picker that builds the right mock for each licence - Timed mock exams that gate each element at its official pass mark - Weak-area review and a per-topic readiness score A REALISTIC MOCK EXAM Each element is passed on its own at about 75 percent. Element 1 needs 18 of 24; Elements 3 and 7 need 75 of 100; Elements 7R, 8 and 9 need 38 of 50. The in-app mocks mirror this and are an unofficial study target. THE EXAM TOPICS Radio law and operating practice, electronics and radio theory, GMDSS distress, urgency and safety, DSC and MMSI, Inmarsat, MF/HF and VHF-DSC, maritime safety information, survival craft and SAR, ship radar principles, and GMDSS equipment maintenance. STUDY YOUR WAY - Works fully offline, no account, no sign-up - Progress stays on your device - One-time purchase, no subscription ABOUT This is an independent study aid and is not affiliated with, endorsed by, or an official product of the Federal Communications Commission or any government body. Questions are reproduced from the FCC commercial operator license question pools, which are works of the U.S. federal government in the public domain (17 U.S.C. 105).
