Welcome to Amateur Extra #

Welcome to the HamStudy Amateur Extra Class License HamBook! Perhaps you heard a rare station calling just below the General band edge, out of reach, and started thinking about an upgrade. You may also want to understand what happens inside your radio, improve a station, help others get licensed, or earn the highest license class. Whatever brought you here, let’s give those exam answers something to connect to.

Amateur Extra Class License

Amateur Extra Class License #

Amateur Extra is the highest of the three US amateur license classes. It adds access to portions of several HF bands that General operators cannot use. Those extra frequencies can be a quiet refuge when a contest packs the General segments, or your only way to reach a DX station working the Extra-only end of a band.

Your radio won’t gain any watts when the license arrives: the usual maximum power limit stays the same as for General. You gain more frequency choices, along with knowledge that can help you make better use of the station you have.

Understanding the Extra Exam #

The Amateur Extra exam, called Element 4, contains 50 multiple-choice questions. You must answer 37 correctly to pass. You won’t face a Morse code test; that requirement went away in 2007.

The questions come from a public pool maintained by the National Conference of Volunteer Examiner Coordinators. The pool this book covers contains 599 questions and is valid from July 1, 2024, through June 30, 2028. Check hambook.org for the latest book if you’re studying near a pool change.

How to Use This HamBook #

This HamBook helps you prepare for the Amateur Extra exam quickly or build a deeper understanding of radio theory and operation. The same sections support both approaches: highlights identify the exam facts, and the surrounding explanations help you understand and apply them.

The Two Parts #

Part 1: Advancing Radio Science extends familiar component and circuit behavior into the models and calculations used for modulation, digital processing, antennas, and propagation. Later sections use the models introduced earlier, so this is the place to return when an explanation depends on a concept you don’t yet understand.

Preparing for the Upgrade

Preparing for the Upgrade #

To earn an Amateur Extra Class License, you need credit for all three exams: Technician (Element 2), General (Element 3), and Amateur Extra (Element 4). A current General Class License supplies the lower-element credit, so most readers will take only Element 4. If you still need a lower exam, prepare for it first; an exam team may offer multiple elements in one session.

Find Your Exam Team #

Volunteer Examiners administer amateur exams through a Volunteer Examiner Coordinator. You can find in-person and remote sessions at HamStudy.org/sessions, or ask a local club about upcoming sessions.
