What Is Amateur Radio? A Beginner's Overview

Amateur radio, commonly called ham radio, is a licensed two-way communication service that lets individuals transmit and receive voice, data, Morse code, and digital modes across a wide range of frequencies. Unlike broadcast radio, amateur radio is interactive — licensed operators communicate directly with each other, without relying on cellular towers or the internet.

Who Uses Amateur Radio?

The FCC database lists more than 750,000 active amateur radio licensees in the United States alone. Operators include hobbyists who enjoy building their own equipment, emergency communicators who provide backup communications when disasters knock out normal infrastructure, satellite enthusiasts who bounce signals off amateur satellites in orbit, and DX chasers who try to contact stations in as many countries as possible.

Getting Licensed

To transmit on amateur radio frequencies in the US, you need an FCC-issued license. The FCC offers three classes — Technician, General, and Amateur Extra — each granting access to additional frequency bands and privileges. All three require passing a written multiple-choice exam. There is no Morse code requirement for any license class.

Finding Other Operators

Once licensed, your call sign becomes part of the public FCC database. You can search CallSignLookup by name, city, or call sign to find other operators, or browse by state to find hams in your area. The amateur radio community is welcoming — most operators are happy to help newcomers get on the air.
