Resources — Best Amateur Radio Sites

ARRL

The national association for amateur radio in the US. Licensing manuals, the annual Repeater Directory, band plans, advocacy, and the QST magazine archive.

Start here. The ARRL effectively writes the books most hams study from, and its band-plan charts are the reference everyone uses.

RepeaterBook

The largest worldwide repeater directory. Search by location, frequency, or callsign; export to your radio's programming software.

The single most useful tool for a new operator. Find every repeater near you, complete with offset and PL tone, before you program your radio.

QRZ

Callsign lookup, operator profiles, forums, and practice exams. The default place to look up who you just talked to.

The community's address book. The practice-exam tool is a genuinely good free way to drill before test day.

HamStudy

Free license exam preparation with adaptive flash cards covering the Technician, General, and Extra question pools.

The fastest path from zero to a Technician ticket. Most people pass after a week of the daily flash-card sessions.

AMSAT

The amateur satellite organization — build, launch, and operate through ham radio satellites in orbit.

Where the hobby gets ambitious. Working a contact through an orbiting satellite with a handheld is one of ham radio's best moments.
