Clubs are how amateur radio reproduces itself. They teach the classes, run the exams, hold the repeater license, put Field Day in a public park, mentor the operator who just passed a Technician exam and cannot bring themselves to transmit, and supply the volunteers that county emergency managers rely on. This section is about that side of the hobby — the organizational and community work rather than the radios.

NARA resources for clubs: the Find a Club directory is free to join, clubs can request a speaker from the National Presenters Panel or promotional material for a public event, and state and regional club councils connect clubs to each other.
