Radio Explained is an independent guide to radio as a technology and a hobby: how broadcasting works, why reception behaves the way it does, and how receivers and antennas actually perform.
What this site is not
It is not a shop. It does not sell, source, quote for or repair equipment, and it does not act as a dealer for any manufacturer. It is not affiliated with, endorsed by, or connected to any company that previously used this domain name, or to any business with a similar name.
Why it exists
Radio is unusually well documented at the two extremes — simple consumer advice on one side, engineering texts on the other — and rather poorly served in between. The aim here is the middle: enough physics to understand why something happens, without equations.
Rules differ by country
Frequency allocations, licensing classes and what may lawfully be received or recorded vary between countries and sometimes within them. Articles say so rather than presenting one country’s rules as universal, and point you to your own national regulator. Transmitting requires a licence almost everywhere.
A safety note
Vintage mains-powered sets can store a lethal charge in their capacitors long after being unplugged, and old insulation degrades. Articles here describe what restoration involves rather than instructing you through it, because that work belongs to someone who already knows how to do it safely.
How it is written
Articles are drafted with AI assistance from a structured outline and checked against a quality gate — minimum depth, no invented specifications, prices or model numbers, and no writing in the voice of a dealer. Corrections: [email protected].
