Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain radio receivers and how they work, describe their types and history, support choosing and using receivers, and support electronics learning and radio hobby questions.

An electronic device that receives radio waves and converts the information they carry into usable form such as sound, data or images, from crystal sets and valve receivers to transistor radios, clock radios, communications receivers, radio direction finders and software-defined receivers in phones and computers, comprising antenna, tuning, amplification, demodulation and output stages; radio receivers underpin broadcasting, communications, navigation and radio astronomy.

What it is for: Devices receiving radio signals.

It can be explain operation; describe types and history; support choosing and using; support learning.

Distinguishing features

Antenna and tuning

Demodulation

Many bands and modes

Embedded in devices

What it looks like

Boxes with tuning controls and speakers, or circuits inside devices.

How it is recognised

Receives and demodulates radio waves

Broadcast, communications, direction finding, software-defined

A transmitter sends signals; a transceiver does both
