How Amateur Radio Works
Unlike broadcast radio stations, amateur radio allows two-way communication. Operators transmit signals and receive responses from other stations.
Communication may occur using voice, Morse code, digital modes, or data transmissions.
Common Amateur Radio Bands
- HF (High Frequency) for long distance communication
- VHF (Very High Frequency) for local and regional communication
- UHF (Ultra High Frequency) for local communication and repeaters
Licensing
In most countries, including Canada, amateur radio operators must pass an examination and obtain a license before transmitting.
Licensing ensures operators understand radio regulations and basic technical concepts.
