What transmitter power should Canadian amateur radio operators use at all times?
- A560 watts PEP output
- BThe minimum legal power necessary to communicate
- C400 watts PEP output
- D560 watts DC input
Correct answer: B — The minimum legal power necessary to communicate. From the official ISED question bank, verified word for word.
Why
Canadian rules require you to use the lowest power that still gets your message across clearly, because high power can cause unnecessary interference to other stations and wastes energy. The full explanation — and one for every question — is in Pro.
