What transmitter power should Canadian amateur radio operators use at all times?
- A 560 watts PEP output
- B The minimum legal power necessary to communicate
- C 400 watts PEP output
- D 560 watts DC input
Correct answer: B — The minimum legal power necessary to communicate. From the official ISED question bank, verified word for word.

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.
