If the regulations say that the amateur radio service is a secondary user of a frequency band, and another service is a primary user, what does this mean?
- AAmateur radio operators are allowed to use the frequency band only if they do not cause interference to primary users
- BNothing special: all users of a frequency band have equal rights to operate
- CAmateur radio operators are only allowed to use the frequency band during emergencies
- DAmateur radio operators can only use the band briefly for radio testing and adjustment purposes
Correct answer: A — Amateur radio operators are allowed to use the frequency band only if they do not cause interference to primary users. From the official ISED question bank, verified word for word.
Why
When a band is shared, being a secondary user means you must step aside if a primary user needs the frequency. The full explanation — and one for every question — is in Pro.
