When may you deliberately interfere with another amateur radio station's communications?

  • Correct Answer
    Deliberate interference is never acceptable
  • Only if the station is operating illegally
  • Only if the station begins transmitting on a frequency you are using
  • Only when you are operating within crowded band conditions

Deliberate harmful interference is ALWAYS prohibited.

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?

  • Amateur radio operators can only use the band briefly for radio testing and adjustment purposes
  • Amateur radio operators are only allowed to use the frequency band during emergencies
  • Nothing special: all users of a frequency band have equal rights to operate
  • Correct Answer
    Amateur radio operators are allowed to use the frequency band only if they do not cause interference to primary users

Primary User and Secondary User are statuses assigned to different services when frequency bands are allocated by Innovation, Science and Economic Development Canada. "Stations of a secondary service: a) shall not cause harmful interference to stations of primary service, b) cannot claim protection from harmful interference from stations of a primary service". For example, on 430-450 MHz and 902-928 MHz, the Amateur Radio Service has secondary status behind other services.

What rule applies if two amateur radio operators want to use the same frequency?

  • The station operator with a lesser qualification must yield the frequency to an operator of higher qualification
  • Correct Answer
    Both station operators have an equal right to operate on the frequency
  • Station operators in regions 1 and 3 of the International Telecommunication Union must yield the frequency to stations in region 2
  • The station operator with a lower power output must yield the frequency to the station with a higher power output

Common sense and respect are expected out of amateurs in sharing radio spectrum. No organization, qualification or activity can claim exclusive and priority use of a given frequency.

In the event the Minister of Innovation, Science and Industry determines that an amateur radio station causes harmful interference, what are the Minister's powers?

  • Revoke the amateur radio operator's certificate without giving written notice
  • Correct Answer
    Order the station's operation to cease or change
  • Delegate the matter to the Canadian Radio-television and Telecommunications Commission
  • Convene the parties to arrive at a compromise solution

"The Department shall order the persons in control of the equipment to cease or modify operation until such time it can be operated without causing interference". (Radiocommunication Regulations)

Amateur radio operation must not cause interference to other radio services operating in which of the following bands?

  • 7.0 MHz to 7.1 MHz
  • 14.0 MHz to 14.2 MHz
  • Correct Answer
    430.0 MHz to 450.0 MHz
  • 144.0 MHz to 148.0 MHz

Primary User and Secondary User are statuses assigned to different services when frequency bands are allocated by Innovation, Science and Economic Development Canada. "Stations of a secondary service: a) shall not cause harmful interference to stations of primary service, b) cannot claim protection from harmful interference from stations of a primary service". For example, on 430-450 MHz and 902-928 MHz, the Amateur Radio Service has secondary status behind other services.

  • 222 MHz to 225 MHz
  • 144 MHz to 148 MHz
  • 50 MHz to 54 MHz

  • After warning other stations who might be interfered with
  • Only between the hours of midnight and 8:00 AM

Conducting tests which may result in 'harmful interference' is prohibited.
