B-001-10: Interference, determination, protection from interference
B-001-10-01:
What is a transmission called that disturbs other communications?
Harmful interference
Interrupted CW
Transponder signals
Unidentified transmissions
B-001-10-02:
When may you deliberately interfere with another station's communications?
Never
Only if the station is operating illegally
Only if the station begins transmitting on a frequency you are using
You may expect, and cause, deliberate interference because it can't be helped during crowded band conditions
B-001-10-03:
If the regulations say that the amateur service is a secondary user of a frequency band, and another service is a primary user, what does this mean?
Amateurs are allowed to use the frequency band only if they do not cause interference to primary users
Nothing special: all users of a frequency band have equal rights to operate
Amateurs are only allowed to use the frequency band during emergencies
Amateurs must increase transmitter power to overcome any interference caused by primary users
B-001-10-04:
What rule applies if two amateur stations want to use the same frequency?
Both station operators have an equal right to operate on the frequency
The station operator with a lesser class of licence must yield the frequency to a higher-class licensee
The station operator with a lower power output must yield the frequency to the station with a higher power output
Station operators in ITU Regions 1 and 3 must yield the frequency to stations in ITU Region 2
B-001-10-05:
What name is given to a form of interference that seriously degrades, obstructs or repeatedly interrupts a radiocommunication service?
Harmful interference
Intentional interference
Adjacent interference
Disruptive interference
B-001-10-06:
Where interference to the reception of radiocommunications is caused by the operation of an amateur station:
the Minister may require that the necessary steps for the prevention of the interference be taken by the radio amateur
the amateur station operator is not obligated to take any action
the amateur station operator may continue to operate without restrictions
the amateur station operator may continue to operate and the necessary steps can be taken when the amateur operator can afford it
B-001-10-07:
Radio amateur operation must not cause interference to other radio services operating in which of the following bands?
430.0 to 450.0 MHz
7.0 to 7.1 MHz
144.0 to 148.0 MHz
14.0 to 14.2 MHz
B-001-10-08:
Radio amateur operations are not protected from interference caused by another service operating in which of the following frequency bands?
902 to 928 MHz
144 to 148 MHz
220 to 225 MHz
50 to 54 MHz
B-001-10-09:
Which of the following is NOT correct? The operator of an amateur station:
may make trials or tests, even though there is a possibility of interfering with other stations
shall not cause harmful interference to a station in another service which has primary use of that band
may conduct technical experiments using the station apparatus
may make trials or tests, except under circumstances that preclude the possibility of interference with other stations
