Harmful Interference

1. B-001-10-1.... What is a transmission called that disturbs other communications?
harmful interference 
interrupted CW 
transponder signals 
unidentified transmissions 
No Answer
2. B-001-10-2.... 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 
No Answer
3. B-001-10-3.... 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 
No Answer
4. B-001-10-4.... 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 
No Answer
5. B-001-10-5.... What name is given to a form of interference that seriously degrades, obstructs or repeatedly interrupts a radiocommunication service?
intentional interference 
adjacent interference 
disruptive interference 
harmful interference 
No Answer
6. B-001-10-6.... Where interference to the reception of radiocommunications is caused by the operation of an amateur station:
the amateur station operator is not obligated to take any action 
it may continue to operate without restrictions 
the Minister may require that the necessary steps for the prevention of the interference be taken by the radio amateur 
the amateur station operator may continue to operate and the necessary steps can be taken when the amateur operator can afford it 
No Answer
7. B-001-10-7.... Radio amateur operation must not cause interference to other radio services operating in which of the following bands?
7.0 to 7.1 MHz 
144.0 to 148.0 MHz 
430.0 to 450.0 MHz 
14.0 to 14.2 MHz 
No Answer
8. B-001-10-8.... Radio amateur operations are not protected from interference caused by another service operating in which of the following frequency bands?
144 to 148 MHz 
220 to 225 MHz 
50 to 54 MHz 
902 to 928 MHz 
No Answer
9. B-001-10-9.... Which of the following is NOT correct? The operator of an amateur station:
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, even though there is a possibility of interfering with other stations 
may make trials or tests, except under circumstances that preclude the possibility of interference with other stations
