What should you do before you transmit on any frequency?

A.
Make sure the SWR on your transmission line is high enough
B.
Check your antenna for resonance at the selected frequency
C.
Increase power to ensure someone will hear you
Correct Answer
D.
Listen to make sure others are not using the frequency

B-002-004-001

First, listen for a little while then ask, "Is this frequency in use?" ( QRL? in Morse ).

If you contact another station and your signal is extremely strong and perfectly readable, what adjustment should you make to your transmitter?

A.
None, continue with your contact
Correct Answer
B.
Turn down your power output to the minimum necessary
C.
Bypass your antenna tuner
D.
Turn on your speech processor

B-002-004-002

Amateurs should always use the minimum power required.

You need to transmit to adjust your antenna tuner prior to joining an HF single-sideband net that is in progress. On what frequency should you make the adjustment?

Correct Answer
A.
3 kHz to 5 kHz away from the net frequency
B.
On the net frequency
C.
On the band's centre frequency
D.
1 kHz away from the net frequency

B-002-004-003

You need to be careful not to interfere with the net or other stations already on the air, find a free frequency not too far from the net frequency.

How can on-the-air interference be minimized during lengthy transmitter testing?

A.
Use a non-resonant antenna
B.
Use a resonant antenna
Correct Answer
C.
Use a dummy load
D.
Choose an unoccupied frequency

B-002-004-004

The 'dummy load' (a resistor with a high power rating) dissipates RF energy as heat without radiating the RF on the air. Permits tests or adjustments without causing interference to other stations.

Why would you use a dummy load?

Correct Answer
A.
To test or adjust your transceiver without causing interference
B.
It is faster to tune
C.
To give comparative signal reports
D.
To reduce output power

If you are the net control station of a daily HF net, what should you do if the frequency on which you normally meet is in use just before the net begins?

A.
Reduce your output power and start the net as usual
B.
Cancel the net for that day
C.
Increase your power output so that net participants will be able to hear you over the existing activity
Correct Answer
D.
Ask occupants if they would change frequency, otherwise move to a clear frequency

B-002-004-006

A 'net' (short for network) is an activity carried on a given day and time at a known frequency where stations exchange information. Although no given station is entitled to any specific frequency (regardless of qualification, power or affiliation), stations would normally yield to an established daily net but if not, you need to move the net away.

If a net is about to begin on a frequency that you and another station are using, what should you do?

A.
Increase your power output to ensure that all net participants can hear you
B.
Transmit as long as possible on the frequency so that no other stations may use it
C.
Turn off your radio
Correct Answer
D.
As a courtesy, move to a different frequency

If propagation changes during your contact and you notice increasing interference from other stations on the same frequency, what should you do?

A.
Tell the interfering stations to change frequency, since you were there first
Correct Answer
B.
Move to another frequency
C.
Increase your output power
D.
Report the interference to your Section Manager at Radio Amateurs of Canada (RAC)

When selecting a single-sideband voice transmitting frequency, what minimum frequency separation from a contact in progress should you allow to minimize interference?

A.
150 Hz to 500 Hz
B.
Approximately 6 kHz
C.
Approximately 10 kHz
Correct Answer
D.
Approximately 3 kHz

B-002-004-009

In order of bandwidth requirements: CW = about 100 Hz, RTTY = about 600 Hz, AM = 6 kHz, SSB = 2 to 3 kHz, FM = 10 to 20 kHz. Minimum frequency separation: CW = 150 to 500 Hz, RTTY = 250 to 500 Hz, SSB = 3 kHz to 5 kHz.

What is a band plan?

Correct Answer
A.
A voluntary division of an amateur radio band to avoid interference between incompatible modes
B.
A schedule of operating restrictions within a band prescribed by Innovation, Science and Economic Development Canada
C.
A schedule of additional band allocations for recommendation to the International Telecommunication Union
D.
A plan devised by a club for the effective use of a frequency band during a contest

B-002-004-010

"Band plans" are published by Amateur organizations to suggest specific modes in specific segments of the band. The idea is to minimize interference and allow interest groups to find one another.

Before transmitting, the first thing you should do is:

A.
ask if the frequency is occupied
B.
make an announcement on the frequency indicating that you intend to make a call
C.
decrease your receiver's volume
Correct Answer
D.
listen carefully so as not to interrupt communications already in progress

B-002-004-011

First, listen for a little while then ask, "Is this frequency in use?" ( QRL? in Morse ).
