List of Tricky Exam Questions

Questions from the exam bank that are a bit tricky and could use some explanation follow. (suggestions welcome)

Note: From time to time, the government changes the order of the answers for exam questions, to prevent people from memorizing the answer letter. The answer order, and thus their letters in these examples may be different that the current exam bank, but the concepts still apply.

Questions explained (18): 8-2-6, 1-6-2, 1-7-7, 1-9-1, 1-9-9, 1-10-9, 1-13-2, 6-4-2, 1-2-5, 1-3-6, 1-22-2, 1-6-4, 1-6-5, 1-8-2, 1-9-6, 6-11-2, 3-17-9, 5-9-5, 5-12-5
Questions about to be added: caught up.

B-008-002-006  (A) 

An amateur transmitter is being heard across the entire dial of a broadcast receiver. The receiver is most probably suffering from:

A) 
audio rectification in the receiver
B)  harmonics interference from the transmitter
C)  
poor image rejection
D)  
splatter from the transmitter
Explanation:


B-001-006-002 (A)

An amateur station may be used to communicate with:

A)  stations operated under similar authorizations
B)  any stations which are identified for special contests
C)  armed forces stations during special contests and training exercises
D)  any station transmitting in the amateur bands

Explanation:

This is a catch. "any station transmitting in the amateur bands" seems reasonable until you think that this other station may be operating unlawfully without a license. "Similarly licensed stations" is a much better answer. Amateurs are not allowed to knowingly conduct conversations with unlicensed stations.



B-001-007-007 (B)

What are the restrictions on the use of abbreviations or procedural signals in the amateur service?


A)  Only "10 codes" are permitted
B)  They may be used if the signals or codes are not secret

C)  
There are no restrictions
D)  They are not permitted because they obscure the meaning of a message to government monitoring stations

Explanation:

key word: SECRET. Specifically prohibited in the Radiocommunication Regulations.



B-001-009-001 (A)

Who is responsible for the proper operation of an amateur station?


A)  Both the control operator and the station owner
B)  Only the station owner who is the holder of an Amateur Radio Operator Certificate

C)  The person who owns the station equipment

D)  
Only the control operator
Explanation :

Both the licensee and the control operator ( a person other than the licensee who the owner may have left in charge of the station ) are responsible for proper operation of the station.



B-001-009-009 (A)

Which of the following statements is correct?


A)  Any person may operate an amateur station under supervision, and in the presence of, a person holding appropriate qualifications
B)  A person, holding only Basic Qualification, may operate another station on 14.2 MHz

C)  Radio amateurs may permit any person to operate the station without supervision

D)  Any person may operate a station in the amateur radio service

Explanation):

B): A Basic Qualification does not grant privileges below 30 MHz.  C) and D): The 'Control Operator' must be a licensed Amateur.



B-001-010-009 (A)

Which of the following is not correct? The operator of an amateur station:

A)  may make trials or tests, even though there is a possibility of interfering with other stations
B)  shall not cause harmful interference to a station in another service which has primary use of that band

C)  may conduct technical experiments using the station apparatus

D)  may make trials or tests, except if there is a possibility of interference to other stations

Explanation:

key words: NOT CORRECT.  B), C), and D) are true. Conducting tests which result in 'harmful interference' is prohibited.



B-001-013-002 (B)

How often must an amateur station be identified?

A)  At the beginning and end of each transmission
B)   At least every thirty minutes, and at the beginning and at the end of a contact

C)   At the beginning of a contact and at least every thirty minutes after that

D)  
At least once during each transmission
Explanation:

Station identification: your call sign in English or French, at the START and the END of a contact or test transmission and every 30 minutes at the most. Only Remote-Control transmissions to model craft need not include station identification.



B-006-004-002 (B)

What are some reasons to use parallel-conductor transmission line?

A)  It has a low impedance, and has less loss than coaxial cable
B)  It will operate with a high SWR, and has less loss than coaxial cable
C)  It has low impedance, and will operate with a high SWR
D)  It will operate with a high SWR, and it works well when tied down to metal objects
Explanation (See study guide section 7.3):

Short answer: If you're stuck with a high SWR, maybe due to antenna design, or condition, parallel conductor cable copes well with  it.

Long answer:

The high Characteristic Impedances and greater separation of the conductors in parallel lines DO permit high power and high Standing Wave Ratio (SWR) BUT nearby metallic objects can affect them and impedance matching is most often necessary at the transmitter end. Their high Characteristic Impedance permits carrying power with less current (P = R * I squared), less current implies less losses due to resistance.

B-001-002-005  (B)

The holder of an Amateur Radio Operator Certificate shall, at the request of a duly appointed radio inspector, produce the certificate, or a copy thereof, to the inspector, within ____ hours after the request:

A)  72

B-006-011-002 (C)

Approximately how long is the driven element of a Yagi antenna for 14.0 MHz?

A)  10.67 metres (35 feet)
B)  20.12 metres (66 feet)
C)  10.21 metres (33.5 feet)
D)  5.21 metres (17 feet)
Explanation:

Yagi driven elements are basically dipoles, which are half a wave length long.
For a frequency of 14.0 MHz, the wave length is 300 / 14.0 = 21.42 metres
So a half wave is 21.42 / 2 = 10.71
This is close to one of the answers, 10.67, but isn't the right one.

We need to apply the practical rule of thumb that applies to antenna lengths for frequencies below 30 MHz (or wave lengths over 10 metres)
This rule states that you should reduce antenna lengths by a factor of .95 for this range.

You can do this in 2 ways:
1) calculate the half wave length as we did above, and then take 95%, which works out to 10.71 * .95 = 10.17
2) assume that, for antenna purposes, (frequency * wave length) = 286 in this frequency range, rather than 300.
    In the above question:
         antenna wavelength = 286 /14.0 = 20.43
                       half of this =  20.43 / 2 = 10.21

For both of these methods, the closest answer is C) 10.21

The reason why the 2 methods don't precisely agree is because the 286 shortcut isn't exactly .95:  286/300 = .9533

The 95% factor is discussed in your study guide in section 8.5 Antenna Length


B-003-017-009 (D)

Your mobile HF transceiver draws 22 amperes on transmit. The manufacturer suggests limiting voltage drop to 0.5 volt and the vehicle battery is 3 metres (10 feet) away. Given the losses below at that current, which minimum wire gauge must you use?

A)  Number 14, 0.19 V per metre (0.06 V per foot)
B)  Number 12, 0.11 V per metre (0.03 V per foot)
C)  Number 8,   0.05 V per metre (0.01 V per foot)
D)  Number 10, 0.07 V per metre (0.02 V per
foot)
Explanation:

The voltage drop applies to the whole circuit, which starts at the battery's plus terminal, and ends at its negative terminal.

As someone pointed out in class, the distance between the radio and the battery is traversed twice in the circuit, probably using a cable that has 2 wires side by side:
- once from the battery's positive terminal to the radio
- once from the radio to the battery's negative terminal

Thus, we are dealing with 6 metres or 20 feet of wire length.

The maximum permitted voltage drop is 0.5 volt.

Metric calculation: .5 volt maximum drop, spread out over 6 metres, would be .5V / 6m = 0.083 Volts per metre.
Answer C, .05 V/m, and answer D, .07 V/m are both less than this calculated maximum of 0.083 V/m, but D is the minimum wire gauge of the two (#10 vs #8), as requested in the question.

Imperial calculation: .5 volt maximum drop, spread out over 20 feet, would be .5V / 20ft = 0.025 Volts per foot.
Answer C, .01 V/ft, and answer D, .02 V/ft are both less than this calculated maximum of 0.025 V/ft, but D is the minimum wire gauge of the two (#10 vs #8), as requested in the question.

The 22 Amp current given is unneeded extra information, apparently a decoy for the unwary

B-005-009-005 (C) 

What determines the inductance of a coil?

A)  The coil diameter, the number of turns of wire used to wind the coil and the type of metal used for the wire
B)  The core material, the coil diameter, the length of the coil and whether the coil is mounted horizontally or vertically
C)  The core material, the coil diameter, the length of the coil and the number of turns of wire used to wind the coil
D)  The core material, the number of turns used to wind the coil and the frequency of the current through the coil
Explanation:

Inductance in a coil is due to the interaction of the magnetic fields from one turn to the others. The ease of setting up a magnetic field through a suitable core material, the relative position of the turns (diameter and length) and the number of turns all contribute to inductance. The mounting direction, the type of metal, and the "frequency of the current" aren't relevant.

B-005-012-005 (A) 

When a parallel coil-capacitor combination is supplied with AC of different frequencies, there will be one frequency where the impedance will be highest. This is the:

A)  resonant frequency
B)  impedance frequency
C)  inductive frequency
D)  reactive frequency
Explanation:

It's tempting to rule out resonant frequency, because we generally want minimal impedance at resonance so the selected signal can get through. However, remember that we have two kinds of tuned circuits. Serial, where the coil and inductor are in series, and parallel where they're in parallel. In the serial case, the impedance is minimized at resonance, and the selected frequency is allowed to pass. In the parallel case, the impedance is maximized at resonance, and the selected frequency is prevented from passing through, i.e. it's filtered. The question specifies that we're talking about the parallel case, so maximum impedance is indeed achieved at the resonant frequency for that configuration. Study guide reference: section 4.16, Tuned Circuits, page 4-21.
