What is the correct way to call "CQ" when using voice?

  • Say "CQ" once, followed by "this is," followed by your call sign spoken three times
  • Say "CQ" at least five times, followed by "this is," followed by your call sign spoken once
  • Say "CQ" at least ten times, followed by "this is," followed by your call sign spoken once
  • Correct Answer
    Say "CQ" three times, followed by "this is," followed by your call sign spoken three times

A call to any station: "CQ" three times, "THIS IS", your call sign three times. Any word only spoken once might easily not get noticed.

How should you answer a voice CQ call?

  • Say your call sign twice, followed by "calling," then the other station's call sign
  • Say the other station's call sign at least five times, followed by "this is," then your call sign twice
  • Say the other station's call sign at least three times, followed by "this is," and your call sign at least five times
  • Correct Answer
    Say the other station's call sign once, followed by "this is," then your call sign

Anything spoken five or ten times is just overkill.

What is simplex operation?

  • Transmitting one-way communications
  • Transmitting on one frequency and receiving on another
  • Correct Answer
    Transmitting and receiving on the same frequency
  • Transmitting and receiving over a wide area

'Simplex' ( also known as direct ) operation where two stations use one frequency in turns contrasts with repeater operation (duplex) where two frequencies are used simultaneously ( the repeater output frequency and the repeater input frequency ). Stations should avoid tying-up a repeater for long periods of time when within range of one another on a simplex frequency. Most receivers can be switched to the repeater input frequency at the press of a button (this is useful to verify if simplex operation is possible with a given station).

When should you consider using simplex operation instead of a repeater?

  • When an emergency telephone call is needed
  • When you are travelling and need some local information
  • Correct Answer
    When signals are reliable between communicating parties without using a repeater
  • When the most reliable communications are needed

Why should local communications use VHF and UHF frequencies instead of HF frequencies?

  • Because signals are stronger on VHF and UHF frequencies
  • Because greater output power is permitted on VHF and UHF
  • Because HF transmissions are not propagated locally
  • Correct Answer
    To minimize clutter on HF bands more appropriate for long-distance communication

Always choose a frequency with the least reach so the spectrum remains usable elsewhere.

Why should you be careful in choosing a simplex frequency when operating VHF or UHF?

  • Some frequencies are designated for narrow band FM and others for wideband FM
  • Correct Answer
    To avoid inadvertently choosing a frequency that is the input to a local repeater
  • Implanted medical devices share the same spectrum
  • Some frequencies cannot accommodate simplex operation

Because repeaters use two frequencies, an input and an output, you could unknowingly choose a frequency which appears free, but happens to be the input of a repeater. Your transmissions would be rebroadcast and repeater users would be blocked from using the repeater. Amateur organizations publish 'band plans' which suggest what type of operation is advisable in which segments of the bands.

If you are talking to a station using a repeater, how would you find out if you could communicate using simplex instead?

  • By asking the other station to move 10 kHz away to test the path
  • By asking a third station to confirm it receives you both
  • Correct Answer
    By checking if you can clearly receive the station on the repeater's input frequency
  • By checking if you can clearly receive a more distant repeater

'Simplex' ( also known as direct ) operation where two stations use one frequency in turns contrasts with repeater operation (duplex) where two frequencies are used simultaneously ( the repeater output frequency and the repeater input frequency ).

If you are operating simplex on a repeater frequency, why would it be good practice to change to another frequency?

  • Because changing the repeater's frequency requires the authorization of Innovation, Science and Economic Development Canada
  • Correct Answer
    Because you may interfere with users of the repeater
  • Because the repeater's output power may overload your receiver
  • Because there are more repeater operators than simplex operators

If you operate simplex on a repeater frequency, you are preventing others from using the repeater. Amateur organizations publish 'Band Plans' where segments reserved for simplex operation are recommended.

Which sideband is commonly used for 20-metre voice operation?

  • Independent
  • Lower
  • Double
  • Correct Answer
    Upper

Choice of sideband: BELOW 10 MHZ ( 160 m, 80 m, 40 m ), use Lower Sideband (LSB). Above 10 MHz ( 20 m and up ), use Upper Sideband (USB). The new (2014) 60 metres band is an exception.

When calling a specific station on voice, what is the preferred format for your transmission?

  • Correct Answer
    The call sign of the desired station, followed by "this is" and your call sign
  • "CQ, CQ, CQ" followed by the call sign of the desired station
  • Your call sign repeated twice, the word "for" and the call sign of the desired station
  • Your call sign, followed by "calling" and the call sign of the desired station

'Beacons' are one-way automated stations maintained by amateurs which operate on known frequencies to permit evaluating propagation conditions.
