What transmitter power should Canadian amateur radio operators use at all times?

  • 560 watts DC input
  • 400 watts PEP output
  • Correct Answer
    The minimum legal power necessary to communicate
  • 560 watts PEP output

Amateurs shall use the minimum legal power necessary to communicate within these restrictions: BASIC Qualification = 250 watts DC input or 560 watts PEP ("where expressed as radio frequency output power measured across an impedance-matched load"). ADVANCED Qualification: 1000 watts DC input or 2250 watts PEP. The Morse Qualification has no bearing on the allowed power.

For single sideband (SSB) operation, what is the maximum transmitter peak envelope power (PEP) that an amateur radio station may use if the operator holds an Amateur Radio Operator Certificate with Advanced Qualification?

  • 190 watts
  • 250 watts
  • Correct Answer
    2250 watts
  • 560 watts

Key word: ADVANCED. Amateurs shall use the minimum legal power necessary to communicate within these restrictions: BASIC Qualification = 250 watts DC input or 560 watts PEP ("where expressed as radio frequency output power measured across an impedance-matched load"). ADVANCED Qualification: 1000 watts DC input or 2250 watts PEP. The Morse Qualification has no bearing on the allowed power.

You have determined the maximum transmitter power that meets RF exposure and radiated power limits. Where do you verify this power is NOT exceeded?

  • Correct Answer
    At the output of the transmitter or external amplifier
  • At the antenna feed point
  • At the antenna tuner output
  • At the power supply terminals

Measuring the "direct current input power" presumes that the current consumed strictly by the power amplifier and its working voltage are known. The "radio frequency output power" can be measured at the RF output connector of the power amplifier with a wattmeter. Of the two, this last one is more readily accessible.

For SSB operation on 3750 kHz, what is the maximum transmitter peak envelope power (PEP) that an amateur radio station may use if the operator holds an Amateur Radio Operator Certificate with Basic and Morse code qualifications?

  • 1000 watts
  • Correct Answer
    560 watts
  • 2250 watts
  • 1500 watts

Key word: BASIC. Amateurs shall use the minimum legal power necessary to communicate within these restrictions: BASIC Qualification = 250 watts DC input or 560 watts PEP ("where expressed as radio frequency output power measured across an impedance-matched load"). ADVANCED Qualification: 1000 watts DC input or 2250 watts PEP. The Morse Qualification has no bearing on the allowed power.

For SSB operation on 7055 kHz, what is the maximum transmitter peak envelope power (PEP) that an amateur radio station may use if the operator holds an Amateur Radio Operator Certificate with Basic Qualification with Honours?

  • Correct Answer
    560 watts
  • 2250 watts
  • 1000 watts
  • 200 watts

Key word: BASIC. Amateurs shall use the minimum legal power necessary to communicate within these restrictions: BASIC Qualification = 250 watts DC input or 560 watts PEP ("where expressed as radio frequency output power measured across an impedance-matched load"). ADVANCED Qualification: 1000 watts DC input or 2250 watts PEP. Achieving the Honours level has no bearing on the allowed power.

What is the maximum effective radiated power (ERP), expressed as peak envelope power (PEP), the holder of an Amateur Radio Operator Certificate with Advanced Qualification may use on 60 metres?

  • 560 watts
  • Correct Answer
    100 watts
  • 250 watts
  • 2250 watts

Key word: 60 METRES. "Amateur service operators may transmit in the frequency band 5 351.5-5 366.5 kHz and on the following four centre frequencies: 5 332 kHz, 5 348 kHz, 5 373 kHz and 5 405 kHz. Amateur stations are allowed to operate with a maximum effective radiated power of 100 W PEP in each channel..." (RBR-4)

  • Correct Answer
    1000 watts
  • 560 watts
  • 250 watts
  • 1500 watts

Key word: ADVANCED. Amateurs shall use the minimum legal power necessary to communicate within these restrictions: BASIC Qualification = 250 watts DC input or 560 watts PEP ("where expressed as radio frequency output power measured across an impedance-matched load"). ADVANCED Qualification: 1000 watts DC input or 2250 watts PEP. The Morse Qualification has no bearing on the allowed power.

On 630 metres and 2200 metres, what key antenna characteristic must be taken into account to comply with power limitations expressed as equivalent isotropically radiated power (EIRP)?

  • Correct Answer
    Gain
  • Resonance
  • Bandwidth
  • Impedance

Key word: 630 METRES. "The maximum equivalent isotropically radiated power (e.i.r.p.) of stations in the amateur service using frequencies in the band 472-479 kHz shall not exceed 1 W." (RBR-4) The equivalent isotropically radiated power is the power delivered to the antenna times the maximum gain of the antenna referenced to an isotropic radiator.

  • 750 watts
  • Correct Answer
    250 watts
  • 1000 watts

Key word: BASIC. Amateurs shall use the minimum legal power necessary to communicate within these restrictions: BASIC Qualification = 250 watts DC input or 560 watts PEP ("where expressed as radio frequency output power measured across an impedance-matched load"). ADVANCED Qualification: 1000 watts DC input or 2250 watts PEP. The Morse Qualification has no bearing on the allowed power.

Unless an operator holds an Amateur Radio Operator Certificate with Advanced Qualification, what is the maximum carrier power that an amateur radio station may use on emissions other than SSB?

  • 750 watts
  • 250 watts
  • 560 watts
  • Correct Answer
    190 watts

"The holder of an Amateur Radio Operator Certificate with Basic Qualification is limited to a maximum transmitting power of: (a) where expressed as direct-current input power, 250 W to the anode or collector circuit of the transmitter stage that supplies radio frequency energy to the antenna; or (b) where expressed as radio frequency output power measured across an impedance-matched load, (i) 560 W peak envelope power for transmitters that produce any type of single-sideband emission, or (ii) 190 W carrier power for transmitters that produce any other type of emission". (RBR-4, Restrictions on Capacity and Power Output)". Achieving the Honours level has no bearing on the allowed power.
