    Practice


    B-003-14-01
    What do many amateurs use to help form good Morse code characters?
    An electronic keyer
    A key-operated on/off switch
    A notch filter
    A DTMF keypad

    B-003-14-02
    Where would you connect a microphone for voice operation?
    To a transceiver
    To a power supply
    To an antenna switch
    To an antenna

    B-003-14-03
    What would you connect to a transceiver for voice operation?
    A receiver audio filter
    A terminal-voice controller
    A microphone
    A splatter filter

    B-003-14-04
    Why might a dummy antenna get warm when in use?
    Because it absorbs static electricity
    Because it stores radio waves
    Because it changes RF energy into heat
    Because it stores electric current

    B-003-14-05
    What is the circuit called which causes a transmitter to automatically transmit when an operator speaks into its microphone?
    VXO
    VCO
    VFO
    VOX

    B-003-14-06
    What is the reason for using a properly adjusted speech processor with a singlesideband phone transmitter?
    It improves signal intelligibility at the receiver
    It reduces average transmitter power requirements
    It reduces unwanted noise pickup from the microphone
    It improves voice frequency fidelity

    B-003-14-07
    If a single-sideband phone transmitter is 100% modulated, what will a speech processor do to the transmitter's power?
    It will add nothing to the output PEP
    It will increase the output PEP
    It will decrease the peak power output
    It will decrease the average power output

    B-003-14-08
    When switching from receive to transmit:
    the receiver should be muted
    the transmit oscillator should be turned off
    the receiving antenna should be connected
    the power supply should be off

    B-003-14-09
    A switching system to enable the use of one antenna for a transmitter and receiver should also:
    ground the antenna on receive
    disable the unit not being used
    switch between meters
    disconnect the antenna tuner

    B-003-14-10
    An antenna changeover switch in a transmitter-receiver combination is necessary:
    so that one antenna can be used for transmitter and receiver
    to change antennas for operation on other frequencies
    to prevent RF currents entering the receiver circuits
    to allow more than one transmitter to be used

    B-003-14-11
    Which of the following components could be used as a dynamic microphone?
    crystal earpiece
    resistor
    loudspeaker
    capacitor
