  1. The "S meter" on a receiver:
    1. indicates where the squelch control should be set
    2. indicates the standing wave ratio
    3. indicates the state of the battery voltage
    4. indicates relative incoming signal strengths

  2. The term "ALC" stands for:
    1. audio limiter control
    2. automatic level control
    3. automatic loudness control
    4. automatic listening control

  3. The "Q" signal "your signals are fading" is:
    1. QSO
    2. QSB
    3. QSL
    4. QRX

  4. The designed output impedance of the antenna socket of most modern transmitters is nominally:
    1. 25 ohm
    2. 50 ohm
    3. 75 ohm
    4. 100 ohm

  5. A result of standing waves on a non-resonant transmission line is:
    1. maximum transfer of energy to the antenna from the transmitter
    2. perfect impedance match between transmitter and feedline
    3. reduced transfer of RF energy to the antenna
    4. lack of radiation from the transmission line

  6. In this diagram the item X corresponds to the:
    1. boom
    2. reflector
    3. director
    4. driven element

  7. The effect of adding a series inductance to an antenna is to:
    1. increase the resonant frequency
    2. have no change on the resonant frequency
    3. have little effect
    4. decrease the resonant frequency
