  1. You are mobile and talking through a VHF repeater. The other station reports that you keep "dropping out". This means:
    1. your signal is drifting lower in frequency
    2. your signal does not have enough strength to operate the repeater
    3. your voice is too low-pitched to be understood
    4. you are not speaking loudly enough

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

  3. The question "Who is calling me?" is asked by:
    1. QRT?
    2. QRM?
    3. QRP?
    4. QRZ?

  4. A damaged antenna or feedline attached to the output of a transmitter will present an incorrect load resulting in:
    1. the driver stage not delivering power to the final
    2. the output tuned circuit breaking down
    3. excessive heat being produced in the transmitter output stage
    4. loss of modulation in the transmitted signal

  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. Magnetic and electric fields about an antenna are:
    1. parallel to each other
    2. determined by the type of antenna used
    3. perpendicular to each other
    4. variable with the time of day

  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
