G4D01:

What is the purpose of a speech processor as used in a modern transceiver?

  1. Increase the intelligibility of transmitted phone signals during poor conditions
  2. Increase transmitter bass response for more natural-sounding SSB signals
  3. Prevent distortion of voice signals
  4. Decrease high-frequency voice output to prevent out-of-band operation

G4D02:

Which of the following describes how a speech processor affects a transmitted single sideband phone signal?

  1. It increases peak power
  2. It increases average power
  3. It reduces harmonic distortion
  4. It reduces intermodulation distortion

G4D03:

Which of the following can be the result of an incorrectly adjusted speech processor?

  1. Distorted speech
  2. Splatter
  3. Excessive background pickup
  4. All these choices are correct

G4D04:

What does an S meter measure?

  1. Conductance
  2. Impedance
  3. Received signal strength
  4. Transmitter power output

G4D05:

How does a signal that reads 20 dB over S9 compare to one that reads S9 on a receiver, assuming a properly calibrated S meter?

  1. It is 10 times less powerful
  2. It is 20 times less powerful
  3. It is 20 times more powerful
  4. It is 100 times more powerful

G4D06:

Where is an S meter found?

  1. In a receiver
  2. In an SWR bridge
  3. In a transmitter
  4. In a conductance bridge

G4D07:

How much must the power output of a transmitter be raised to change the S meter reading on a distant receiver from S8 to S9?

  1. Approximately 1.5 times
  2. Approximately 2 times
  3. Approximately 4 times
  4. Approximately 8 times

  2. 14.347 to 14.350 MHz
  3. 14.344 to 14.347 MHz
  4. 14.3455 to 14.3485 MHz

  2. At least 3 kHz below the edge of the band
  3. At least 1 kHz above the edge of the segment
  4. At least 1 kHz below the edge of the segment
