To reduce harmonic output from a transmitter you would put
a _______ in the transmission line as close to the transmitter as possible.:
  1. wave trap 2. low pass filter 3. high pass filter 4. band reject filter

Which of the following components could be used as a dynamic microphone:
1. loudspeaker 2. capacitor 3. resistor 4. crystal oscillator operating on its fundamental

When measuring current drawn by a light bulb from a dc
supply, it is true to say that the meter will act in the circuit as:
1. an insulator 2. a low value resistance 3. a perfect conductor 4. an extra current drain

Which of the following meters would you use to measure the power
supply current drawn by a small handheld transistorized receiver:
1. power meter 2. an RF ammeter 3. a moving coil ammeter 4. an electrostatic voltmeter

FM repeater operations on VHF uses one frequency for transmission and one for reception. The difference in frequency between the transmit and receive channel is normally:
1. 400 khz 2. 600 khz 3. 800 khz 4. 1000 khz

When operating CW you should:
1. listen to the frequency to make sure that it is not in use before transmitting 2. tune the transmitter using the operating antenna 3. always give stations good readability reports 4. save time by leaving out spaces between words

The purpose of a dummy antenna is to:
1. reduce the possibility of frequency instability 2. load a transmitter for testing without radiation of signals 3. reduce the possibility of TVI when working other stations within a 50 mi. radius 4. be used in conjunction with a wavemeter for frequency measurements

When switching from receive to transmit:
1. the receiver should be muted 2. The transmit oscillator should be damped 3. the antenna should be connected 4. the power supply should be off

You are transmitting on 2 metres using FM. Several stations advise you that your transmission is distorted. A quick check of the frequency counter tells you that the transmitter is on proper frequency. Which of the following is the most probable cause of the distortion:
1. The frequency counter is giving an incorrect reading and you are indeed off frequency 2. the power supply output voltage is low 3. the repeater is reversing your sidebands 4. the frequency deviation of your transmitter is set too high

To increase the level of very weak radio signals from an antenna, you would use:
1. an audio amplifier 2. an RF amplifier 3. an audio oscillator 4. an RF oscillator
