What can you do if you are told your FM handheld or mobile transceiver is over-deviating?

1. A Talk louder into the microphone
2. B Let the transceiver cool off
3. C Change to a higher power level
4. D Talk farther away from the microphone

What would cause a broadcast AM or FM radio to receive an amateur radio transmission unintentionally?

1. A The receiver is unable to reject strong signals outside the AM or FM band
2. B The microphone gain of the transmitter is turned up too high
3. C The audio amplifier of the transmitter is overloaded
4. D The deviation of an FM transmitter is set too low

Which of the following can cause radio frequency interference?

1. A Fundamental overload
2. B Harmonics
3. C Spurious emissions
4. D All these choices are correct

Which of the following might be the cause of low RF power output from a solid-state transceiver?

1. A Poor amplifier noise figure
2. B Poor amplifier linearity
3. C Low SWR
4. D High SWR

Which of the following might reduce interference by an amateur station to a non-amateur over-the-air radio receiver?

1. A Block the amateur signal with a filter at the antenna input of the affected receiver
2. B Block the interfering signal with a filter on the amateur transmitter
3. C Switch the transmitter from FM to SSB
4. D Switch the transmitter to a narrow-band mode

Which of the following actions should you take if a neighbor tells you that your station's transmissions are interfering with their radio or TV reception?

1. A Make sure that your station is functioning properly and that it does not cause interference to your own radio or television when it is tuned to the same channel
2. B Immediately turn off your transmitter and contact the nearest FCC office for assistance
3. C Install a harmonic doubler on the output of your transmitter and tune it until the interference is eliminated
4. D All these choices are correct

Which of the following can reduce interference to a 2-meter band transceiver from a nearby commercial FM station?

1. A Installing an RF preamplifier
2. B Using double-shielded coaxial cable
3. C Installing bypass capacitors on the microphone cable
4. D Installing a band-reject filter

What should you do if something in a neighbor's home is causing harmful interference to your amateur station?

1. A Work with your neighbor to identify the offending device
2. B Politely inform your neighbor that FCC rules prohibit the use of devices that cause interference
3. C Make sure your station meets the standards of good amateur practice
4. D All these choices are correct

What should be the first step to resolve non-fiber optic cable TV interference caused by your amateur radio transmission?

1. A Add a low-pass filter to the TV antenna input
2. B Add a high-pass filter to the TV antenna input
3. C Add a preamplifier to the TV antenna input
4. D Be sure all TV feed line coaxial connectors are installed properly

What might be a problem if you receive a report that your audio signal through an FM repeater is distorted or unintelligible?

1. A Your transmitter is slightly off frequency
2. B You are speaking too loudly or too close to the microphone
3. C You are in a bad location
4. D All these choices are correct

Which of the following can eliminate distorted voice transmissions?

1. A Adding extra feedline to the antenna to lower SWR
2. B Turning the radio on and off to reset the computer-controlled circuitry
3. C Adding a clip-on ferrite "choke" to the microphone cable to prevent the transmitted signal from feeding back into the transmitter
4. D Turning the squelch control fully clockwise to prevent the transmitted signal from triggering the squelch circuit
