  3. Amateur Radio Technician ClassElement 2 Course Presentation ELEMENT 2 SUB-ELEMENTS (Groupings) Talk to Outer Space! Your Computer Goes Ham Digital! Multi-Mode Radio Excitement Run Some Interference Protection Electrons – Go With the Flow! It’s the Law, per Mr. Ohm! Go Picture These! Antennas Feed Me With Some Good Coax! Safety First! 3

  4. Your First Radio The push to talk function which switches between receive and transmit. It’s also called PTT.T7A07 Storing popular frequencies in a memory channel is a way to enable quick access to favorite frequencies on your transceiver.T4B04 A disadvantage of the “rubber duck” antenna supplied with most handheld transceivers does not transmit or receive as effectively as a full sized antenna. T9A04 4

  5. Your First Radio Signals can be significantly weaker when using a “rubber duck” antenna inside versus outside your car. T9A07 An RF power amplifier will increase the low-power output from a handheld transceiver. T7A10 Frequency modulation (FM) us most commonly used for VHF and UHF repeaters.T8A04

  6. Your First Radio The approximate bandwidth of a VHF repeater FM phone signal is between 10 and 15 kHz. T8A09 The amplitude of the modulating signal will determine the amount of deviation of an FM (as opposed to PM) signal. T2B05 When the deviation of an FM transmitter is increased its signal output occupies more bandwidth. T2B06 6

  7. Your First Radio The most common type of modulation used for VHF packet radio transmission is FM. T8A02 Computers might be used as part of an amateur radio station: For logging contacts and contact information For sending and/or receiving CW For generating and decoding digital signals All of these choices are correctT4A02 7

  8. Element 2 Technician Class Question Pool Your First Radio Valid July 1, 2014 Through June 30, 2018

  9. T7A07What is meant by the term “PTT”? Pre-transmission tuning to reduce transmitter harmonic emission Precise tone transmissions used to limit repeater access to only certain signals A primary transformer tuner use to match antennas The push to talk function which switches between receive and transmit

  10. T4B04What is a way to enable quick access to a favorite frequency on your transceiver? • Enable the CTCSS tones • Store the frequency in a memory channel • Disable the CTCSS tones • Use the scan mode to select the desired frequency

  11. T9A04What is a disadvantage of the "rubber duck" antenna supplied with most handheld radio transceivers? • It does not transmit or receive as effectively as a full-sized antenna • It transmits a circularly polarized signal • If the rubber end cap is lost it will unravel very quickly • All of these choices are correct

  12. T9A07What is a good reason not to use a "rubber duck" antenna inside your car? • Signals can be significantly weaker than when it is outside of the vehicle • It might cause your radio to overheat • The SWR might decrease, decreasing the signal strength • All of these choices are correct

  13. T7A10What device increases the low-power output from a handheld transceiver? • A voltage divider • An RF power amplifier • An impedance network • All of these choices is correct

  14. T8A04Which type of modulation is most commonly used for VHF and UHF voice repeaters? • AM • SSB • PSK • FM

  15. T8A09What is the approximate bandwidth of a VHF repeater FM phone signal? • Less than 500 Hz • About 150 kHz • Between 10 and 15 kHz • Between 50 and 125 kHz

  16. T2B05What determines the amount of deviation of an FM (as opposed to PM) signal? Both the frequency and amplitude of the modulating signal The frequency of the modulating signal The amplitude of the modulating signal The relative phase of the modulating signal and the carrier

  17. T2B06What happens when the deviation of an FM transmitter is increased? Its signal occupies more bandwidth Its output power increases Its output power and bandwidth increases Asymmetric modulation occurs

  18. T8A02What type of modulation is most commonly used for VHF packet radio transmissions? • FM • SSB • AM • Spread Spectrum

  19. T4A02How might a computer be used as part of an amateur radio station? • For logging contacts and contact information • For sending and/or receiving CW • For generating and decoding digital signals • All of these choices are correct
