Your First Radio • The push to talk function which switches between receive and transmit. It’s also called PTT. T 7 A 07 • Storing popular frequencies in a memory channel is a way to enable quick access to favorite frequencies on your transceiver. T 4 B 04 • A disadvantage of the “rubber duck” antenna supplied with most handheld transceivers does not transmit or receive as effectively as a full sized antenna. T 9 A 04 4

Your First Radio • Signals can be significantly weaker when using a handheld inside versus outside due to the shielding effect of your car. T 9 A 07 • An RF power amplifier will increase the low-power output from a handheld transceiver. T 7 A 10 • Frequency modulation (FM) us most commonly used for VHF and UHF repeaters. T 8 A 04 5

Your First Radio • The approximate bandwidth of a VHF repeater FM phone signal is between 10 and 15 k. Hz. T 8 A 09 • The most common type of modulation used for VHF packet radio transmission is FM. T 8 A 02 6

Element 2 Technician Class Question Pool Your First Radio Valid July 1, 2018 Through June 30, 2022 7

T 7 A 07 What is meant by the term “PTT”? A. Pre-transmission tuning to reduce transmitter harmonic emission B. Precise tone transmissions used to limit repeater access to only certain signals C. A primary transformer tuner use to match antennas D. The push to talk function which switches between receive and transmit 8

T 4 B 04 What is a way to enable quick access to a favorite frequency on your transceiver? A. Enable the CTCSS tones B. Store the frequency in a memory channel C. Disable the CTCSS tones D. Use the scan mode to select the desired frequency 9

T 9 A 04 What is a disadvantage of the "rubber duck" antenna supplied with most handheld radio transceivers? A. It does not transmit or receive as effectively as a full-sized antenna B. It transmits a circularly polarized signal C. If the rubber end cap is lost it will unravel very quickly D. All of these choices are correct 10

T 9 A 07 What is a disadvantage of using a handheld VHF transceiver, with its integral antenna, inside a vehicle? A. Signals might not propagate well due to the shielding effect of the vehicle B. It might cause the transceiver to overheat C. The SWR might decrease, decreasing the signal strength D. All of these choices are correct 11

T 7 A 10 What device increases the low-power output from a handheld transceiver? A. B. C. D. A voltage divider An RF power amplifier An impedance network All of these choices is correct 12

T 8 A 04 Which type of modulation is most commonly used for VHF and UHF voice repeaters? A. B. C. D. AM SSB PSK FM 13

T 8 A 09 What is the approximate bandwidth of a VHF repeater FM phone signal? A. B. C. D. Less than 500 Hz About 150 k. Hz Between 10 and 15 k. Hz Between 50 and 125 k. Hz 14

T 8 A 02 What type of modulation is most commonly used for VHF packet radio transmissions? A. B. C. D. FM SSB AM Spread Spectrum 15
