Topic T2B Quick Review Audio


What is the most common use of the "reverse split" function of a VHF/UHF transceiver?

  1. Reduce power output
  2. Increase power output
  3. Listen on a repeater's input frequency
  4. Listen on a repeater's output frequency


What term describes the use of a sub-audible tone transmitted along with normal voice audio to open the squelch of a receiver?

  1. Carrier squelch
  2. Tone burst
  3. DTMF
  4. CTCSS


If a station is not strong enough to keep a repeater's receiver squelch open, which of the following might allow you to receive the station's signal?

  1. Open the squelch on your radio
  2. Listen on the repeater input frequency
  3. Listen on the repeater output frequency
  4. Increase your transmit power


Which of the following could be the reason you are unable to access a repeater whose output you can hear?

  1. Improper transceiver offset
  2. The repeater may require a proper CTCSS tone from your transceiver
  3. The repeater may require a proper DCS tone from your transceiver
  4. All of these choices are correct


What might be the problem if a repeater user says your transmissions are breaking up on voice peaks?

  1. You have the incorrect offset
  2. You need to talk louder
  3. You are talking too loudly
  4. Your transmit power is too high


What type of tones are used to control repeaters linked by the Internet Relay Linking Project (IRLP) protocol?

  1. DTMF
  2. CTCSS
  3. EchoLink
  4. Sub-audible


How can you join a digital repeater's "talk group"?

  1. Register your radio with the local FCC office
  2. Join the repeater owner's club
  3. Program your radio with the group's ID or code
  4. Sign your call after the courtesy tone


Which of the following applies when two stations transmitting on the same frequency interfere with each other?

  1. Common courtesy should prevail, but no one has absolute right to an amateur frequency
  2. Whoever has the strongest signal has priority on the frequency
  3. Whoever has been on the frequency the longest has priority on the frequency
  4. The station that has the weakest signal has priority on the frequency


What is a "talk group" on a DMR digital repeater?

  1. A group of operators sharing common interests
  2. A way for groups of users to share a channel at different times without being heard by other users on the channel
  3. A protocol that increases the signal-to-noise ratio when multiple repeaters are linked together
  4. A net that meets at a particular time


Which Q signal indicates that you are receiving interference from other stations?

  1. QRM
  2. QRN
  3. QTH
  4. QSB


Which Q signal indicates that you are changing frequency?

  1. QRU
  2. QSY
  3. QSL
  4. QRZ


Why are simplex channels designated in the VHF/UHF band plans?

  1. So that stations within mutual communications range can communicate without tying up a repeater
  2. For contest operation
  3. For working DX only
  4. So that stations with simple transmitters can access the repeater without automated offset


Where may SSB phone be used in amateur bands above 50 MHz?

  1. Only in sub-bands allocated to General class or higher licensees
  2. Only on repeaters
  3. In at least some portion of all these bands
  4. On any band as long as power is limited to 25 watts


Which of the following describes a linked repeater network?

  1. A network of repeaters where signals received by one repeater are repeated by all the repeaters
  2. A repeater with more than one receiver
  3. Multiple repeaters with the same owner
  4. A system of repeaters linked by APRS
