Amateur Radio Question PoolsNew! View the differences between the 2008 Extra question pool and the previous pool. Technician Class Question PoolPrev 1 2 3 4 5 6 7 8 9 0 NextT6A01 What are phone transmissions? The use of telephones to set up an amateur radio contact A phone patch between amateur radio and the telephone system Voice transmissions by radio Placing the telephone handset near a radio transceiver's microphone and speaker to relay a telephone call T6A02 Which of the following is a form of amplitude modulation? Frequency modulation Phase modulation Single sideband Phase shift keying T6A03 What name is given to an amateur radio station that is used to connect other amateur stations to the Internet? A gateway A repeater A digipeater A beacon station T6A04 Which type of voice modulation is most often used for long distance and weak signal contacts on the VHF and UHF bands? FM AM SSB PM T6A05 Which type of modulation is most commonly used for VHF and UHF voice repeaters? AM SSB PSK FM T6A06 Which emission type has the narrowest bandwidth? FM voice SSB voice CW Slow-scan TV T6A07 Which sideband is normally used for VHF and UHF SSB communications? Upper sideband Lower sideband Suppressed sideband Inverted sideband T6A08 What is the primary advantage of single sideband over FM for voice transmissions? SSB signals are easier to tune in than FM signals SSB signals are less likely to be bothered by noise interference than FM signals. SSB signals use much less bandwidth than FM signals SSB signals have no advantages at all in comparison to other modes. T6A09 What is the approximate bandwidth of a single-sideband voice signal? 1 kHz 2 kHz Between 3 and 6 kHz Between 2 and 3 kHz T6A10 What is the approximate bandwidth of a frequency-modulated voice signal? Less than 500 Hz About 150 kHz Between 5 and 15 kHz More than 30 kHz T6A11 What is the normal bandwidth required for a conventional fast-scan TV transmission using combined video and audio on the 70- centimeter band? More than 10 MHz About 6 MHz About 3 MHz About 1 MHz T6B01 How is information transmitted between stations using Echolink? APRS PSK31 Internet Atmospheric ducting T6B02 What does the abbreviation IRLP mean? Internet Radio Linking Project Internet Relay Language Protocol International Repeater Linking Project International Radio Linking Project T6B03 Who may operate on the Echolink system? Only club stations Any licensed amateur radio operator Technician class licensed amateur radio operators only Any person, licensed or not, who is registered with the Echolink system T6B04 What technology do Echolink and IRLP have in common? Voice over Internet protocol Ionospheric propagation AC power lines PSK31 T6B05 What method is used to transfer data by IRLP? VHF Packet radio PSK31 Voice over Internet protocol None of these answers are correct T6B06 What does the term IRLP describe? A method of encrypting data A method of linking between two or more amateur stations using the Internet A low powered radio using infra-red frequencies An international logging program. T6B07 Which one of the following allows computer-to-radio linking for voice transmission? Grid modulation EchoLink AMTOR Multiplex T6B08 What are you listening to if you hear a brief tone and then a station from Russia calling CQ on a 2-meter repeater? An ionospheric band opening on VHF A prohibited transmission An Internet linked DX station None of these answers are correct T6B10 Where might you find a list of active nodes using VoIP? The FCC Rulebook From your local emergency coordinator A repeater directory or the Internet The local repeater frequency coordinator T6B11 When using a portable transceiver how do you select a specific IRLP node? Choose a specific CTCSS tone Choose the correct DSC tone Access the repeater autopatch Use the keypad to transmit the IRLP node numbers T6C01 Which of the following is an example of a digital communications method? Single sideband voice Amateur television FM voice Packet radio T6C02 What does the term APRS mean? Automatic Position Reporting System Associated Public Radio Station Auto Planning Radio Set-up Advanced Polar Radio System T6C03 What item is required along with your normal radio for sending automatic location reports? A connection to the vehicle speedometer A connection to a WWV receiver A connection to a broadcast FM sub-carrier receiver A global positioning system receiver T6C04 What type of transmission is indicated by the term NTSC? A Normal Transmission mode in Static Circuit A special mode for earth satellite uplink A standard fast scan color television signal A frame compression scheme for TV signal T6C05 What emission mode may be used by a Technician class operator in the 219 - 220 MHz frequency range? Slow-scan television Point-to-point digital message forwarding FM voice Fast-scan television T6C06 What does the abbreviation PSK mean? Pulse Shift Keying Phase Shift Keying Packet Short Keying Phased Slide Keying T6C07 What is PSK31? A high-rate data transmission mode used to transmit files A method of reducing noise interference to FM signals A type of television signal A low-rate data transmission mode that works well in noisy conditions T6C08 What sending speed is recommended when using Morse code? Only speeds below five WPM The highest speed your keyer will operate Any speed at which you can reliably receive The highest speed at which you can control the keyer T6C09 What is a practical reason for being able to copy CW when using repeaters? To send and receive messages others cannot overhear To conform with FCC licensing requirements To decode packet radio transmissions To recognize a repeater ID sent in Morse code T6C10 What is the "Q" signal used to indicate that you are receiving interference from other stations? QRM QRN QTH QSB T6C11 What is the "Q" signal used to indicate that you are changing frequency? QRU QSY QSL QRZ |
