  2. Using Repeaters Fun on Repeaters

  3. Basic Voice (Phone) Guidelines • Be polite. • Do not interrupt other operators. • Do not hog the frequency. • Listen before you talk. • If someone else is using the frequency, let them have it. Move to another frequency. • Keep it simple. • Speak clearly and slowly. • Use terms people understand. Avoid colloquialisms. • Use the ITU phonetic alphabet to spell when needed. • Use common abbreviations and acronyms. • Use the Correct Sideband. • >14MHz - Use Upper Side Band • Always identify yourself.

  9. T5C02 (pg 89) • What is a courtesy tone? • A tone used to identify the repeater • A tone used to indicate when a transmission is complete • A tone used to indicate that a message is waiting for someone • A tone used to activate a receiver in case of severe weather Fun on Repeaters

  10. T5C03 (pg 89) • Which of the following is the most important information to know before using a repeater? • The repeater input and output frequencies • The repeater call sign • The repeater power level • Whether or not the repeater has an autopatch Fun on Repeaters

  11. T5C07 (pg 90) • What is meant by the terms input and output frequency when referring to repeater operations? • The repeater receives on one frequency and transmits on another • The repeater offers a choice of operating frequencies • One frequency is used to control the repeater and another is used to retransmit received signals • The repeater must receive an access code on one frequency before it will begin transmitting Fun on Repeaters

  12. T5C05 (pg 90) • What is the most common input/output frequency offset for repeaters in the 2-meter band? • 0.6 MHz • 1.0 MHz • 1.6 MHz • 5.0 MHz Fun on Repeaters

  14. T3A02 (pg 90) • How do you call another station on a repeater if you know the station's call sign? • Say "break, break" then say the station's call sign • Say the station's call sign then identify your own station • Say "CQ" three times then the other station's call sign • Wait for the station to call "CQ" then answer it Fun on Repeaters

  15. T9B07 (pg 91) • What is a good thing to remember when using your hand-held VHF or UHF radio to reach a distant repeater? • Speak as loudly as possible to help your signal go farther • Keep your transmissions short to conserve battery power • Keep the antenna as close to vertical as you can • Turn off the CTCSS tone Fun on Repeaters

  16. T9B09 (pg 92) • What might be a way to reach a distant repeater if buildings or obstructions are blocking the direct line of sight path? • Change from vertical to horizontal polarization • Try using a directional antenna to find a path that reflects signals to the repeater • Ask the repeater owners to repair their receiver • Transmit on the repeater output frequency Fun on Repeaters

  17. T9B05 (pg 93) • What should you do if a station reports that your signals were strong just a moment ago, but now they are weak or distorted? • Change the batteries in your radio to a different type • Speak more slowly so he can understand your better • Ask the other operator to adjust his squelch control • Try moving a few feet, random reflections may be causing multipath distortion. Fun on Repeaters

  18. T5D12 (pg 93) • What might be the problem if you receive a report that your signal through the repeater is distorted or weak? • Your transmitter may be slightly off frequency • Your batteries may be running low • You could be in a bad location • All of these answers are correct Fun on Repeaters

  19. T6C09 (pg 93) • 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 Fun on Repeaters

  20. T2B04 (pg 93) • What is an acceptable method of transmitting a repeater station identification? • By phone using the English language • By video image conforming to applicable standards • By Morse code at a speed not to exceed 20 words per minute • All of these answers are correct. Fun on Repeaters

  21. T5C11 (pg 94) • What is the term for a series of repeaters that can be connected to one another to provide users with a wider coverage? • Open repeater system • Closed repeater system • Linked repeater system • Locked repeater system Fun on Repeaters

  22. T5C13 (pg 94) • Which of the following statements regarding use of repeaters is true? • All amateur radio operators have the right to use any repeater at any time • Access to any repeater may be limited by the repeater owner • Closed repeaters must be opened at the request of any amateur wishing to use it • Open repeaters are required to use CTCSS tones for access Fun on Repeaters

  23. T5C14 (pg 94) • What term is used to describe a repeater when use is restricted to the members of a club or group? • A beacon station • An open repeater • A auxiliary station • A closed repeater Fun on Repeaters

  24. T3B05 (pg 95) • What is the main purpose of repeater coordination? • To reduce interference and promote proper use of spectrum • To coordinate as many repeaters as possible in a small area • To coordinate all possible frequencies available for repeater use • To promote and encourage use of simplex frequencies Fun on Repeaters

  25. Repeater Coordination • Frequencies • Locations • Range (i.e., power, antenna, etc.) • Modes Fun on Repeaters

  26. T3B04 (pg 95) • Who is in charge of the repeater frequency band plan in your local area? • The local FCC field office • RACES and FEMA • The recognized frequency coordination body • Repeater Council of America Fun on Repeaters

  33. T3B03 (pg 98) • Who developed the band plans used by amateur radio operators? • The US Congress • The FCC • The amateur community • The Interstate Commerce Commission • Remember: Band plans are voluntary, and we developed them to make life easier for ourselves. Fun on Repeaters

  34. T5C08 (pg 98) • What is the meaning of the term simplex operation? • Transmitting and receiving on the same frequency • Transmitting and receiving over a wide area • Transmitting on one frequency and receiving on another • Transmitting one-way communications • Simplexis traditional walkie-talkie operation: you listen to the signal direct from the other radio. • Repeater: you’re actually listening to a signal retransmitted from a taller, more powerful radio. Fun on Repeaters

  35. T5C09 (pg 99) • What is a reason to use simplex instead of a repeater? • When the most reliable communications are needed • To avoid tying up the repeater when direct contact is possible • When an emergency telephone call is needed • When you are traveling and need some local information Fun on Repeaters

  36. T5C10 (pg 99) • How might you find out if you could communicate with a station using simplex instead of a repeater? • Check the repeater input frequency to see if you can hear the other station • Check to see if you can hear the other station on a different frequency band • Check to see if you can hear a more distant repeater • Check to see if a third station can hear both of you • Press the “REV” (reverse) button. This temporarily swaps the input/output frequencies, so you briefly listen for the other ham on the “input” frequency. Fun on Repeaters
