Patch ordering info
  • Badge and Patch Activity
  • Presented by
  • Mark Spencer, WA8SME

Overview
  • Junior Girl Scout Amateur Radio Patch
  • The who, what, how, and fun of Amateur Radio
  • How radio waves travel
  • Use of codes to expedite communication
  • Cadette or Senior Girl Scout Amateur Radio Patch
  • Journey inside of a radio
  • Open, closed, and short circuitsa shocking
    experience
  • Call signsradio names
  • On-the-air

3
What is Amateur (Ham) Radio?
  • FUN

4
What is Amateur (Ham) Radio(government
definition)
  • Amateur Radio is a radio communications service
    for the purpose of self-training,
    intercommunication and technical investigations
    carried out by amateurs, that is authorized
    persons interested in radio technique solely with
    a personal (non-business) aim.
  • FCC Rules Part 97.3

5
Ham Radio Operators
  • Come from all walks of life young and old, boys
    and girls without regard to ability.
  • Shared interest in many things including
  • Communicating and meeting new people
  • Talking to new places around the world, around
    the block, or in space
  • Science and technology
  • Computers
  • Community service and helping others
  • Competitions
  • Learning new things and applying what you learn

6
How Do I Become a Ham?
  • Takes a few hours to study for a Ham Radio
    Operators exam
  • Study by yourself, with a group, or both
  • Books are available that have all the information
    you need, INCLUDING THE EXAM QUESTIONS
  • The entry level (Technician) exam is 35
    questions, multiple choice
  • Exams are given frequently in this area
  • When you pass the exam (and you will), the FCC
    will issue you your own, unique radio nameyour
    call sign

7
Local Radio Clubs
  • Newington Amateur Radio League (NARL)
  • The local Ham Radio club that meets once a month
  • Participates in community activities and events
  • Holds Ham Radio classes throughout the year
  • Connecticut Amateur Radio League of Youth (CARL)
  • Ham club who's members are primarily young Ham
    Radio Operators
  • Participates in community activities and events
  • Conducts a weekly net (on-the-air gathering for
    chat)
  • Have their own club call sign K3KID
  • American Radio Relay League (ARRL)
  • National organization that supports Ham Radio

The Journey Inside a Radio
  • Major Radio Station Components
  • Transceiver
  • Transmitter
  • Receiver
  • Antenna
  • Antenna feed line
  • Input device
  • Microphone
  • Telegraph key
  • Computer
  • TV camera

Basic Electricity
  • The fundamental principle of electronics
  • Moving electrons create a magnetic field
  • Changing magnetic fields cause electrons to move
  • Electronics is how we manipulate moving electrons
    to create the desired effect

21
The Three Parts of Electricity
  • Voltage
  • Current
  • Resistance

22
The Three Parts are Related by Ohms Laws
  • Voltage E
  • Current I
  • Resistance R
  • Ohms law is the most important relationship
    (formula) in electronics

23
Two Types of Electric Current
  • Direct Current
  • Electrons flow in only one direction
  • Batteries
  • Alternating Current
  • Electrons flow back and forth in a conductor
  • Electricity from your wall sockets

24
Electronic Circuits(pathways for electrons)
  • Complete (Closed)
  • Proper circuit to cause electrons to do something
    useful
  • Short
  • Direct path that bypasses a portion of a circuit
    (usually a bad/dangerous thing)
  • Open
  • A broken circuit with no completed pathway for
    electrons (usually a safety condition)

25
ElectronicSchematics
  • Roadmaps of the inside of a radio
  • Used to build, trouble- shoot, and repair
    electronics

26
The Resistor
  • The component that impedes or restricts the flow
    of electrons in a circuit

27
The Capacitor
  • The component that acts like a very small
    battery. The capacitor temporarily stores energy
    in an electrostatic field between two metal plates

28
The Inductor
  • The component that stores energy by creating a
    magnetic field. The inductor is a coil of wire

29
The Transistor
  • Think of the transistor as an electronic valve
    that we use to control the flow of electrons

30
The Vacuum Tube
  • The predecessor of the transistor. Also a valve
    used to control the flow of electrons.
  • Not very energy efficient, used a lot of energy
    in heat
  • Some tubes still in use today (your computer/TV
    monitor)

31
Switches
  • Many kinds and types of switches. Opens and
    closes a circuit to either stop or allow the
    follow of elections.
  • Here a just a few symbols for various switches

32
Integrated Circuits
  • Integrated means to place together
  • Integrated circuits are collections of electronic
    components put together to do a particular task

36
Operating a Ham Radio Station
  • Calling any station CQ
  • Talk like you normally would exceptonly one
    person can talk at a time, that is called half
    duplex
  • Non Ham Operators talking on the radio is called
    third party trafficsome minor restrictions
  • Give your station call sign each 10 minutes
  • Contacts will be logged (recorded) so that QSL
    cards can be issued if requested

37
Operating a Ham Radio Station
  • Dont be afraid to talk, you wont break
    anything!
  • Have fun meeting new peopleacross the street,
    around the world, or in space
  • Ham Radio
