Broadcast Radio
  • Radio transmission which is one-way, and intended
    for reception by the general public

8
Two-Way Radio
  • Radio which both transmits and receives (two-way)
  • Police / fire
  • Utilities
  • Businesses
  • Cellular

9
Amateur Radio
  • A volunteer non-commercial radio service devoted
    to educational, recreational and emergency
    purposes
  • Ham Radio
  • Hobby Radio

  • Transmitter - Generates radio frequency (RF)
    signal
  • Amplifier - Makes the signal stronger and drives
    feed line
  • Antenna - Launches the electromagnetic wave into
    the air

18
Modulation
  • Modulation Superimposing information (audio,
    data, video) onto a radio signal

Un-modulated radio carrier
Carrier modulated with audio
19
How radio signals carry information
  • Continuous Wave (CW or Morse Code)
  • Amplitude Modulation (AM)
  • Frequency Shift-Keying (FSK Examples Radio

Radio Propagation Characteristics
  • HF Wavelengths (160 10 meters)
  • Generally utilizes skywave propagation
  • Affected by solar activity
  • VHF Wavelengths (6 meters 2 meters)
  • Generally utilize line-of-sight
  • Affected very little by solar activity
  • UHF Wavelengths (70cm and shorter)
  • Generally utilize light-of-sight propagation
  • Affected much by terrain, buildings

22
Radio Station WWV
2.5, 5, 10, 15 and 20 Mhz
  • Transmits on standard frequencies
  • If you can hear WWV, the HF bands are open

Fort Collins, CO
23
Broadband Over Power Lines (BPL)
  • Sends internet signals down open power lines
  • Pollutes radio frequencies between 1.7 and 80 Mhz
  • Over 59,000 federal government radio systems in
    affected frequency bands
  • Speeds of 300k to 1 Mbps (near DSL speed, but is
    shared connection)

24
WiMax The Superior Technology
Popular Mechanics, Dec 2004, p30
  • Non-polluting because it has its own frequencies
    (2500 to 2900 Mhz)
  • Currently being built on existing cell towers
  • Fixed range (cell tower to home of office) up to
    30 miles 70 Mbps
  • Mobile coverage same as ordinary cell coverage 1
    to 4 Mbps
  • Can hand-over data stream as you travel at
    highway speeds up to 60 MPH

Basic Electrical Terms
  • Conductor substance through which electricity
    flows easily (copper, silver, gold)
  • Insulator substance through which electricity
    does not flow easily (glass, rubber, plastic)

30
Types of Electrical Current
  • Direct Current (DC) flows only one direction
    produced by battery
  • Alternating Current (AC) flows in first one
    direction then another found in our home
    electrical outlets

31
Basic Electrical Terms
  • Voltage electrical pressure (volts)
  • Current the flow of electricity through a
    circuit (amps)

Safety With RF Energy
  • Never operate radios with the cover off
  • Exposure to high levels of RF can cause burns and
    cancer
  • Human eyes especially sensitive to RF
  • Hams required to conduct a routine station
    evaluation to verify safe operation (usually
    done by consulting a chart)

41
Safety With Electricity
  • Minimum fatal voltage 30 volts
  • Minimum fatal current if passed through the human
    heart 1/10th of an amp
  • Power lines are un-insulated and carry thousands
    of volts never touch them!

Boy Meets Power Lines
  • Boys Arms Amputated After Shock From Cable
  • GENOA, Ark. Doctors amputated both arms of a
    13-year-old boy below the elbow after he
    sustained a shock from an electrical distribution
    cable. David Letterman, 13, of Genoa underwent
    surgery at Arkansas Childrens Hospital, his
    family said. David and his friend, Cody Sims,
    11, were walking a power line right-of-way with
    the idea of bow hunting before church when they
    came upon a tree that had fallen on an electrical
    cable. David wanted to remove the dead tree from
    the line because he saw it smoking and was afraid
    it would catch fire.

If Power Lines Strike Your Car
  • Stay inside and call for help
  • Power lines can re-energize automatically. Never
    assume they are dead.
  • If car catches fire, jump out on both feet and
    scoot away.

61
Antennas Towers
  • Never place antennas or feed lines
  • OVER or UNDER power lines
  • Where they could fall on a power line in any
    direction
  • Where a person could touch the antenna

62
Lightning Protection
  • Antenna pole connected to ground rod
  • Disconnect radios if lightning is in the area
  • Disconnect radios when not in use
  • Connect antennas to ground when not in use

63
Grounding Your Station
Common ground point Fuse or circuit breaker
Safety interlock on high voltage supplies
Everyone in your house should know how to shut
off the power
64
Hybrid Cars
  • Main batteries - 200 to 300 volts DC at hundreds
    of amps
  • With car switched on, main power lines carry 300
    to 600 volts AC, three phase

  • Requires some practice
  • Cost - 300 and up

89
Global Positioning System (GPS)
  • 24 orbiting satellites transmit signals on the
    1700 Mhz band
  • Satellites cannot track a person they only
    send signals down

90
Global Positioning System (GPS)
  • Handheld GPS receiver shows Lat / Long reading
    accurate to within a few yards
  • Could be shut down in extreme national emergency
  • Cost - 100 and up

91
Global Positioning System (GPS)
From the BSA Field Book, page 78
Global positioning system (GPS) receivers allow
travelers to pinpoint their locations, but they
are no substitute for mastering the use of maps
and compasses.
Your greatest emergency preparedness tool is
your mind. You still need to take the
Orienteering class
92
Family Radio Service (FRS)
  • FRS is a radio service in the UHF band for use by
    the general public.
  • 14 channels ½ watt of output power

Cell Phones In The Wilderness
From the BSA Field Book, page 78
Likewise, wireless telephones can be a
convenient means for groups to contact emergency
response personnel, but phones are useless if
they malfunction, the batteries are exhausted, or
distance and terrain prevent clear reception of
signals. Frivolous use of wireless phones
can seriously diminish solitude, independence,
and challenge in the outdoors. If you carry a
portable telephone, stow it deep in your pack and
bring it out only for emergency calls.
97
Cell Phones In The Wilderness
  • Music Player

BSA Field Book, p78
  • Idle Chit-Chat
  • Video Game
  • Emergency preparedness tool
  • Keep packed away and
  • turned off
  • Carry extra battery
  • Respect serenity of outdoors
  • Just because Scoutmaster has one doesnt mean
    YOURE prepared!

98
Cell Phones In The Wilderness
From the chapter entitled Avoiding the Outdoor
Emergency
Know how to increase your phones signal
strength by pointing the antenna up, moving into
a clearing, gaining elevation, and turning your
body (you might be obstructing the signal)cell
phones should never replace preparedness.
Wilderness Survival Merit Badge Book, p 15
99
That Old Cell Phone
  • Dont throw away your old cell phones
  • Any Cell Phone Can Reach 911-even one thats not
    activated
  • Weakness 911 operator may not be able to call
    you back if you get disconnected during a call

101
Cellular During a Disaster
  • Weakness
  • During widespread emergency, Such as 9-11 or the
    2005 London train bombings, cell systems busy out
    and become unusable.

102
Cellular During a Disaster
Lighten The Load On The System
  • PTT Call
  • More efficient use of resources because it allows
    you to talk with multiple people at once
  • Text Message
  • Will get through when a voice call wont because
    its a quick data burst

103
Cellular During a Disaster
  • Voice calls would not get through when cell
    system jammed
  • Text messages got through

104
Dialing 911 From a Cell Phone
  • Your cell site gets a directional and distance
    fix, then nearby sites do the same
  • If your phone has GPS, your lat / long is reported
  • Map of your location appears on 911 operators
    screen

Your site
  • Entire position fix process takes 15 to 30 seconds
