The Fun Part

  • World-wide High Frequency Comm.
  • Local VHF/UHF FM and repeaters
  • It can be used at home
  • You can take it with you:

– Mobile – Handheld

World-wide radio

  • How it works:
  • High Frequency (Shortwave) Radio

– Skip: the Ionosphere (Mother Nature’s Internet server) – Look Ma – no wires!

World-wide radio

  • Language Barrier?

– English is very common, but not everyone speaks it, even in ham radio – CW is a common language, but no longer required by ITU & some Administrations – ITU ‘Q’ signals is a common language

9 November 12

slide-10
SLIDE 10

What do hams talk about?

  • Radio

– transmitter/receiver equipment – transmitter power – antenna – location (QTH) – radio technology – everything else

Amateurs in space

  • Our own satellites – lot’s of ‘em
  • On the space shuttles since 1983
  • First “ham in space” – astronaut

Amateurs in space

  • Today, a full-time ham station on the ISS

Hams in space

  • Most astronauts are licensed hams, including

the three currently on the ISS, and three of the astronauts who died

  • n Columbia.
  • SAREX:

Hams in space talk to kids on Earth.

Antennas

  • Some hard realities:
  • Big antennas up high

work better than little antennas down low

  • Everyone prefers little

antennas

16 November 12

slide-17
SLIDE 17

Antennas

  • for example: this 2000 foot

tower supports:

  • WRAL and WRDC TV
  • 6 FM broadcast stations
  • many commercial and public-

safety repeaters

  • 6 amateur radio repeaters

17 November 12

slide-18

Antennas

  • A plug for cell phone towers:

– They have to be somewhere… – … nearby, or – the phone doesn’t work!

slide-21
SLIDE 21

Our Nemesis:

  • Deed restrictions, aka CC&R’s
  • Homeowner’s Associations (HOAs)
  • Restrictions, outright prohibition of

antennas, transmitting

  • “Antenna friendly” neighborhoods are hard

to find!

  • Sometimes, state and local governments

21 November 12

slide-22
SLIDE 22

Our other evil….

  • RFI: Radio Frequency Interference,

Typically to:

– TVs – Phones – Audio systems

22 November 12

slide-23
SLIDE 23

What to do:

  • (the short course – this is a half-hour

presentation later in the course!)

– Contact the ham… – Diagnose the problem – Contact the manufacturer and/or vendor – Install filters

Emergency & public service

  • Our unique capabilities include:

– trained volunteers – communications “Off The Grid” – generator and battery power – no phone lines, no Internet – from anywhere, to anywhere (almost)

25 November 12

slide-26
SLIDE 26

Emergency & public service

  • When the power goes out and the

phones go dead . . .Hams are there

– Hurricanes – Floods – Fires – Earthquakes – Tornados

Emergency & public service

  • When the power goes out and the phones go

dead . . .

– hurricanes – floods – ice storms – tornados – earthquakes – fires

Emergency Operation Centers

  • county EOCs
  • command posts
  • shelters
  • in the field
  • State EOCs

Amateurs and public service

  • Event support:

– bike tours – Walks – Field days

  • Shadow officials
  • Rest stops
  • Medical teams

Amateur Field Day

(Emergency communications practice)

  • usually a weekend
  • 24 hour emergency

exercise/contest

  • totally off the

“grid” (power)

  • public is welcome

31 November 12

slide-32
SLIDE 32

Some times athletic?

  • Amateur radio DFing, or

‘Fox Hunting’

  • Combines orienteering

with radio direction finding

  • No license needed

32 November 12

slide-33
SLIDE 33

Where did the word “Ham” come from?

  • We don’t know for sure
  • In the late 1800s railroad telegraphers called the

new guys “hams” or “ham-fisted”

  • Early radio was all telegraphy
  • Commercial operators came from the railroad

telegraphers

  • They probably called the amateurs “hams”
  • We take it as a compliment!

33 November 12

SLIDE 34

Becoming a Ham

3 Classes of licenses:  Technician – no Morse code

– entry level exam, electronics,

  • peration, safety, FCC regs

 General - no Morse code – tougher exam  Amateur Extra - no Morse code – toughest exam

34 November 12

slide-35
SLIDE 35

Becoming a Ham

  • Local classes
  • Internet classes
  • Elmers
  • Self study

– Technician license in about six weeks

35 November 12

slide-36
SLIDE 36

Amateur’s Competition

  • Internet and cell phones
  • video games
  • growing slowly; about 650,000 + US hams,

about 2.5 million worldwide

  • average age creeping up

36 November 12

slide-37
SLIDE 37

The ham advantage

  • We are still more “mobile” – for now
  • We keep working when the phones and

power quits

  • We have more fun!
  • Ham radio is not for everyone
