History of the first Internet
  • Marconi
  • Father of wireless
  • Amateur Radio Relay League (ARRL) and Amateurs in
    general
  • Amateur Radio Operators (cutting edge of
    technology) with a goal
  • Internet of today
  • Al Gore invented this one!

3
Modes of Operation
  • Digital Modes
  • Radio teletype
  • Packet
  • Packtor
  • Amtor
  • Clover
  • PSK 32

4
Uses Of Computers InHam Radio Today
  • Database (callbook automation)
  • Client Server
  • Logbook of the world (ARRL feature)
  • Local databases and programs (i.e., log-eqf)
  • Lots of free software and features like
  • Callbook lookup (CD ROM) when callsign entered
  • Short/long path direction from geographic
    location
  • Contest logging and calculations
  • Minimum requirements of FCC met
  • OSCAR locating (Kiplerean elements)

  • Started out as a voice chat and later added
    xmitters at the computer.
  • Still in use with just the computers, but also
    accessible to trojans, hackers, etc.

IRLP
  • IRLP (Internet Radio Linking Project)
  • Uses a dedicated transmitter, connected to a
    dedicated computer (Linux), connected to a
    broadband internet connection
  • A simple hand held transceiver, transmits on the
    IRLP frequency, and the IRLP node receives the
    signal, accepts the four digit code, does a DNS
    lookup, and connects to the other node in Lansing
    Michigan
  • VOIP then goes back and forth in the radio
    network.
