  2. 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)
