  • In 2016 a disaster response network of trained radio users sporting an ideal budget of $0 per person was born. While amateur radio existed through most of the 20th Century, by the 21st century it had become a bourgeois hobby for older white men. The established purpose of amateur radio in the regulations of the FCC had always been to set up a voluntary interest in radios for use in emergency (both environmental and military), but with the rise of commercial Internet radio networks (Wi-Fi) and cheap long-haul telecommunications networks, ham radio shacks became a collection of exclusive and fetishized gadgets. Younger people drifted towards the Internet.

    But in 2016, emergency came calling. A group of three coastal superstorms flooded most of the West Coast, and left the population without infrastructure for weeks. A small, previously unknown group calling themselves “Solarpunks” sprang up, to fill the communication gap. Using a number of levels of financial commitment—$0, $10, and $40—they began training a culture of youth hungry for the basic skills of radio and electronics, and then letting them train others. They descended upon the rubble to pull out bits of aluminum for antennas, drying out coaxial cable, and rescuing batteries and stereo speakers from stranded vehicles. Using the disabled tech of a failed infrastructure, they began connecting themselves into a network of learning and doing. The old-guard hams had all fled to high grounds weeks ago, but the Solarpunks remained, continued their modifications and grew in numbers.

    We will detail the speculative future-history of the Solarpunk Ham Radio Club and its method of spreading the use of radio with no financial investment. It took amateur radio back from a toxic commodity culture, just when it was needed most. The Solarpunks couldn’t duplicate the permanent infrastructure that needs billions of dollars in funding. But with a foothold based on a resilient jugaad rather than expensive gadgets, they were able to find a way of teaching each other, that made their network resilient in a way that money could not.

  • Then, there’s backup. Take the European HAMNET, for example. That’s a four-thousand-node high speed data network covering a large part of continental Europe and providing full IP connectivity at megabit speeds. It connects to the Internet—-ham radio owns 16 million IPV4 addresses, believe it or not—-but is independent of it, doing its own robust and flexible routing. If the Internet was to go away, HAMNET would still be running. The same’s true of nearly all ham radio infrastructure. When everything else fails (power, comms, roads), ham radio is still there. These days it can even be a full-fat digital medium.

  • Q: The first question is usually “Why use amateur radio when you can use the phone and/or Internet”?

    A: This question is almost impossible to answer. Why do some people ride a motorcycle if they can drive a car? Why read books if there is TV? And so on…

  • electronics, etc, following the map I have drawn out on paper. Major sections so far are

    • electromagnetism, fields, electromagnetic circuits, electromagnetic waves
    • conductors, insulators, dielectrics
    • voltage and resistance and power
  • The electromagnetic specrum

  • radios end-to-end, finally (intro)

  • The Time Domain

  • The Frequency Domain, audio frequencies

  • Modulation and things, more complicated radios

    • capacitors, inductors, impedance, transmission lines
  • radio waves in free space, propagation, antennas

  • amplifiers, transistors, semiconductors

  • Doug, mostly

  • Operating procedures

  • Regulatory stuff can and should be self-studied throughout the course

  • Getting started on HF

  • Crystal Receiver

  • Audio Amplifier

  • Transmitter

  • Beat-Frequency Oscillator

  • Reference Information

  • We need:

    • A few irons
    • Lots of flux
    • Lots of wire
    • clippers, strippers
    • Solder
    • Something to build
  • CW is no longer a requirement but in the event that one wants to learn it after qualifying the following is a good program. Go the following site and download Version 9, a “freebie”. One caveat - it only works on the WINDOWS platform.

    http://www.g4fon.net/

    FYI, another way to acquire the equivalent of Basic with Honours is to to qualify with CW at 5 wpm. Details at:
