  • Getting Started with Electronic Projects
    The project in this chapter was probably more challenging than the previous ones, so I hope you were successful and made some new friends in the local ham - radio community. We learned about crystal filters and how they work.

  • Ham Radio Gets Upgraded with Modern Technology
    Unlike ham radios from the analog days of vacuum tubes and crystal oscillators, today’s radios have few electronic parts outside of the antenna. The computer can correct errors and filter out interference, greatly expanding the range of a small antenna.
