“Introduction to Impedance, SWR and Transmission Lines” at 2025 HamX

simple standing waveJoin Greg Algieri, WA1JXR, for an introduction to what complex Impedance is, how to measure it, and how Impedance is related to SWR. Greg will explain how these concepts apply to transmission lines, and how the waves and power travel from your transceiver to your antenna. 

WA1JXR began his Amateur Radio journey by asking his Dad for a Blue ‘Gillette Razor Blade’ to make his first diode receiver, which lead him to get his Amateur Radio license, higher electronics education, and an entire career with Raytheon, where he worked in radio and antenna design. Greg is active in the Amateur Radio community as a teacher for new and existing hams, restoring vintage radios, and getting on-the-air. He’s been a member of NEQRP since its beginnings, a teacher for Long Island CW Club, and is an ARRL WMA Assistant Section Manager and Technical Coordinator.

HamSCI imageBe sure to visit the HamSCI booth at the 2025 Northeast HamXposition and find out how the organization is helping to answer questions like: 

  • How does the ionosphere respond to inputs from space and from the neutral atmosphere?
  • How does the ionosphere couple with the neutral atmosphere and with space?
  • What are the sources of medium and large scale traveling ionospheric disturbances?
  • What are the causes of Sporadic E?

HamSCI, the Ham Radio Science Citizen Investigation, is a platform for the publicity and promotion of projects to advance scientific research and understanding through amateur radio activities.

Also, be sure to catch Dr. Nathaniel Frissell, W2NAF, our Saturday Grand Banquet speaker. Nathaniel will discuss the results from a number of recent HamSCI experiments, what’s next for HamSCI in the future, and how you can participate in these exciting projects!
