Month Presenter Topic
February Jeremy Haley, WG9T

“RF IMPEDANCE AND THE SMITH CHART”

  • Resistance & Reactance (capacitance/inductance) >>> Impedance /Reflection coefficient and SWR
  • Relation between impedance and reflection coefficient / Impedance mapped onto a polar graph
  • Constant resistance circles, constant reactance arcs (circles) / SWR circles, rotation along a 50-ohm transmission line
  • Open-source, cross-platform RF/Microwave software for learning/experimenting: QUCS http://qucs.sourceforge.net
  • Example impedance calculations at either end of the feedline / Impedances of an approximate 40 m dipole at 20 m and 17 m
  • Simple matching circuit calculation for the non-resonant 40 m dipole that could allow 17 m operation.
January Paul Berge, K0DJV

Amateur Radio at Microwave Frequencies: Hands-on equipment and concepts demonstration of getting on the air at UHF and above. “You will be surpised at how little it takes to get into microwaves. You can build a rig for less than $200.”

Example components:

  • discarded satellite TV dish / mixer (~$50) / stable frequency source module (~$50?)
  • power supply for freq. source module (requires -20V @ 1.5 amp) / Your existing VHF/UHF SSB transceiver for use as an IF section, or even a 10m rig could be used.

Concepts discussed and demonstrated:

  • rectangular waveguides vs. coaxial cables or twin-lead t-lines
  • polarization
  • near-field and far-field regions in the vicinity of an antenna or aperture
  • power units Watts, milliwatts, dBm, dB, orders of magnitude, signal levels
  • standing waves
  • reflective materials, lossy dielectric materials
  • cut-off freq. in waveguides
  • microwaves behaving like light rays
  • parabolic dish antennas with very high gain and small beam-width
  • interesting propagation effects/unexpected communication paths
