Programs: Tom K8DMM: Why 50 Ohms? Why 50 ohms is standard in communications, to be presented at the May 11, 2023 meeting

  Our March 9th 2023 meeting had a
  presentation from John Portune - W6NBC  

Ferrite Toroid Baluns
Few hams have a clue of how to select a torroid and wind it to make a 1:1, 4:1 or 9:1 balun or unun.
The well-know radio books all seem confusing. This presentation shows the three very easy steps to
successful ferrite toroid design with very little math and a free on-line calculator.

There will be a question-and-answer period after the presentation.
