A YouTube including "an update on Heil Sound's current operations, an interview with Heil Sound's Service Manager covering some frequently asked questions, and a visit with Bob Heil for a tour of his ham shack and a discussion of some fundamental ham radio concepts.". The video includes some very useful information on audio characteristics and how they impact your QSO.

Building upon the lessons in videos #274 and #275, this video describes how to design a 2-element L-Network to create an impedance match to the desired system impedance using series and shunt (parallel) inductors and capacitors. The design process is described, and then actual matching results are measured using a Smith Chart on a VNA. PDF of the show notes:

 This introductory video describes how complex impedance and admittance are represented on the Smith Chart, and how to convert between them. A VNA is used to illustrate the complex impedance representation on a live smith chart with variable resistive and reactive components.

Recording of a presentation I [W2AEW] gave at a VHF Amateur Radio Conference in October 2018. It covers the basics of the Smith Chart - what it is, how you plot complex impedance, obtain VSWR, return loss, reflection coefficient, transmission line effects and compute impedance matching networks. This presentation covers topics presented in some of my other videos, but does not include the live demonstrations shown in these videos:
