February 21st, 2023 — Last week we spent a lot of time looking at capacitive reactance. We then reviewed the first 4 critical metric measures of the Smith Chart: 1. The equator; 2. northern hemisphere; and 3. the southern hemisphere; and lastly 4. Home Plate. All that we left was phase. This week we will briefly look at those same things (but much more briefly) and then we will advance to setting up the nanoVNA.
