Alan Wolke W2AEW from Tektronix joins us to talk Oscilloscopes. Alan is a field application engineer for Tektronix, the world's most well-known oscilloscope maker. He also has a YouTube channel that is chock full of great information for those wanting to better understanding oscilloscopes and test equipment in general. Alan joins us for a two part session to deep drive on oscilloscope features and applications. In part one, we introduce the oscilloscope, what it's used for, some introductory concepts, and some comparisons of analog and digital scopes. We also discuss probe quality.

George and Jeremy take a look at power supplies for powering radios and working on electronic projects. They explain the differences between traditional radio power supplies and “lab” Constant Current / Constant Voltage power supplies. They also provide helpful tips on what to look for when selecting power supplies for your radio or your workbench.
