# A New Year, A New General Class

The 2006 version of my General Class license course started this week. It’s a much smaller class this year. Instead of the 28 that signed up last year, I have only four in the class. It’s too bad that I don’t have more, but with the smaller class I can help each student individually.

It also lets me hold the class in my basement, rather than a classroom somewhere. This makes it a lot easier. I don’t have to schlepp equipment to the classroom, and I can think up ways to demonstrate points on the fly.

For example, two years ago when I was teaching a class of five in my basement, I was explaining the concept of impedance. I drew the diagram of how resistance and reactance combine vectorially and did a sample calculation. Then, it hit me that I could use my antenna analyzer to measure the reactance of a coil, the resistance of a resistor, and then the impedance of the resistor/coil circuit.

First, I made the resistance and reactance measurements and calculated the reactance. Then, I actually measured the reactance. Voila! It turned out very close to the calculated value. I couldn’t have done that in a classroom because I wouldn’t have had the components, and at any rate, the students way in the back probably couldn’t see the demo, anyway.

I say that there are four guys in the class, but one of them has already passed the written test. In fact, he’s already passed the Extra Class written test. Why is he taking the class then? Well, he passed the test by memorizing the answers. So, he thought he’d take the class in order to really learn the material. Wow, does that put the pressure on me or what?
