Digital Modes: Audio Files
Download these files to your laptop to play for students to introduce them to the many digital modes radio amateurs employ (all files presented below are in wav format except as noted).
If you have Internet access in your classroom you'll find a large collection of digital mode samples on this site: http://www.kb9ukd.com/digital/.
Resonance of Series and Parallel Circuits
Instructional tools developed by Steve Auyer, N2TKX to model how the values of the circuit components affect not only the resonant frequency but also the shape of the impedance-vs.-frequency curves and the Q of the circuit.
Also included, a resource to demonstrate far field patterns produced by two point sources affected by the separation, amplitude and phasing of the point sources. This resource allows students to
investigate how the three variables affected the patterns by inputting values for separation, amplitude
and phase to immediately see the effect on the patterns. It also illustrates the difference between linear and logarithmic pattern plots.
Here are some demonstrations illustrating concepts in radio science that have proven helpful in license instruction.
How Radio Signals Travel
This is a simple but very effective Demonstration of Lenz’s Law that you can bring into the classroom to show the most basic principle of radio science, how radio waves travel and the role of electromagnetic fields.
Here are some effective online video demonstrations of the same principle:
Using the Wave Modulation Board was developed by Mark Spencer WA8SME for ARRL's Education & Technology Program in combination with the Parallax USB Oscilloscope® you can provide a powerful demonstration of signal modulation for your students. The instructional board and can be purchased from the ARRL Store. The Parallax USB Oscilloscope® is no longer available and has been replaced by the Propscope®, which can be purchased directly from Parallax. Build the board yourself with instructions provided on the ETP Resource page.
Building Blocks of Radio
Using the 5 Building Blocks of Radio Board ( also developed for the ARRL ETP) in combination with the Parallax USB Oscilloscope you can provide a powerful demonstration of basic electronics components including the oscillator, rectifier, amplifier, mixer and filter, and how they work together in a radio.

Teaching Tips, Strategies and FAQs
from Jamie King, KJ4KJ
Pamlico Amateur Radio Society, Oriental, NC
You asked for some hints to use in classes. Here's one that we "stole" from the world of "hard" science (e.g. chemistry and physics and engineering).
We have had lots of problem over the past several years with the mathematical segment of the tech classes. Students are unprepared to even start to figure how many millithings there are in a megathing. We have developed a solution which seems to work in most cases, and we'll share it with you.
It is called "dimensional analysis" in the serious math books. You simply start with the given problem, for instance "which frequency is in the 2-meter band? (a) 52.0 MHz (b) 14643.0 KHz (c) 2.4 GHz (d) 28.430 Hz"
The students have memorized, of course, that the 2-meter band includes frequencies in the 144-147 MHz range. However, none of these appear in the answers. They panic.
OK, start with what you know. Take answer (a) first. It is in MHz, so that's OK, but it isn't in the range 144-147, so it's out. Take answer (b). 14643.0KHz. Let's make that into MHz so it can be compared with our knowledge base.
Expressed mathematically, the equation is 14643.0 KHz x 1 MHz/1000KHz. Always multiply. Arrange the terms so that the desired one is on top. Cancel the KHz units just as if they were numbers (that's the magical clue). Read the result. Works every time!
That's dimensional analysis, and it works for any conversion you can imagine; currency, electrical units, frequencies, even chemical measures such as "mols" that give high school student the willies. Our PARS (Pamlico ARS) instructors have used it for several years with great success.
BTW, our last three years of classes have had a 100% pass rate.
