Shortwave 101: How AM and FM Works [13:21] (youtu.be)

Learning about shortwave radio is a step by step process. One key point is a topic called modulation. It means adding information to a carrier wave either by amplitude, frequency, or phase.

This video shows how AM and FM radios work and answers an interesting question:

Why does lightning interfere with AM but not FM signals?

If you know the answer, you're probably a ham radio junkie and don't need to watch this video. Otherwise, enjoy!

Couldn't watch the video... Right after it started and I heard that voice from the old 1950's public service announcements about nuclear war and I stopped-dropped and rolled under my desk.
