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!
