Key quotes
· 5 pulledRadio communications play a key role in modern electronics, but to a hobbyist, the underlying theory is hard to parse.
I'm hoping to provide an introduction to radio that's free of ham jargon and advanced math.
A Biblically-correct introduction to antennas, superheterodyne receivers, and signal modulation schemes.
We know about frequencies and can probably explain the difference between amplitude modulation and frequency modulation.
Most of us find it difficult to articulate what makes a good antenna, or how a receiver can tune in to a specific frequency and ignore everything else.
