Yeah, I was going to say crystal controlled.
That's actually the exact thing.
That is almost exactly what it looked like.
Make your own working radio without batteries.
Yeah, and it uses a, I was going to say crystal controlled radio because it uses a crystal diode on it.
And then the frequency modulation, like amplitude modulation isn't as efficient as frequency modulation when it comes to for the vocoder to produce sound.
Amplitude modulation travels farther, but it doesn't have the amount of information.
The carrier wave can't be modulated with as much information as you need.
Whereas frequency modulation is much quicker, megahertz, and you can amplitude and add more information, which is why it sounds better.
So FM sounds better, but it doesn't travel as far.
