Be a shame to lose AM band radio though, would mean the end of super simple
recivers like "crystal sets".
Every second kid still builds one of them - right ???
You bring up an interesting point. What will the schools of tomorrow bring?
Ok boys and girls, today, we're going to build a digital radio receiver:
First we have to learn about radio theory,
Then digital.
Then RF design in the commercial radio band
Digital design in logic, microprocessor, and DSP.
Embedded software design, and audio stream decompression techniques.
On the hardware side, first we learn about basic soldering.
Then PCB manufacture,
Then surface mount soldering.
Easy, that bit should only take about a decade or so.
The hard bit is the encryption, because we would be violating any number of
licences to teach you about the very last critical bit that would make your
radio useful at all.
Since that technique is not viable, we'll do it the easy way.
We'll get you to go to the Aldi's around the corner and buy a $25 receiver
from them.
If you manage installing the batteries and getting it to work, we'll
consider it a pass.
