Making a transceiver from scratch is a pretty awesome project. It can take a while, though.

There’s a lot of theory of operation that factors in physics and engineering.

I’m a radio technician, so I’m biased, but if I were a science teacher I would be amazed if someone could build a good working radio from scratch.

The basic operation of a radio is pretty simple… actually making it work without noise is pretty hard.
