I've been studying for my amateur radio license recently, and this article is a great introduction to the basics.

But really, if you want to get your hands dirty with some practical electronics, and also want to be able to communicate without relying much on nearby infrastructure, amateur radio is a great hobby.

To get an idea about radios, I made a crystal radio when I was in 7th grade, I only had few components. The only component I had difficulty in getting was the crystal oscillator (I was living in a rural town).

It was mind blowing when I first heard the audio through IEMs ! It felt magical that this contraption was working without any battery source.

The crystal radios I know don't have crystal oscillators - the word "crystal" refers to the diode.
