Before everything goes digital, I'm going to show you how to make your OWN functional Speaker capable SW Radio in less than 5 minutes! Just watch, and I'll show you HOW to make your very OWN radio!.
All you need is the following (you can get it on eBay for less than 2 dollars if you shop around): 1x 100 ohm Speaker, 200k Resistor, LM741 Op-Amp (or compatible), 220uF Electrolytic Capacitor, 10 nF capacitor, 15 pF Capacitor and a 47 pF capacitor, a Small cheap BreadBoard + some standard 1-core wire for Breadboard (find this at RadioShack or somewhere else). And a 9 volt battery. The components aren't critical, meaning you can easily use 270K or 180K instead of 200k resistor, or 100uF to 400uF electrolytic capacitor etc. Just find what you have, and connect it as I did...and it'll work for you!
