amature radio

So I’ve been looking recently on buying a radio just to LISTEN on. (No transmitting just to listen to chatter) I’ve been in the market for radios and the Motorola PR400 has sparked my interest price wise on how cheap you can get them for on eBay and still have the Motorola brand. The question...

I am just getting into all this stuff and would like to get my HAM Radio License. How do I go about doing that? I live in Tullahoma Tennessee. I also would like to do SKYWARN if anyone could help out with that to? And one more thing, where can I get a HAM radio? Thank YOu all for the help.
