Sure thing. The ARRL which stands for American Radio Relay League. They are an association of amateur radio enthusiasts. They are involved heavily in the hobby. They put out a set of books which walk you through what you need to know. http://www.amazon.com/ARRL-Ham-Radio-License-Manual/dp/0872599639
There are also a bunch of videos on youtube. Www.ke0og.net/training Www.hamwhisperer.com

Nothing beats the books though if you want to learn the material. It seems you are a n00b in the ways of radio and the whole subject. I can tell you in 95% of the cases hams are great people that want to teach and learn. Feel free to send me questions you may have I'm no expert but there are plenty of people who are.
Ah, that's understandable.
Check out the ARRL, they're a great resource. If you decide to get into ham radio I'd suggest you get the study book. You can also look around for a local club that might have resources.
