Science Buddies: "Ask an Expert"

Hey,
Can anyone help me with this question:
How do Radios work?
Please respond if you see this.
I need a specific answer.
Thanks to all who are going to answer
Thanx

This is one of those situations where Google is better suited that this newsgroup to answer your question. Type "How do radios work." into Google and numerous websites pop up with good explanations, ranging from simple to complex.

Hi Dodger,

There are several types of radios. For example AM, FM, and the new digital format and satellite radios.
The earliest developed radio type was AM, and these sites explain it:

Here are two Science Buddies radio project write-ups about radios:

No one of these sites seems to give what I would call a complete answer to your question, but collectively they will get you started. If you want more, try these

Still not satisfied?

Try to find a copy of the

ARRL Handbook of Radio Communications

This is probably available from your local library or can be bought through bookstores or online. It is an excellent reference on all things about radio and has projects to build as well as theory.

This is a very interesting field to study. Have fun investigating it!
