Build something and then experiment with different antenna configurations

GOOGLE can be very helpful. Simply enter in some of the key words that you have used here in your post. Then press the 'enter' button. A list with thousands of possible websites with those words in them will appear.

The link above is from a google search I just ran. I typed in "FM radio circuits". The link I posted was the 4th or 5th item returned.

Give it a try...it's fun!
