Another great place to start broadcasting scanner feeds of your own is at
http://www.scannerbuff.net/
Click on streaming audio and follow the instructions. But
BEFORE you do this, you will need a
6' 1/8" Stereo to 1/8" Stereo Cord from Radio Shack. Its only $4.99+tax, so it doesn't burn a hole in your wallet. Go to the Radio Shack website & type in Catalog# 42-2387.
Good luck!
