Your question has already been answered more than effectively by others. However, if you are still keen to modify an ordinary portable radio then I have got a magazine article laying around that will help you to do it.
You would probably be better off getting hold of a cheapish scanner as this would do a better job, but if you want a copy of the article then drop me an e-mail. It is a scanned copy, so will be easy to send.
