Welcome to my homemade radio site. Below are links to the sets that I have built starting in 2002. I have enjoyed building them and I would like to show them off to you. This website has over 4.5mb of pictures and text, so stay a while. I have set up a visitors sets page. It is kind of empty now, but check it out.
