Welcome, friends. March 2005 marks my third year making these little radios. I wrote the web pages to show off the projects that I made. I made the projects so I could write the web pages. I think I am in a big circle.

The projects on my website range from the pretty simple to some high performance crystal and one tube radios. There is something for everybody here. The projects shown here are ones that I built since March 2002.

I hope you enjoy looking at my projects as much as I have making them. There will be more coming. 73, Dave N2DS
