At Blue Ridge Amateur Radio, we supply everything you will need to build your OWN tuner, if that's something that you may be interested in. Some of these items are impossible to find, unless you want to go digging through the junk at a hamfest. Don't get me wrong, I love to dig through the junk at hamfests as much as the next guy, but when I find something I want it's usually attached to some other bulky item that the owner appears to be particularly fond of, i.e, it belonged to his great great grandfather, was used to communicate with the first Apollo moon flights, etc, etc... and he couldn't possibly part with it for less than $250.00....... You get the picture.
