Hi Marvin: I don't have a web site, but a 15 to 25 microhenry variable inductor and a 500 mmfd (sorry, my age is showing, Picofarad) variable capacitor will provide the basic components for what you are looking for.
These components will allow you to tune from 80 to 10 by themselves, but you will most likely have to switch in another 500 pf transmitting cap, or more, across the variable for 160.
My suggestion is to browse Ten-Tec's web site (www.tentec.com
) for the coil and cap, and the various handbooks for a schematic. Or you could buy a manual for the TenTec 238 along with the parts and go from there.
