Alan:

The phone number for LDG is:

(410)  586-2177.

The main contact person there is Duane Kincade.

I talked with Duane several years ago about providing the schematics and 
other documentation for the TW1 design, and at that time, he did not seem 
opposed, so long as the person requesting the material had a genuine 
interest in following through with the building of comparable units.

Even though the TW1 does leave a bit to be desired regarding SWR accuracy, 
it is certainly better than nothing, and can give the user at least a 
general indication of how things look.
