Homebrew Radio Links - K3UH (Russ)

I've tried to list links where there is (1) a picture, and (2) a schematic. Some of the pages are in other languages, particularly German. Where I don't want to slog through in a half-understood language, I use Google's translation page. Try it; it opens new worlds. (Version 1.0.3, September 8, 2007)
