The "T-Hunt Bible" (at least in English) is called
Transmitter Hunting: Radio Direction Finding Simplified by
Joe Moell K0OV and Tom Curlee WB6UZZ. (Copyright 1987 by TAB books.) You can find a link from Joe's web
site at
HomingIn.com along with a lot of other articles, references and extensive links.
It is somewhat dated, as it doesn't cover Offset Attenuators or GPS-assisted computerized plotting, etc.,
but covers a lot of the principles and many construction articles, and you'll also find a list of Joe's articles in
various magazines over the years that discuss them. (I know Joe has been considering writing a new book or
two, I haven't heard anything serious enough to suggest you wait for them.)
