Looking for a Ray Jefferson L-100 loran set manual. I've searched Google,
Vivisimo, and DogPile. Found Kenneke, Sarrio, Sam's, and W7AFG. No luck at
those.

Assuming I may not be able to find one:

I'm guessing the L-100 is similar in keypad function, etc, to the PL-99
(nice little hand-held loran Ray Jeff made). I can get a manual for the
PL-99. Wonder if it would be close enough to make it worth it?
