Can any one please confirm or deny?

I found complete military manuals with alignment data at:

http://www.kg7bz.net/

The adjustable coupling is used for alignment. Two receivers have
variable coupling. The coupling is set for minimum (greatest
selectivity) for adjustment. Then either just the first or all three
are set for maximum coupling depending on the particular model.
I knew I had seen these manuals somewhere but had to look at the
bookmarks on another computer to find them.

Wow, thanks for bringing KG7BZ's web site to the front! The alignment
procedure you found there explains a lot.
