[TowerTalk] Figuring Out Prop Pitch Wiring

[Ward Silver]

Hi all,

As you may have heard, John N7TT is the proud new owner of the W7RM QTH in
southwestern WA.  John has a bit of a project on his hands, to say the
least, as he restores the "infrastructure".  In the process of preparing the
QTH for sale to what the family expected would be a "normal person" (to use
John's words), all of the cabling was yanked from the radio area and into
the yard, unlabeled, in preparation for a rapid takedown.

John now has nearly a dozen prop-pitch motor/selsyn cables laying on the
ground without any indication (so to speak) of what the connections are at
the tower.  It would be really great if someone could suggest a method -
such as an ohmmeter or DC measurement - that would allow him to figure out
the connections without having to laboriously climb up and down the towers a
million times.

I've volunteered to help figure this out for John, but maybe this would be
of help to others with "mystery wiring", too.  Such nfo might be of use for
troubleshooting.  Suggestions?
