[TowerTalk] Remote Antenna Switch

[AD5VJ Bob]

Does anyone have anything on this Remote Switch?

For my new tower a guy gave me a control box for and old remote controlled antenna relay that he once used, but was in his junk box
and so he asked me if I wanted it.

On the back it has a paper stick on tag that says:

Antenna Mart
Box 7 Rippey IA  50235
Model SW9   SERIAL = _________

I searched Antenna Mart using Google and came to a website named 
MAX-GAIN SYSTEMS, INC
http://www.mgs4u.com/index.html

So I sent them an email asking them about this remote switch box
They sent me an email back telling me:

>>>
That one is very old, and was made by W0MLY in Iowa, before the company was sold in about 1990 to Bill Wall, KC4UZ, near Atlanta.

The old switch used a Lucas Ledex stepper motor, and sent pulses to index it.  Position indication was sent back to the control box
by a "coding wafer" which was indexed by the stepper.

Bill Wall completely redesigned it all, and used a totally different system, with gear-reduction motor drive, no steppers.

We have no data at all on the older W0MLY switch.
