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 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.
>>> 73 fer nw es gud DX,

Show quoted textYour Model SW9 is probably very similar to my Model 50.  Dick, 
followed a fairly predictable wiring system.  About the only differences 
were in the number of contacts on the switch.  You are welcome to 
download a copy of the Model 50 manual from the BAMA server.  Just look for Antenna Mart.  On the mirror site at look under antmart.
The Antenna mart switches were very high quality and not inexpensive.  
If you have the control box and the switch box and the wafers are in 
good shape, you've got a good piece of equipment.

The relay coils use what voltage in that unit?
I might have enough 'stuff' to help you build a control, as I build my  
own controls AND remote units.
