[Towertalk] ameritron rcs-8v

the back of the control box has 1,2,3,4,5 AND GROUND (note just because 
it is a nit and not a screw doesn't mean it won't be a placwe to attach 
a wire!)  Also note that when no power is applied the RCS8V is useless 
as far as antenna selection - unlike some competitors coax switches 
which when they are un-enrgized default to position one, etc.  You need 
12VDC to get a selection.
