[TowerTalk] HG-70

[wn0x at earthlink.net]

The original kit from HyGain included three double pole switches which were wired such that the top limit switch stopped the tower an inch or so before reaching the metal stop.

I have my bottom switch set so the tower stops a bit high to prevent the rotor from sitting on the second section.  

There is a third switch that disables all motion if the cable becomes slack.

The remote kit adds two relays and a switch box.
