[TowerTalk] Motor drives for vacuum caps

[Dennis Ashworth]

Has anyone discovered a reliable scheme for remote adjustment of vacuum 
variables? I have two antennas with vacuum variables at the base and would 
very much like to tweak them from the shack. I'd need the ability to 
reverse direction and ensure I didn't go beyond the acceptable travel of 
the capacitor (maybe some limit switch or turn counter arrangement?). I'd 
prefer to stay away from LED/encoder wheels, etc in my high RF environment, 
but that may ultimately prove the best solution.

Ideas welcome!

Thanks,
