[TowerTalk] Remote Tuning of Shunt-Fed Tower

[Pat Chiles]

Dan,

The best answer I can give you is I am looking for something "precise" if it 
is cost effective.  I am currently turning a gamma vacuum variable with a 
cheap 8 RPM gearhead 12V DC motor from AllElectronics.  I used momentary 
switches, leds, and some "junk-box gears" to give me the capacitor's "end of 
rotation" warning.  I want to go with an omega match if the prototype will 
give me effective dual band operation.  The steppers are more compact, more 
precise, and more eloquent.  That being said they are not worth $220 to me.
