I am thinking of weather proofing the electrics. And with regard to the motor that drives it, should the 1uF capacitor be across its terminals, or across the output terminals of the shack situated control circuitry? Or both? I am using the Stefan DK7FC circuit. http://www.chriswilson.tv/phase-driver.jpg Thanks. -- Best regards, Chris 2E0ILY mailto:chris@chriswilson.tv
