Does anybody know in using the HB25, if it makes any difference where or not the signal (PWM) goes thru a twisted pair, or a just 2 wires, untwisted?· Does the PWM get distorted in a twisted pair?

    For wire runs of about 3 feet, you shouldn't notice any difference. Capacitive, crosstalk, and EMI effects come in to play for longer runs.
    For heaven's sake, use solid grounding techniques, as always - One return point for all grounds to avoid ground loops, etc.
