It's actually really easy once you understand it. The polarity and frequency are just spinning the antenna in a circle, and + and - are going clock and counter clockwise, you're just trying to align both with the signal.

Just an idea, could be helpful if their was a more automatic tutorial maybe with the Signal Machine? Showing how it is done first on each panel by itself, finding the signal, locking in the polarity, playback & enhancing, then letting you try it for yourself. Just thinking of ways it could be improved. -arcade_portal32
