[GreenKeys] Polar Relay

[Tom Hunter]

Eugene,

The 30 mil bias must always oppose the 60 mil neutral loop.

In spacing (no current in the neutral loop) the 30 mil bias pulls the polar
relay to spacing.

In marking (60 mils in the neutral loop) half of that 60 mils counters the
30 in the bias winding, which leaves 30 mils to pull the polar relay to
marking.

So the effective 30 mils each way should create no distortion going through
the polar relay. I also believe a properly adjusted polar relay is bistable
(which would not matter in this situation.)
