PowerSWR Annotated

I attached some temporary jumpers now for testing, they will be replaced later when I have my SMA connectors to make cables.

Note on the drawing below, P1 and P2 are both single windings meaning only one pass thru of a wire larger than 30 gauge.  S1 and S2 are 13 windings of 30 gauge wire.  Also be careful with the pins for the header as pin 1 and pin 3 are reversed on the motherboard versus the Power SWR board.  When in doubt, look for ground with a meter, and work from there when figuring out pin numbers.
