3 / green #22
4 / blue #22
5 / orange #22
6 / yellow #22
7 / brown #22

start cap is 108-155uF bipolar


On the rotor box, pin 1 is the only male pin on its connector.  Pin 5 is the only female pin on the other connector.
Pin 1 is ground, and needs to be the highest current wire if there is a difference.
Pin 2 should be high current if possible also.
This is also the pinout on the rotor-end of the rotor extension cable.

On the rotor, and on the control box end of the rotor extension cable, pin 1 is the only female pin on its connector.
Pin 5 is the only male pin on its connector.



field strength tests before antenna, rotor, coax work
tested with mark N8TWO, receiving on simplex in his van, parked "in his usual spot"
rx one bar stable at 7w
rx 5 bars stable at 18w (higher wattage does not appear to noticeaby improve signal)

test after hardline and antenna installed, full scale all the way down to 5w, definite improvement
swr is rather high (1.5 - 1.7) but the signal loss has dropped so dramatically it's a huge improvement
