Re-using Molex PC connectors
|The Molex terminals fit as plugs and sockets in this connector.|
The Kenpro rotator that belongs to the Versatower has a strange type connector ... 10 pole idiot proof.
This old rotor has 6 wires. 3 for the indicator and 3 for the motor.
The voltage of the potentiometer in the rotator is simply displayed as 0-360 degrees by the voltmeter in the indicator.
My own newer type KR-400RC uses 5 wires 2 for the potentiometer and also 3 for the motor.
The indicator has a 360dgs 500ohm potentiometer same as in the rotator. Both are part of a Wheatstone bridge. The indicator motor drives the scale to balance.
I had to find a way to extend the rotor cable with 30m extra without modifying the connector.
The only plug that fits to this pins where the Molex power plugs used in PC's. I had some in the junkbox.
This Molex type connectors are ingenious simple and high reliable.
They where developed by Molex in 1950.
Now both controls are near the radio.
The Steppir cable was already about 30m long is extended to 60m using a cable with 25pole D-connectors. The cable is 0.25mm² 15 wires
It seems to work okay without extra Voltage boost.
The moral of this story do not clean out your junkbox too soon.
Today morning 28MHz was good many decodes of VK2KRR (100W) and VK5AKK (10W) and heard with 5W by both.
Also FR1GZ many decodes T61AA & A45SWL
But later ST0R was very weak and working south EU only.
