Good day,
i have a great problem, perhaps you can solve it.
This year i bought a house with a antenna mast and on the mast
is a rotator. It is the KENPRO KR-1000S with the serial:
MI9034 ... 2 weeks ago the controlling unit had a failure so
i opened it and saw that the rubberwire from the motor was broken...and i got a original one from the kenpro-suplierer
in germany and tried to change the broken one.
Due fingertrouble the control unit was to fall down and i caught it in the last moment BUT the "wheels" where faling down and the vari-resistor was no more the the original position.
But now here is my question... could you please be so kind
and help me to fix my KR-1000S ?
I need a plan to adjust the controlunit including the
vari-resistor, so that the right antenna direction will be shown to me. In the moment everything is mismatched in the control-unit.
My very best greetings and many thanks in advance for your
attantion, work and spent time..
Yours sincerly Michael Grehl, DH6JL

Hi Michael
I've been repairing the controller of an old Kenpro KR-600RC recently - I expect the schematic will be similar - please check my webpage http://www.qsl.net/gm3woj/rotators.htm
It is not easy to adjust the 5 potentiometers - there should be 3 presets on the PCB in the controller. The KR-600RC has a gear-driven pot in the controller but otherwise probably the same circuit as your KR-1000S
Please e-mail me off-reflector for more help...
