Re: Portable AZ/EL Rotator?



Hi,

The "roll your own" az/el controller electronics PCB as seen on my web
site has been withdrawn and will be replaced with a controller PCB
with the following specification.

UNI_TRAC and KCT compatibility

75 to 1000 Ohm range for the geared  feedback potentiometers

AZ and EL channels

opto coupled triac switching for low voltage AC split phase motors.
OR
opto coupled power FET switching for low voltage DC motors. (Polarity
reversal switching arrangement)

The PCB accepts either of the above configurations.

Regards

Dave Lamont
