« Last post by Mary B on Today at 06:49:16 PM »Here is why I needed to overhaul the Azimuth drive to begin with.
Need to revers engineer the circuit, easy enough to repair as just the rectifier module that blew but over all circuit is functional still.

maybe a PWM motor driver instead of an on/off design? Can ramp speed up and have less stress on everything. How my antenna rotors work, they ramp up speed for 2 seconds then ramp down to stop. With 150ish pounds swinging in a circle that is a lot of force on the central mounts/motors...
This is what I rotate... 2 of the 4 antennas mounted, still needed to add the coax lines(4 of them), power divider, preamp... it adds up fast for weight
The finished antenna array tracking the moon(and I can track the sun to measure sun noise to measure receive performance)
