So just finishing up the 3.1 build and I have bad stepper noise (and no signal)
Build is:
Rotator 3.1 build with stepper motors, satnogs v2 controller, PI3, RTL SDR V3, FM Notch Filter, 30DB LNA
I had to set my RF DB to 0. If I change to 1, it makes the waterfall red (since I’m running a 30db lna)
Satnogs controller is located inside the rotator housing, I twisted my stepper motor cables and cut them to length, then wrapped shielding around the stepper cables, and connected the end closest to the motor to ground lug on the satnogs controller board.
Control cable from satnogs controller is shielded (connected to the satnogs ground lug) then goes into my secondary box which houses the raspberry pi 3, rtl sdr, lna which grounds out on the box.
Also lined my rotator housing with aluminum tape.
Anything else I can do to eliminate the stepper motor the noise?
