Getting rid of brake solenoid noise is easy, just tuse a rotator without a
brake. Hy-Gain uses a spur gear that has little resistance to turning so
they put a wedge/brake on it. A brake can stick plus it has special
controller requirements as well as extra conductors. I have not owned a
rotator with a brake in decades.

I've often puzzled over my urban neighbour's lack of complaints about my
Ham-IV, clanking away day and night as I contest, DX, whatever, over the
last 20 years or so. Loud enough to wake the dead, I've often thought.
Why aren't they mad at me?
Is there any way to quiet that beast?
I've thought of perhaps some gradual application/release of power to the
brake, to ease it into/out of position?
A different brake material might not stand up to the rigours of constant
use.
I know there are tricks to ramp up/down the start/end of the rotation
cycle, but I don't think that they affect the application/release of the
brake.
I've just moved, and don't want to annoy a whole new set of neighbours.
Any ideas?
