[TowerTalk] Yaesu G800 rotators

[Doug Rehman]

The Yaesu rotators use worm gear reduction to turn. By design, worm gears
can't ordinarily be driven in reverse by the load. So the bottom line is
that no additional brake is needed.

As to gentle stop, the 2800DXA controller has both a gradual start and a
gradual stop (as described in the manual); the smaller rotator controllers
do not have the feature.

Yaesu did offer an "Absorber Joint" (one model for the 800/1000 and one
model for the 2800) that goes between the tower and the bottom of the
rotator.
