[TowerTalk] Yaesu rotor

Don't forget that many T2X rotors (including mine) "stick" in cold weather
(it's been discussed at length on this reflector.) It's not a fatal problem
(they "unstick" after a few rocks back and forth), but very annoying. Also,
Yeasu puts the starting cap in the rotor, which increases starting torque.
If you have the Hy-Gain DCU-1 controller, you can remove the cap and install
it closer to the rotor, but not inside it (i.e., you have to weatherproof
it.) Not sure about the cap in the analog controller. Yeasu uses DC to move
the motor (Hy-Gain uses AC), and the speed is variable. The Yeasu does not
have brake wedge, which makes it a heck of a lot quieter than the T2X, the
solenoid of which makes two big "clacks" every time you turn the antennas. I
think the absence of a brake wedge has other advantages (and maybe a
disadvatage -- slipping?) but I don't know. One last thing: I saw one post
on this reflector claiming that the internal construction of the Yeasu is
very disappointing (it doesn't use the same high-tech system touted for its
big brother, the G-2800.)
