1. [TowerTalk] rotator problems (score: 1): Author: gbay@home.com (Gerry Bay); Date: Mon, 20 Sep 1999 09:30:07 -0400; Hi all. I have a ham IV turning a TH-11DX which has been working fine for over a year. Prior to that, it turned a KT-34A for about 10 years. When I put up the TH-11DX last year, I performed normal ma; /archives//html/Towertalk/1999-09/msg00445.html (7,563 bytes)
2. [TowerTalk] rotator problems (score: 1): Author: K7LXC@aol.com (K7LXC@aol.com); Date: Mon, 20 Sep 1999 10:02:19 EDT; Loosen the bolts on the thrust bearing and try it again. Or loosen the mast clamp and try turning the antenna by hand. If the TB is binding, then just leave it loose and no harm done.

This will tell you if there is a binding problem. It will also tell you if mast/rotator are aligned as you will see the mast rubbing unevenly.

4. [TowerTalk] rotator problems (score: 1): Author: aa4nn@juno.com (Joe L Blackwell); Date: Mon, 20 Sep 1999 14:20:05 -0400; Same type of thing happened to my GS1000SDX. In my case what had happened is the thrust bearing somehow got cocked up in its cradle and that put the mast in a bind as the antenna rotated from 320 to; /archives//html/Towertalk/1999-09/msg00465.html (7,768 bytes)
5. [TowerTalk] Rotator problems (score: 1): Author: Dan Evans <dan.evans@insightbb.com>; Date: Mon, 20 Jun 2011 16:58:29 -0400; I have an odd Rotator problem. In my Rover setup, I have an old Hygain AR40 rotor. For the past several years I have been having an annoying problem. Whenever I turn the antenna the rotor moves to th; /archives//html/Towertalk/2011-06/msg00161.html (8,993 bytes)

Re: [TowerTalk] Rotator problems (score: 1): Author: "Clint Talmadge W5CPT" <w5cpt@bellsouth.net>; Date: Mon, 20 Jun 2011 16:12:23 -0500; You said " I don't believe the inverter is the problem." - I am going to bet it is. Many inverters are square wave output and will cause havoc with anything that is motor driven. The output is not re; /archives//html/Towertalk/2011-06/msg00162.html (10,235 bytes)
7. Re: [TowerTalk] Rotator problems (score: 1): Author: "Jim Hargrave" <w5ifp@gvtc.com>; Date: Mon, 20 Jun 2011 16:22:19 -0500; Dan, Sounds like a perhaps a waveform issue. This is especially critical on rotors that use a series capacitor on the motor. The Inverter may not be putting out a good sinewave. Perhaps it is more li; /archives//html/Towertalk/2011-06/msg00163.html (10,729 bytes)

The AR-40 uses a very simple voltage comparator to control the motor; the reference voltage to the comparator is not regulated in an; /archives//html/Towertalk/2011-06/msg00164.html (9,521 bytes)
