Thanks Stampeder... I've got the actual tower and the rotor plate does not have a pipe section to attach the rotor to. What the picture is showing is a bracket used to mount and secure the lower u-bolt for the tower-mast.
I've asked the dealer as well, and he's never seen it for the GN tower.
I may just have to fabricate this from scratch!

Ya, I'm probably thinking of other brands of rotor plates. Those Delhi illustrations fooled me! :D

In the end, I phoned up Delhi about the rotor plate mounting. They said... read the instructions. I said.. what instructions? (none had come with the tower) All I have to do is reverse the bracket and it should bolt up to the rotor and center the mast correctly. It's still seems a bit flimsy but I'll give it a try.
Our old "Crown" dial controller has finally died and I bought a new Channel Master 9537 remote controller. The old controller was wired this way:
How should it be wired to the CM9537? All help would be appreciated.

JMC, is your original rotor controller cable a 3-wire or a 4-wire?
If you're using a 3-wire system just attach your white wire to terminal number 3, and then you need to test with the black and red wires on terminal 1 and 2 for directionality of rotation to match what your antenna did before.
If you're using a 4-wire system just twist wires 3 and 4 together and put them on terminal 3 of the new controller.
Couldn't get the 9537 controller to work, so I worked on the old crown controller and got it working and was able to jog the antenna drive back and forth. At least I know it isn't the drive. Could the old drive(might be 20 to 25 years old) not be compatible with the 9537? TIA
JMC p.s. it is a 3-wire cable

I think you'd better phone the Channel Master support line about controlling that old rotor. Is it mounted up pretty high, in case you need to swap it with a new unit?

My old rotator model 9512 died......picked up the model 9521 which i was told was compatible with the 9512....hooked it up but the antenna doesn't operate with it. There is nothing wrong with my rotator on the antenna...is there something i'm missing...Does the model 9521 have be set up differently ??? Any help would be great

As long as you wired the control unit properly it should work.
Are you sure the rotor outside is working or there is no broken wires going to the rotor from the control unit?
2007-10-14, 05:24 PM
The 9512 was the nice old control with the big dial right? ... I really liked those!
The 9521 is the rotor motor and remote control kit
Did you replace the Motor too or just the control?

Thats the old baby that died on me.....no broken wires....the old rotator still moved the antenna.....only thing is when i looked at the manual it had green wire where mine is white.....don't know if that makes any difference...just replaced the control

When I also look to the guide the wire configuration is different than what i had previously with the 9512 .........Do i set the 9537 with the wire configuration for the 9512???? (Red-1 White-2 Black-3 Wire Config for 9512 ) because nothing is happening with the recommended setup......

With these rotors there are always 3 wires. One is common and the other 2 each are to turn it one way or the other.
Looking at mine the #3 terminal is the common and this wire is black. #1 is red and #2 is white.
Sounds to me like you have the common wire mixed up with one of the other 2. Try to swap them around and see what you get. Don't worry you can't really do anything that will hurt it.

Thanks that fixed the problem.......

Thanks that fixed the problem.......
You're very welcome Zoolou! glad you got it working.

Hey Videobruce. It's been 6-7 months since you got the Eagle Aspen rotor. Would you still recommend it? And did they ever fix the lagging display update? Inquiring minds want to know!

Pickering flea market: $65 channel master rotor. The one that can receive the signal from a remote and change positions. (you change the channel, and it automatically changes direction)

I have an 18 year old rotor that's still humming but I'm not sure whether it's time to retire the unit.
Lately, I find that I have to re-sync the unit quite often. Channel locations seem to drift more towards the west. After I re-sync they're more Southerly. Even then I find the channel locations all over the place from where I expect them to be. Is it possible for the drive to be slipping? Is it possible for the rotor dial to be slipping?
I've recently upgraded from analogue to digital so is this part of the behaviour of digital transmission?.
Any thoughts out there?

Most rotors have a brake and/or clutch that can wear out over many years and make aiming sloppy. After 18 years I would say that its age is the reason yours is constantly getting out of sync or it is turning too much or too little each time. You will definitely be happy with the precision of a new rotor. :)
