This is what Iam thinking but I wonder if there a bad batch from channel master that the seals are defective.

When it gets above freezing it works so that proves there is moisture that might be causing the problems ?

If you can move yours when the temp is below freezing there must be a reason why some of us is having problems.

If the tech guy from Channel Master that I have been emailing does not respond tome by tomm I will call him.

My CM 9510A rotor sometimes does the same at night. Contrroller turning but, antenna is not. My system has been on my roof for about 8 -9 yrs. Daytime it always works.
Looked at seal yesterday no cracks and seemed still flexible. ? Sure seems like cold nights affect it .

My Zenith ZENRTR1 rotor sometimes doesn't work either. It's only a month old.

What the H-E-double hockey sticks is going on with these things?!

I bet there is a problem with the batch of current rotors.

When I called Channel Master and enquired about it the person said no we dont have a problem we have sold thousand and have not heard anything back.

Yea what companies would admit that they have defective products.

Here's another contestant on the "Is the Channel Master 9521 rotator a dud".

I installed my first rotator in early/mid december. Temps were above zero and we had some rain. It worked great until the temps went back under zero. It seemed to work fine during the day and would seem to get stiff at night, moving at less than half it's normal speed, and would go out of sync because of this. Thinking it was my cable, I braved the cold and replaced my cable with a 5 strand 18 gauge cable. Of course, it was nice and sunny that day and it worked a treat. The next morning I tried it before going to work and it was back to its useless self again. I took it back under warranty, much to the surprise of the dealer ("we never have returns on these").

Luckily, we had a warm January and I got a window of time where I was able to climb onto my roof without killing myself. It worked perfectly and continued to do so until it rained last week. So now once again, I've got a useless rotator on my roof. My guess is that moisture gets in them and freezes.

So, bottom line is that these rotators are only good if you live in a warm climate. Maybe we'll all have to install small heaters in them to keep them warm and dry

I am so thoroughly unimpressed by Channel Master right now that I'm going to stop here before I say something about them that will get me banned from this forum.

If you're running heavier TV gear (such as for Deepest Fringe) up on a mast with high wind load you might want to consider a Ham-radio level rotor like a Yaesu or Hy-Gain. They're available in shops across Canada like Burnaby Radio in BC, but if you need a web source you could try this one:

This thread is for discussion about Archer, Channel Master, Yaesu, Hy-Gain, Zenith, and other rotors and related information.

Does this look like a good price for an Archer rotor? Regular $139.99 on sale for $89.99 on The Source's web page:

http://www.thesourcecc.com/estore/Pr...roduct=1501245

3-conductor cable sold separately. Anyone have experience with this model? Does it have an old style dial controller or a newer remote control one?

Looks like a channel master to me I bet they might even come from the same factory.

The Source has extended that Archer 150-1245 $89.99 rotor sale to June 18, 2006:

http://www.thesourcecc.com/estore/Pr...roduct=1501245

Yes they are Channel Master!

Thats a good deal the Source has going... but what kind of control box does it come with? I bet it's the old style with the knob.

I did a little bit of research and found this out. The Source is using the same catalog numbering system that Radio Shack used however they've just replaced the dash in the catalog numbers with a zero.

Rotator catalog number...
The Source= 1501245
Radio Shack= 15-1245

The 15-1245 Rotator is indeed the one with the Knob

The US Radio Shack does sell the digital control box with remote for another $54.99US so maybe the Source will do the same?

Do you have the RS catalogue number for the digital box?

Shouldn't an ATSC tuner be able to remember position and control antenna? Don't have one yet, all new to me.
