1M Channel Master not working.......?

[RT-Cat]

I picked up a 1M Channel Master on Labor Day from Pixl(Jim), installed it, and have been making many attempts to pick up anything. I have tried two different Geosat Pro LN-Geosl2 blt, one WS International esx522, and one XtremeII without much luck. With the XtremeII I was able to get 31Q on 125 from PBS. I now have seven 1/2 hour sessions working on this and am nowhere. When I don't pick up much I give up after about a half hour so I don't get ticked and start throwing things around.
Pixl has Emailed me pictures of the LNB he used on this dish. Compared to what I have tried, this one would be called BIG. Nothing I have ever seen before.
So to anyone that has one of these dishes, what LNB are you having luck with?
.
And yes, I have wiggled the dish back and forth, elevation up and down as much as 10 degrees, and skewed the LNB to almost in a circle. Nothing works.
I would post a picture of that nice dish, but for some unknown reason I can't post pics anymore. They just will not upload. Problem fixed. Thanks MS.

I've used those with Dishpro lnb's, original Primestar lnbs, a Satav PLL, and various others all successfully.

ONE of my 1 meter CM's is OFF 5 degrees on its elevation, and unless the arms are installed wrong, I suggest yours can't be off any more than that maximum. They do have a very tight beam. My guess would be that you have the lnb back too far in the holder, and aren't at the sweet-spot.

My best suggestion is to mount a DP lnb on it (take the outer shell off), and tune in a Dish Network high-power sat. Get that all peaked perfectly, and see what's off on the mount or whatever. Then switch back to a standard KU lnb.

Could it be...?

Is it on the stock mount?
Does the indicated elevation on the mount match what you expect for your area?
.
Is the LNBF centered on the dish?
Take measurements to be sure.
.
Look for manufacturers assembly drawings.
Maybe you reassembled it incorrectly.
.
If the dish isn't damaged or warped (string test?), I'd suspect you are not focused.
?..

Is it on the stock mount?-Yes.
Does the indicated elevation on the mount match what you expect for your area?-Yes. With + and - 10 degrees adjustments, if off I should have covered it.
.
Is the LNBF centered on the dish?-Yes.
Take measurements to be sure.-I have checked.
.
Look for manufacturers assembly drawings.-OK, will do.
Maybe you reassembled it incorrectly.-Well since the bottom arm had a bolt hole in the side, it was not a mix up. The only wrong thing could be left arm is on right and right is on left. Can not make any difference, they are the same.
.
If the dish isn't damaged or warped (string test?), I'd suspect you are not focused.-Would not think it is warped because Pixl had it in use.
?..

...And as for having LNB in the wrong place, a focal calculation shows it where it should be. Even checked that to extreme.
Very odd.....?

Here is a couple photos of mine. I have two one with an Invacom Quad and the other with a invacom universal mated to the original feedhorn. Both work perfectly.

I cant post pics at the moment either from my IPAD? Since I updated to IOS7, it been crashing alot.

Here is the manual for the .90, 1.0 and 1.2M Channelmasters.

Ok, switched to Safari mode... Sorry the picture is turned 90 deg. Happens from my IPAD sometimes.

I've used several different lnbf brands on mine, even those old H/V-separate output original lnbfs, they all work fine. Sounds like your aim is off, elevation off , or some parameter is off. I'd put that lnbf back on that you found PBS with, and try tweaking to the max with that, then maybe try one of the others, or whichever one you wanted to use on it. If it's the round primestar, you may check the lnb-support arms that fasten back inside the dish's edge. I've had one of those that looked correct, but the bolt was loose that secured it, and it had slipped back inside the dish by an inch or so, throwing off everything.

That LNB is almost like the one that Pixl had in the picture he sent me. Maybe the CM just need something BIG to work.

Here is the manual for the .90, 1.0 and 1.2M Channelmasters.

Will check that out.

Can not happen with this one. Bolts go through dish into the nut mounted IN the arm-both ends.
Tried all the above.

sounds silly but pop the end cap off the lnb and make sure there is nothing yucky inside.

Mine are the same way. Bolts through the back into the arm strut and you cannot screw it up...

Therefore you have another problem... AS suggested above, double check your elevation and STB settings. Course its really hard to have the elevation off on both my channel masters as the bolt has a pointed indicator on it which makes setting the elevation very precise.

Check the bolt that secures the bottom LNBF support to the dish is not a "set screw" in function. It goes through a hole in the support. If the lower support is not in place it will throw everything off.

 

[primestar31]

Did you remove the arms to fit it in your car, and maybe get them put back in the wrong places, or reverse them?

It's been so long since I messed with mine, that I don't remember if it's possible that they could be in the wrong locations, and change the focal point location.

It's already too dark for me to go out and look to see if that's possible...

Here's Jim's original pic of that dish:

Screw is in the hole. Other end at LNB holder is also in place.

Did you remove the arms to fit it in your car, and maybe get them put back in the wrong places, or reverse them?-Left and right are the SAME. Bottom never cam out of the LNB bracket.

That IS the dish in my yard on a pole.....Picture now in my first post at my house. MS got pics working again.

So we have determined it's not the dish or LNBF. This is not your first "rodeo" so we can assume you know how to aim a dish. Must be the cable and/or connectors.

I use a 1M Channel Master on PBS. The feed supports are foolproof... There is no way to install them incorrectly.

I have a stacked Dish FSS LNB mounted on the C-120 flanged feedhorn. No problems at all, and the dish has been in service for me since 2005. Elevation gauge is spot on accurate.

After the first two attempts, I thought the same. So I have used at least three different cables on my meter. I checked the meter on another dish that is setup and the meter is OK. See below for what may be the answer.

I am getting the thought this dish "wants" only a certain LNB setup. I ordered one from IMPAKT made just for the Channel Master dish. If they ship today I should have it on Wednesday. Better get this working with Winter on its way here in cold, cold Michigan.

I'm mystified as to what is not right here. I last had that dish pointed at 103w with the odd skew for the NBC stuff and it performed well.
What meter are you using? Everything on 125w is S-2 except one weak TP. If your meter doesn't get S-2 signals you will have a hard time finding this sat. Maybe take your receiver and a small tv out in the yard.

EDIT: A post by "northgeorgia" says

The old SD Channel 6, now with label "KNME SD," 12171 H 4443 (my numbers might be slightly off) is the only DVD-S channel left, but with Dolby Digital Audio. It is also an extremely weak transponder these days, barely registering 58Q on my microHD (this is when Oklahoma, Montana, and the other SD and HD feed channels are pretty much at 65 - 70Q). Used very rarely for feeds, too.
