12145 I get a 70-71 quality and the "we're moving so if you are seeing this ya better call your cable company slate"

12104 I get a 68-69 quality

This is on the Coolsat 5000 here in Minnesota

I wish I was getting those Q levels on 125. My levels are 40 or less just like 123. There are other sats that nearly peg the meter. I made some adjustments this weekend and only managed to get 1 or 2 extra clicks in Q.

This is on a Fortec Star Merc II and and an Azure Shine/3ABN 90cm dish in New Mexico. It figures, the two satellites I watch the most have the lowest signal strength.:(

note the Coolsat 5000 meter 63 is threshold
65-66 is a stable signal

I havent tried the Merc II but on the CS5000 123 shows
11720-72-73
11800-69-71

My true south is 121W and with a 90CM and a coolsat 7000 I get the following quality on 125W:
12104 53%
12140 87%
12145 82%
12163 62%
12179 89%

I've bumped the dish back and forth a bit and this is about the best. On satbeams I'm in the 47dBW region. On my Coolsat 7000 53% is a very stable signal. I think it will work down to 20% or so.

On 123W I get:
11720 80%
11729 29% (no stability issues that I have noticed)
11799 68%
11805 80%
12105 89% (12104 on lyngsat)
12107 50% (12110 on lyngsat)

It seems like 12110@123 versus 12104@125 for me are both weak. I would have expected 12105@123 to be weak and interfering, but it is 89%!

Anyway, both are very watchable here and it is nice to have RTN & PBS closer together than before. Though 2° is just a little bit too close. ;)

This is interesting, 123 and 125 both have transponders with the same frequency (12104). Wonder if that is why I am getting 0 Q on 12104 on 125. I am getting about 60% Q on 12180 on my Pansat 3500, with a threshold of 30, but 0% Q on 12104.

Does anyone know if elliptical dishes (mine is 39"X26'') are more likely to get interference from two adjacent satellites than round dishes?

Looks like it might be time to dig out the old engineering books.

we've noticed the farther east in the US you are the harder it is with the 2 degree spacing.

My 76cm dish gets both 125 & 123 just fine and the primestar (40x30) gets 12104 V on 125 just fine

try and bump the dish e or w to see if that fixes it

Thanks man, even though I thought that I already had the dish peaked, moving it slightly west worked. I had peaked the dish using 12145 H and 12180 V , and they were as good as I could get. Apparently, the 12104 tp on 123W was interfering with 12104 on 125W, and when I moved it a bit further west I could get 12104 on 125W. The Q is roughly 30 which is my min., but the picture is stable on Montana PBS, and even though this move to the west cost me a bit of Q on 12180, I still have very stable pictures there as well.

Thanks again, I might have eventually stumbled on this myself because I don't like go give up on something that presents a challenge, but your help gave the process a big boost and saved me from a great deal of frustration.

Now it's back to my BUD to see if I can get GPB on the 4dtv again.

i am thinking about trying this mount by digiwave:

Digi%203%20LNB%20Brkt%20Sketch.jpg


looks like you could accomplish quite a bit:

I've used most all of the multi-brackets, even the SatelliteAV dual with ultra-micro LNBFs and the best I've gotten is 4 degrees on a 76cm dish.
I still haven't set up my 100cm dish, but I did manage to procure a shipping pallet for it to sit on while I tinker. This was 3 years ago, however.

A monoblock, if one could dremel one out, could really work on a 120cm or larger reflector, but 100cm is pushing it and 76cm is out of the question (for FSS, not DBS).

Just curious that the USALS on my Merc II, goes right to 123W, 127W, 129W , but not a trace of 125W . Have to nudge it back east to get AMC21. Early times, yet, I suppose everything is not yet "set in stone" .
:)
AMC 21 wasn't in the menu on my TRAXIS 3500 so I took AMC 3 and put in 125 as it's longitude. Worked perfectly.

When will they start programming I wonder??? I get that message on the new sat and also on the old PBS sat before I changed it to 125w.

Iceberg, you ain't kidding about your first sentence. I programed AMC-21 and got excellent results! :)
BUT... :( It screw up me getting 123. Guess I gonna have to put up a prime dish just to get that bird.
Any suggestions?

Let me rephrase that, is anybody getting Montana PBS programming instead of just the message about the move???

All my AC3 PBS is fine but no Montana yet, just that message.

yep. Montana is at 12104 V 4340 now

and you should have kept 87W in there too...there is some interesting things on it

I'll keep looking for it, may have to do a little adjusting. Getting all the others but no Montana. Just that message about moving on 12145 H.
I'm thinking of making Star One into 87W.
As always, thanks.

Ok, Just swung over to 125° tonight and I'm getting 78-79% quality on 12104. 12163 is lower and 12145 seems gone completely. (I'm blind-scanning now)

My 123° transponders seem about the same. Anyone else see a change tonight on 125°?

12145 is gone....nothing here

12104 I am getting 69-70
12179 is 75

this is on the Coolsat 5000 meter with Winegard 30" dish

on 123W 11720 is at 75 and 11800 is at 73

according to the MOntana PBS website

Beginning October 6th, 2008, MontanaPBS will be available on a new satellite and on a new frequency. MontanaPBS will be moving from its current location on AMC-3 to AMC-21. We will simulcast on both satellites beginning October 6th, and cease service on AMC-3 on October 17th

I know last week there was the slate card so maybe it was up for a week on 12145 :)

Ok, well I've moved my dish up and down the arc a few satellites and always get 77-79% quality on 12104 @ 125 now. Maybe my motor / receiver wasn't quite getting it right last night. Needless to say jumping 23-26% in quality was a surprise.

Thanks for checking.
