I have a 3100 and 6000 connected to a 20inch dish and both satellites give me different reading on transponders.

For instance:

3100 Transponder 11 = 99%
3100 Transponder 28 = 51%

6200 Transponder 11 = 88%
6200 Transponder 28 = 44%

The problem is I can not watch any programs on the 6200 when they use transponder 28.

Any suggestions?
 
OK, your second reciever is either a 6100 or 9200, I guess.

What happens when you swap receivers around.?

What kind of switch are you using.?

Do you have any spare ports.?
 
The 82 and 91 etc are the longitudinal locations West of the 0 degree Greenwich meridian.

The numbers go HIGHER as you travel East to West across the country.

So if you stand facing SOUTH, 82 is more LEFT than 91.

Since the signal hits the dish centre and reflects back at an equally incident angle, in the case of dual or multiple LNB dishes, then the opposite occurs, that is the 82 LNB is now on the RIGHT side when viewed from the back of the dish facing South as before.

If a bird is directly SOUTH as would be the case if it's position coincides with YOUR specific longitude, the it will be at it's HIGHEST point of elevation in the sky.

As the birds go farther East/Left or West/Right then their elevation lowers.

For example, since MY location is ~ 114 West, the the 82 and 91 are well East/Left of due south, the elevation differences form a SKEW.
The 82 is 24 elevation and the 91 is 27 elevation, so you can see the slope of the dish lower left to upper right to accommodate them.

Think of all the birds visible from your point on the horizon as an ARC with the highest point due South and rolling off each side.
 
I am using the switch that came with the 6100 (my mistake not 6200).

No extra ports.

But I will try and swap the cables and see what happends and post back.
 
Some transponders at 91 degrees operate in bridged mode at 240 watts instead of the normal 120 watts. Even a poorly aimed dish can give high signal strength on the higher power transponders.
 
Hopefully this will help...

I went through all the transponders on both receivers and here is what I have found.

*Note: My 6100 had similar results but -5% on the signal

A 50% difference between the 2 transponders is not normal.
Maybe your dish is aligned on the border side.
 
I had similar issues when I had bev too. I was using a DP Quad LNB, so all the switching was done, and I could hit high 90's even sometimes 100 some some transponders and then I had some hitting like 60's,, I had tried diff ports, even a diff box but was pretty much the same issue. Bev is using 4 birds in total, my best guess is half the transponders are on each bird, and one of those birds must be weak or something.
 
Similar to my numbers. Check transponders on 82, then swap the LNB's and compare them.
 
If you are using SW21's, which I think you are, then as it is the even transponders that are low, you must have a partial short on a line somewhere.

Check all connectors, replace them if there is corrosion etc.

Have you tried to install a splitter on any of the lines.?

It is doubtful that it is an LNBF issue, or BOTH switch's for that matter.
 
Yes I belive it is the SW21. From what I recall that is the switch that came packaged with the system.

Where would I install the splitter? I already have a couple on hand so I can try that, just need to know where in the line I should install them and what I am looking for after.
 
Okay. So in theory, if you swap the lnb's, you should gain good reception on all transponders on 91, and your evens on 82 should decrease (similar to how your current 91 is).
 
When you say "swap LNBs" do you mean moving the whole Sat 91 LNB into the spot where the Sat 82 LNB is now?

I disconnected the two leads into the 91 and swapped them and mad sure they were tight. No difference.
 
Yes, physically remove both LNB's and put them in back in reverse.

Swapping the leads like you did won't do much. I think you may have a weak LNB like I suspect I do. My new one is on the way, so I will know for sure hopefully by this weekend.
 
Ok I swappped the LNBs.

Now my 3100's transponders are all in 85-100%

But my sat 82 (HD) have all the even transponders around 50 or less.

I guess my LNB is bad?
 
Maybe I should have been clearer, I was wondering if you HAD installed a splitter as this is the problem that is seen when a splitter is installed.

Splitter CANNOT be used on Satellite systems in normal installations.
 
I am having the exact same problem as you, except ALL of my even transponders on 91 are weak (40-60%).


I was having troubles with my 82 signal, so I went up and repositioned the dish. I sacrificed some 91 (down from 94% to 86% on T11), but my 82's are up in the 80's now. BUT now my 91' evens are low.

I just remembered I did switch the lnb's around before I repositioned the dish, but didn't notice much. I am wondering if my original problem with my HD reception was that my 82 lnb (which is now my 91) wasn't getting a good signal on the evens.

I guess my question is, can an LNB be defective on just the odds, or would the odds/evens both go out.

Ugh, time to go record some levels and switch the lnb's around.

SensFan, didn't mean to hijack, but we may have the same problem.
