92XX series installation:

92XX/94XX Installation 101 - Canadian TV, Computing and Home Theatre Forums

Having read the topics of attaining satellite 82 after receiving satellite 91 the consensus seemed to be to find a strong signal on 91 then using your skew to find satellite 82. I have tried for five days between work (no luck). I have got 82 but lost 91 in the process. Anyway is there anyone who has been thru the same problems and how to attain Sat 91 and 82 at the same time. If so is it possible as a scenario to state something like yes we had Sat 91 then moved the Skew 14 degrees clockwise or something. I think this would be more informative than to just move your skew and hope you luck out.

Thanks,

EnC

Just checked and tightened some cables and everything is working as it should now.

Using the closest receiver, I would disconnect the receiver at the switch and perform a check switch with no connection. Then I would connect the receiver to the " to receiver" connection of the power inserter and then perform another check switch.

Thanks again. I Followed the above instructions and now both receivers are working. However, I only have satellite 82 and high def channels on the shorter cable run receiver and 91 and SD channels only on the longer run HD receiver? Also appears that the longer cable run picking up 91 isn’t seeing the DPP 44 switch ? Any ideas? Thanks

The issue with the shorter run is puzzling, especially since both satellites show up on the scan. The issues with the longer run could be due to cable loss. More troubleshooting is required. What happens when the receivers are switched? What are the results with a 4100 receiver? What are the results with the line amp, which must be DPP compatible to work properly, connected to the switch output going to the most distant receiver?

Is it possible to test the receivers with a known to be working dish installation elsewhere?

I haven’t tried switching the HD receivers since installing the DPP44 switch. The SD 4100 receiver is connected directly to the #3 port of the DPP LNB and picks up both 91 and 82. When the SD 4100 was connected to the DPP switch 44 it would not work? I am not sure whether the line amp I tried is DPP compatible? Does it matter which 2 of the 4 ports at the DPP LNB are used to bring satellite signal to the switch? Please see pictures of line amp and 4100. Thanks again!

The ports used on the DPP44 LNB should not make any difference. The reason to connect the 4100 to the switch at the same location as the other receivers is to help diagnose the new receivers, switch and wiring. Trying the 4100 on another switch output might help as well.

That amp seems to be DPP compatible as it is rated at 950MHz to 2300MHz.

On second thought, there may be an issue with the line amp. It needs to pass DC from the receiver unchanged. To do that it must be powered separately or use the receiver's power and pass it through. I couldn't find any information on that exact amp but there are similar amps made for DPP so it's unknown if it is fully compatible.

Here are the specs on the inline amplifier: Dr. Sat :: Satellite, OTA, Towers, IPTV & Internet services it seems to be compatible so the amp itself may not be the issue

Ok Thanks! I actually tried the DPP 44 Switch installation with and without the line amp. It didn’t seem to help with either scenario. My last update with pics did not have the line amp installed. The DPP switch 44 did help getting the new receiver to pick up 91 with 100% signal strength on the long cable run. I just don’t understand why it can’t pick up 82 on the long run? Also not understanding why my other receiver with the DPP switch 44 now only locks on to 82 and not 91? Wondering if I just need to go back to using the DPP quad without using DPP 44 for the HD 6500 and SD 4100 and then mount another dish to eliminate the long cable run to the other new HD 6500? This is how it’s currently connected.

I don't see any issues with the connections. If the 4100s work then it must be an issue with the new receivers. Someone on site will be better able to diagnose the issues and get it working. I'd still recommend a second dish if that is possible. 250' is about the limit for RG6 with typical satellite equipment. It's quite possible that the frequencies used for stacking with DPP is causing signal loss or other issues.

Thanks a lot for all your help and advice! I appreciate it and will let you know when I get it figured out. I’m thinking a new dish for the long cable run might be the way to go. Due to surrounding trees I might have to do a remote post mount. Is mounting to the base of a large cedar tree a bad idea? What’s the best conduit to run the RG6 back to the building with the receiver?

ExDilbert

Mounting on a tree is not the best for the tree but would work. A 4x4 wood or a sturdy metal post the same diameter as the dish j-mount might be better. Be aware that the dish does not need to be mounted very high up, just high enough to avoid temporary obstacles such as snow drifts, vehicles, animals, humans, etc.

I usually use 1" black PVC or larger for small cables. Smaller conduit might work but conduit that is too small increases friction and the possibility of cable damage. Larger conduit may be required for more than two RG6 cables. Black PVC conduit is usually available in up to 100' coils at plumbing or building supply stores. Direct burial cable is another option but is more susceptible to physical damage.

Hi I have been reading through the posts try to fine someone with a similar issue. At my cottage I have the following setup. One BEV Dish with two LMBs each with a single cable running direct to a BEV 9400.

Plant Tree Street light Biome Woody plant

LMB 91 is on Stat 1 input on the receiver LMB 82 is on stat 2 input. No switch. Cables run direct from the LMB to the receiver
Running a check switch produces the following

But I get this message

Do I need a switch then the separator?

I know the receiver is good be because it works a home. Also I have done a factory default reset as well, then run the check switch with the dish not attached. Then attached the cables and ran the check switch again.

any suggestions on what I am doing wrong?

Thanks

You need to swap the 2 single legacy LNBs to one dual DPP LNB. You should be able to pull the two off and put the DPP on without needing to align the dish.

I apologize in advance for lack of detail as I'm investigating a satellite TV problem at a family cottage, and it's something I know nothing about. Also had no data there, so I'm going from memory now that I'm back in "civilization". (I don't have the box/dish details, but my question is generic, hopefully.)

Owners started getting iffy reception on channels, then only a handful of channels would work, then ultimately nothing. Visual inspection of cables seem intact, and view of sky was cleared of branches, even though dish had a very clear view to begin with. Owner tested signals (prior to my arrival) indicating strong signal on satellite 91, but middling to nothing on 82.

We then replaced a feeder (2 of them at base of dish), but no change. Swapped all 3 with no change, so presume they work. Tests of the signal during these swaps showed 100% solid on 91, and 0% solid on 82 on all transponders.

Looking back, that in itself seems odd to me. Is it even possible to always have 100% on 91, for hours? I would have expected some minor dips, especially as you change transponders. Makes me wonder if the problem is at the box itself.

Next part on order is a "splitter", or more accurately a "combiner" in my view as it appears to take the signal from the 2 feeders into a single cable into the cottage.

Sorry for the vagueness - would love any advice folks can give here. I am out of my element for this particular tech.

Is there an obstacle, such as a tree, that is blocking line of sight to 82 but not 91? The symptoms seem to indicate that.

Thx for the response. A consultant came out before I arrived, and they cut down about 20 branches in the area they recommended without change. They're considering hardware changes at this point, and we bought a feeder in the meantime and swapped it out, also without change.

What's odd is that they had a perfect signal last week, then spotty, then nothing as of yesterday. Maybe a loose branch has fallen a bit into a bad position, but we can't find it.

Is the mount solid? If mounted to wood and the wood starts to rot the mount and alignment will go out.
It does sound like tree growing blocking the signal.

ExDilbert

· #2,639 · 10 mo ago (Edited)

I must have glossed over the bit about already checking obstacles. A week or two is a little short for trees growing as well. I'd agree with checking the stability of the dish and the aiming. Checking connections and cables for damage, water ingress and corrosion would be the next thing to check. After that I would be looking at hardware such as the LNBs, switches and receiver. It sounds like there is a SW21 combining 2 legacy LNBs. Swapping the LNBs would determine if one is bad. Swapping inputs into the SW21 might indicate that is bad. Last but not least, the receiver could be failing to provide the right voltage levels for the switch and LNBs to work properly.

Thanks for all the ideas. I think the LNB is what I referred to as the feeder initially (there are 2 of them at the base of the dish), and we swapped them out. We hadn't checked the aim, and there def could be some cable damage we haven't found. An SW21 is on order too. Looks like plenty of things to check, including a branch we might have missed.

Appreciate all the help folks.
