If you've had multiple switches go something is either causing them to fail or the problem is something else. Did any of the techs move the power supply to another room/circuit in the house? Did any of them test power in your house?
Another quick and dirty fix would be to trade out the little antenna for a bigger one, like some rabbit ears. Bigger collector often equals better performance. Remove the attenuator too.
That's a blu-ray player you're trying to get to program? IMHO I wouldn't bother. The dish remote is only barely functional with that sort of thing and you're better off using the Sony remote for it. I wouldn't even suggest a Harmony, the Sony remote is just better for the blu -ray.
If you're cool about asking, especially before I get the dish up, I'd probably do it for nothing, were I the tech coming to your place. It depends on the tech.
The dual tuners have a different software suite and report signal strength differently. I find it's usually about 10 down. So long as your signal on transponders 11 and 12 are both over 85 you'll have no problems.
Someone is mistaken here, you can't simply replace the combo lnb with a dual and make it work.
The two issues to cover here is 1) you have to use an FSS lnb and 2) the FSS signal is weak so you need something sizeable to collect the signal. I think a 24" might be big enough to work but the...
With the new 1000 dish we picked up 129 at 68 just last week from Portland, Or. I'm skeptical since the dish was on a rubber non-pen mat and not peaked with the 129 lnb. I'm willing to bet it would have been in the low 80's otherwise.
The problem is that installers are really the ONLY link as to whether or not the work gets done. Therefore it always comes back to the tech when something goes wrong. In this case, there are several answers which could have been investigated and applied. Why didn't the tech do it? There are...
I've run into problems with DPP Twins and 942, not too often but sometimes I just can't get them to work together. I'll always opt for running a second cable at that point, replacing the DPP with a legacy or dp twin if I have it.
You guys are dogging me for mentioning weather sleeves? I'm simply telling you what would happen if you were QC'd by our guy. It's recommended by the fitting supplier (PPC EX6 fittings) to keep water from wicking in the threads. Not that it matters, you all seem to know everything already anyway.
You can use a regular DP twin to run your DPP44. I've done it plenty and it works fine. Without seeing your setup I'm assuming you have the switch installed properly including power supply and inserter. The DPP44 seems to be a finicky switch to use. If at all possible I'd try to get another...
I think the most important point is to make sure there's something to keep the post from spinning in the ground. One easy method is to drill a hole in the pole and insert a piece of rebar. Once it's buried it can't turn and it can't be pulled out either. I've also seen the end simply bent...
No weather sleeves on any of those outdoor connections, I'd be failed on a QC for that. Other than that it all looks typical. I assume the PVC you're talking about is at the base of the post where the lines are heading underground? Hopefully it's one piece that goes all the way to the house...
Sounds like your 811 is toast. However, to test that you could place your 811 where the 311 normally goes and see if the problem continues. If so, replace the 811. If not, then there's a problem elsewhere, perhaps the switch, fittings, cable, etc.
Also, your spotbeams will be much higher strength than the others. So even if you 90 on T-1, all your others will probably be weak. I know in our area if the spotbeams aren't maxed out the dish is out of alignment or something is in the way.
What type of lnb are you using? I've seen DP and DPP lnbs have problems with the 811 that are software oriented, so a new receiver may or may not have the same problems. Personally I use a legacy twin with my 811 and have never had a problem.
