VOS-

Just read your sticky on splitters and am looking for some hand-holding here when I get my parts.

OLD SETUP-

dish---->SWiM8---[coax 1]--thru roof--->PI---->HR24
....................|
....................|
.....................----[coax 2]--thru roof--->2-way splitter--->HR21
.........................................................................|
.........................................................................|
..........................................................................----->HR21


NEW SETUP (proposal 1)-

dish/SWM combo--->2-way splitter--[coax 1]---thru roof----PI----HR24
............................................|
............................................|
.............................................--[coax 2]----thru roof-----2-way splitter--->HR21
...................................................................................|
...................................................................................|
....................................................................................-------->HR21

(proposal 2)

dish/SWM combo--->-[coax 1]---thru roof----PI----4-way splitter---HR24
..........................................................................|
..........................................................................|
...........................................................................------>HR21
..........................................................................|
..........................................................................|
...........................................................................------>HR21


Is either proposal better than the other? Perhaps #2 because it would have 1 fewer splitter exposed to the environment? Perhaps #1 because it would allow the HR24 (which is the furthest away from the PI), to have 1 fewer splitter upstream?

Thanks

The goal/idea of this is to balance [maximize] the power at the end of each coax, while working within the coax structure in place.
The only real difference I see between #1 & #2, would be "if" the HR24 has a 50' longer coax than the HR21s. If this is the case then #1 would balance better. If all the runs are about the same, then there really isn't any advantage, as #2 would work and the "imbalance" with #1 would simply mean the HR24 would get slightly higher signal.

Thanks for that.

In fact, the HR24 is probably 50 ft or so further away than the other two units, so I will stick the first 2-way splitter on the roof (proposal # 1)

Still waiting for my parts which should be here tomorrow. I've recorded a bunch of things between 11 PM and 7 AM and found that I get 771 errors on these as well, so I'm thinking there might be something cold-related. All the problems seemed to start when our evening temps dipped below 40 and were worst when below freezing. It will be interesting to see if things are solved by the replacement SL5-SWiM. If I have the same problems after, one will probably be able to hear my F-bombs from many miles away!

Well new SL5-SWiM installed without much fanfare, but I'm afraid I wiggled the dish a little too much and will probably need to have dish signal peaked again.

Before:

101 ----- 95-96%
110------95%
119------85%
99c------86%
99s------not acquired
103s-----not acquired
103ca---81%
103cb---89%
swm-----99%

After:

101 ----- 95-96%
110------95%
119------80%
99c------82%
99s------not acquired
103s-----not acquired
103ca---73%
103cb---85%
swm-----99%

Most concerning is the 103ca and 119. I hope I don't lose any local HD. Everything seems ok right now.

Will keep an eye on my old zero-ing out problem on the transponders. Hopefully, replacing both my old LNBs and SWM-8 will solve things.

Will update status as necessary.

What's the deal with D*? I call them and tell them I've swapped out the LNBs and have lower signal strengths (as posted above) They tell me that they are perfectly adequate and won't schedule someone to come out and peak the dish. Instead they want to troubleshoot me over the phone. I just hung up because the service rep had to put me on hold (for over 5 minutes when I hung up) because I had the temerity to say that I would gladly pay for a service call. My local guy came out once for $89. I figured going through D* this time would be slightly lower or even free. Did I break some sort of service agreement by swapping out the LNB unit on my own?

And you still wonder why DBSTalk is here, alive and well? :lol:
I think there is a 70% cutoff, where above they won't and below they run your through a bunch of hoops before they will.

In other words, my 74% should be 69% ;)

you could always throw a wet blanket/towel over your LNB and give them those readings. :lol:

It has to be asked:

Are there any good youtube or other tutorials out there that would let me do this by myself, maybe with the wife watching the signal strengths on the tv while i'm on the roof? (i.e., no BirdDog or anything else) Or just too much hassle to learn?

First question would be "how well do you communicate with your wife & she you?" :lol:

Really, tweaking the dish isn't that hard.
I find it easier to setup a receiver & display that I can see from the dish.
With the SWiMLNB, your need to "detune" to one side to "a number", then move the fine adjuster the other way, counting the turns, until you find "the same number". Then divide the number of turns by 2 and turn it back this amount. This has now split the distance/angle between the two equal "detuned" points. Do this for AZ & EL.
You need to loosen the locking bolts/nuts for both the AZ & EL, and then use the fine tuning screws that should have dials on them.
"And then" remember to lock things back down.

For me these adjustments are so much easier than the part of yelling to find out what the screen is showing and trying to get a response [and why I setup a receiver & monitor].

YMMV :lol:

Sounds easy enough...but I know myself and I WILL screw it up. It'll be money well spent to have someone come out. I think this time I'll watch the tech do it (even if he's using a birddog, or whatever) and in the future i'll be more comfortable trying it myself

Not trying to hyjack this thread, but I have scanned through 5 pages looking for the final solution.

I too, am looking to solve a similar problem. After about a year of use, my SWM 3 with 8 way splitter has started intermittently loosing connection with receivers. So far, I have seen it at different times on 3 DVR's and 1 receiver.
I am using three DVR's and 3 receivers with one of the DVR's set up as a single line so as not to exceed the 8 ports.

I have, so far replaced the splitter without improvement.

I have a spare SWM 3 in my RV and after reading all the posts my next move is to go get the other LNB and bring it home to swap. I'll post results.

Thanks for all the info above.

As far as swapping the LNB, the Slimline 3 aligns exactly the same as the 5. I don't think you will need to worry about changing the dish setup unless you trip over it. It's not that sensitive and if it were it would have already been moved by wind.

I was having a loss of tuner problem on my HR20. I found the problem to be the center contact on the coax female connector on the receiver wasn't making good contact with the copper wire in the cable.

HR20-100 s/w version 0x087f
au9 dish NO multiswitch or diplexers.
Internet connection via WIFI.

Well, I changed out the SWM LNB. No better. Found a corroded connector exiting the PI to the LNB. Changed. No better. Next step is to go get the PI from the RV and swap. The mate to the connector I changed could be bad.

Sorry you're having so many troubles. All I can say (As I have relied heavy, if not exclusively, on the expertise of others) is that you are in good hands here at DBSTALK forums. Hope things work out for you. It looks like you're going through possibilities pretty systematically.

Well I guess I finally got to the bottom of my problem. After swapping the 8 way splitter, the LNB and the PI without success I finally got to the last possibility, the incoming line.

BINGO!

So far I have not had any problems with sat signals since replacing the SWiM-LNB combo. No dropouts. No "cold" related issues, etc... It looks like tht may have been the problem. I'll give it a couple of more weeks before I put that problem to rest.

When I hooked everything back up on the roof, I took the cable from the roof jack (which had quite a bit of slack) and just threaded it up to the output at the SWiM-LNB. If get a tech out here to peak my dish, did I not leave the tech with nowhere to plug into my satellite up on the roof? I think I'll need to rewire to have some "point of entry" to the system without have to remove the LNB unit.

Additionally, I have fresh lines going to each of my AM-21 boxes to maintain OTA. Two of my three boxes now also have great working OTA. The third (one closet to the signal) only picks up the local PBS (and rather weakly) The other two boxes pick up everything very well (I have 10 mile line of sght to antennas. So when I get home I need to troubleshoot that bad boy (It never ends, does it?)

A week now without any problems. Did have some pixellation for a 3-5 second spell during the wife's viewing of American Idol last night, but other than that things have been good.
