    Steve, what test are those results from? I've never seen that screen in your screen shots.

    azarby, I'm not sure exactly which dish I have... my signature is just from what it tells me in system info. Hopefully D* will be able to tell me when I call later.

    It's way too early [lack of info] to know very much. "Generally" the bandstop filter, while needed, seems to also be a weak point too, because it [by design/function] causes the DECA signal to return back into the coax system. The SWiM-16 has the crossover to the other leg and this reduces the "return" [since when it does return, it's gone through the whole other leg and come back, so the level is way down in power].

    Must I take you out to the wood shed? :nono: :lol:
    SWiM & DECA have NOTHING TO DO with each other, other than DECA needing to be on a SWiM system.

    OK, I see a newer post in here which tells me how to run that test. Will do so right after a recording is done.

    It looks like I only have 1 cable coming from the dish. In the attached picture of the SWM PI, the wire coming into the house connects to "POWER TO SWM" and then there's a cable coming out of "SIGNAL TO IRD" and going into the 8 way splitter (also attached). From there, I have 4 cable runs to receivers, a 5th run to the broadband DECA, and the top 2 connections just run to unused wall jacks.

    The splitter does have a green label on it. I'm assuming the SWiM-LNB or SWim-8 (probably the SWiM-LNB) have the green labels on them because the tech knew to use a green label splitter before I even said anything. I can't tell if there's a band stop filter on the line coming from the dish into the house and I'm not real thrilled about getting onto my roof so I'm going to see if the other steps suggested here will help first.

    wow, has this topic gone into new areas since "problems activating an HR24"! ;)

    That's not quite what the context is here IMHO.

    So... if it needs to be on the SWiM system...and in this case a DECA is apparently attached at some direct connection point...doesn't an installed DECA unit connected to a router still require some "bandwidth resource" from the SWiM itself that somehow impacts the overall capacity of the SWiM unit?

    If no...that is good and definitive information to know.

    SWiM uses a 2.3 MHz comm signal and the band above 970 MHz.
    DECA uses the unused 500-600 MHz band.
    SWiM doesn't know or care about DECA.

    Looking at what you have, it seems fine and it appears that you have a SWiM-LNB along with a SWS-8 splitter. The only thing I see is that it does not appear that the open port on the splitter is terminated. VOS would know for sure, but I believe any unused ports need to be terminated.

    OK so what is starting to surface is:
    SWiMLNB [with green sticker],
    An open port on the 8-way splitter than needs a 75Ω termination,
    Two unused wall jacks that are also connected, but aren't terminated.

    It sounds like I should start by disconnecting the two used coax runs and terminate all 3 open ports, is that correct? Will D* send those to me if I call and ask?

    Not sure about that, but the installer should have done that. You might want to just call him up and see if he'll drop them off.

    DirecTV won't send them to you, but the installer should have used them.
    As Merg said call him if you can, otherwise you can get them at Lowes, Home Depot or places like Radioshack, and they should be very cheap [since they're nothing more than a resistor mounted in a connector].

    Now without any of these, you might just disconnect the two unused lines and then rerun the system test and see if it passes.

    "I imagine" the open port(s) on the splitter have much less affect than the cables are having. This gets into the phase change of the signal as it travels through the coax. Inside the splitter, this distance is so short, there is little change in the phase.

    Terminating the cables at the wall plates, in the long run, should be even better than termination the ports on the splitter.

    I switched the HR24s and I'm still getting the dish alignment error (on both of them) but the "reduced network performance" error is gone. Should I swap them back and run the "Guide & >" test to get the readings, or should I just be happy I'm no longer getting the error and be done with it?

    As VOS recommended, unhook the two cables that are not being used and see what happens. If that doesn't work, get the terminators.

    I just disconnected them and still getting the dish alignment error. I'm not getting the reduced network performance error anymore, but that stopped as soon as I swapped the location of the HR24s. I'll give the installer a call and see if he can give me those terminators.

    Yesterday's tech did say that one transponder wasn't getting a reading but he didn't think it was a problem. I wonder if that's why I'm getting the dish alignment error though. My SWM transponders read as follows... is this perhaps the cause?
    99 0 0 98 97 83 0 92
    92 N/A N/A N/A N/A N/A N/A N/A
    N/A N/A N/A N/A N/A N/A N/A N/A
    N/A N/A N/A N/A N/A N/A N/A N/A

    And is there any purpose for the black rubber things the last tech put on the ports of the splitter other than to force me to use a wrench for every single turn? It took me about two minutes to get each one off instead of 10 seconds!

    SWiM's reserve tuners. The broadband adapter is not a tuner. It's a network device and only counts against the DECA limit of 16 network devices per cloud, and not the SWiM limit of 8 tuners, in this case.

    EDIT: Apologies to Merg. I see he replied first. :) And to VOS. :)

    That's the "Phy Rate Mesh" test I ran on my HR24-500. You hold down the HR24's front panel GUIDE and RIGHT ARROW to get to that test screen. It's a little tricky to get the test screen to come up, but it will. :)

    VOS replied on this already in another, somewhat-related topic thread.

    It still doesn't explain why the migration of the DECA supporting the router connection from the SWM1 8-tuners-already-used splitter to the SWM2 splitter resolved a couple other users' issues with tuner-conflict blank recordings...but hey - it worked, so everyone's happy.

    Glad yours is working to your satisfaction as well. :)
