    it does sure looks like you have a SWM LNB and not a SWM8 switch

    Is there a way to look at the dish and see what LNB version is installed? Pictures someplace? There appear to be 4 cables coming out of the dish, which is what made me assume that it was an external SWM. The installer had some difficulty getting it to work.

    Would a SWiM LNB upgrade leave the old F-connector block on the dish?

    No way visually other than the tell-tale sign of only one line coming from the dish for a SWiM LNB. But since there are four lines you would need to remove the LNB to see if the additional lines are actually connected to it or just tucked inside the LNB arm,

    Short of that you're going to have to trace those lines from the dish to actually see where they terminate to be sure.

    Then at that point you're going to either find a SWiM-8 module there, or a maybe just a 4 barrel ground block with only one line connected to the opposite side of one barrel which couples one of the lines (which is the one that must be connected to the LNB) from there inside the home to the point where the splitter ---> PI are in the attic.

    So, I went up and looked. While from the ground it looks like 4 lines, two are actually no longer connected to the LNB -- which reads "SWiM" on the back. Strong clue. Inside the attic, near the power adapter and splitter, one cable of a dual-cable set is unconnected (and was probably unconnected inside the LNB arm). I assume that was one of the two connected to the dish, leaving the one line down.

    So, the problem isn't heat as I thought (or at least not due to a powered box under a foot of insulation). I'll test the couplings now.

    Thanks all.

    Well at least you have extra runs of coax in place to test with.

    I currently have 4 HD DVRs (2-HR21s & 2-HR23s) and an old SD DVR. I am looking to add a Genie, and eliminate the old SD DVR. My current DISH is a Slimline 3 with four wires connecting to a Zinwell-16 Multiswitch. What are the installation options to wire a Genie, and my other 4 HD DVRs? Is using a SWiM-16 the only option, or can the installation be achieved with a Slimline SWiM dish with one wire & other SWiM spliters?

    Thanks,
    Dave

    Since you will have 13 tuners you only option is a SWM16, but this should be a simple swap since you already have the four lines from the dish

    One final questions, is there a limitation on MRV? Since I'll have 5 units, I wanted to make sure all could be accessed.

    Thanks, Dave.

    There is a limit, I don't recall the number but I believe you are well below it.

    no more than 16 nodes and out those 16 only 10 can be HDDVRs

    Yeah, MRV uses the MoCA 1.1 protocol (on Band "E" for DIRECTV) which can have up to 16 nodes.

    However, that doesn't mean the UPL produced by the DIRECTV software for WHDVR service as a higher level protocol that runs over MoCA will be able to see the playlists of up to 16 host HD-DVRs on the MoCA network from any one receiver.

    Yeah, I IIRC 10 is the "sweet spot"

    A follow-on question - I currently have a Zinwell-16 Multi-switch for my 4 HD DVRs & one SD-DVR. Is there any advantage in changing to a SWM-8 switch other than eliminating BBC connectors, and reduction in coax cables to each HD DVR? My current DISH is a Slimline 3 with four wires connecting to a Zinwell-16 Multiswitch.

    Thanks, Dave

    You hit it on the nail as for some of the advantages. You'd also be able to switch to DECA for Whole Home and could start using the newer receivers, such as Genies and minis along with the H25. Don't forget with your setup, you'd need to put the SD-DVR on the legacy ports as you'd be using all 8 tuners with your HD-DVRs.

    I have a question. About three months ago I swapped out a self-installed SWM8 for a SWM16 in anticipation of upgrading my main receiver to a Genie. When I swapped out the SWM8 I just took the line with the main receiver/PI on it and put it on SWM1. I moved the 4-way splitter with the other two DVRs to SWM2 and brought the system and the receivers back up. It worked fine so I left it alone. Sunday DirecTV came with an HR44. It was pretty much a "plug and play" installation for the tech. He did look at the SWM16 but he was more interested in making sure the HR44 was on a SWM connection that not exceed the tuner limitations. He didn't say anything about moving or isolating the PI. So since I have some downtime during Thanksgiving to mess around with my setup is there any benefit or reason to isolate the PI to the separate power input on the SWM16? I should add that I have as many receivers (3) as we're ever likely to get as there's just the two of us and we rarely get visitors who would want or need access to our full DirecTV service.

    there is really no technical reason, as long as everything is connected properly. What I mean by this is, as long as you are using RG6 SCC, and is not too long, then there is no difference.

    Thanks. Indeed it is installed properly in terms of RG6 SCC and the distance is 20 feet of cable run from the PI to the SWM16. It's been up and running first with the SWM8 and now the SWM16 for five or more years without any issues or problems so I'll leave it alone for the time being.

    so you should be in "good shape" changing it would be more like being a "perfectionist" which there is nothing wrong with that

    Oh me.....you used the magic word...."perfectionist". That probably means once Mrs. K goes back to work Monday I'll be in the attic. :righton: My equipment board isn't nearly as sophisticated as some I've seen pictures of on this board but I try to keep it neat and labeled. The DirecTV tech either hasn't seen many installations or maybe just the luck of the draw but he actually asked me if I'd done it myself or had an outside tech do it. Made me feel good but also makes me wonder what kind of "messes" he'd come across.
