    What happens when I add 2 HR24s and an Hr44 (9 tuners) to a SWM8? Does it just not work? Or does it depend on which power up first? Suppose I power up the HR44 first, then the HR24s. Would I get 5 tuners on the HR44, two on the first HR24, and one on the second HR24?

    Generally it will depend on what powers on first but that may not be the case every time. The only way you won't have various weird issues is to disable one of the tuners on one HR24.

    Sounds like it is time to upgrade to a SWM16. They are not that expensive.

    I remember looking at that months ago, and didn't think it was possible to disable one tuner. I will look again.

    Thanks for your response.

    I agree with Josh, get a SWM16, just make sure to not overload one side.

    It is possible to disable a tuner on an HR2x, it is not possible on a Genie. The feature is really more of a holdover from the pre-SWM days.

    DPeters11 and Slice1900:

    I currently have a SWM 16 and I am using 13 tuners across multiple receivers from a dish on my terrace here at my condo. The issue is that my sat dish has to come down because of a construction project and I will have to temporarily use the feed from the Condo association that is only one coax and limited to eight tuners. There is a rumored SWM 31 that will ulitmately solve such a problem, but it is rumored for next year.

    I understand through an additional search that I can disable a tuner during setup by the way. I actually have an HR21, HR22, HR24, and an HR44 that would be involved in this exercise. I assume that I can disable tuners as required via setup on all these models?

    You would be able to go single tuner on all except the HR44.

    You'd get a 776 on one of them when you have all on. Like dpeters said you can switch some to single tuner. Settings-satellite-repeat Sat setup

    yep, nailed it. it does not really matter which unit comes on first, you would keep getting 776 on all the units randomly as the receivers try to get the correct amount of tuners required unless of course you limit how many tuners they are allowed to get, which as noted is not possible on the Genies

    SWM13 isn't an option in this case. He had a good setup, on a normal basis, this is a temporary situation for him.

    To all:

    I will run with the HR44, an HR24, An HR21 with one tuner, and a three of CR41 clients. The construction project will last into Spring 2016. If the SWM 31 comes available, the condo DirecTV supplier has committed to install it on my leg of his infrastructure. Then I may not reinstall my dish. We shall see.

    Thanks guys for all your input.

    What makes you think there will be an SWM31?

    See this thread, it was a Digital SWM30. Not clear what it is, but mentioning it with D2 Advantage means it is targeted at MDUs.

    The rumored SWM31 will be non-partitioned and available early next year capable of supporting 31 tuners on a single coax. That is all I know. My source is President of a company servicing apartments, condos, etc for DirecTV.

    On a single line? Not even two? How would they manage that? Slice has done the math in the past that showed they should be able to get around 24 or so maybe. Interesting.

    They can get 23 or 24 using the DSWM's current spacing of 51.03 MHz. If a next generation DSWM chip uses a larger FFT it can filter better. In fact, you can filter as sharply as you want, to filter twice as sharply you need 4x the computational power.

    If they removed the guard bands between transponders there is just enough room for 32 channels (31 + guide) in the 950-2150 MHz range, using 974 MHz for the guide channel as before. Before anyone suggests that's impossible, consider that Directv's Ka transponders are nominally 36 MHz wide, but have 20% roll off which means only 30 MHz of that is occupied by the actual signal. The data in the ISSCC presentation for Directv's 'test' DSWM chip showed they could have spaced the transponders significantly closer if they really wanted to. The reason they chose 51.03, exactly half of ASWM's 102.06, had to be for compatibility with receivers that didn't have a firmware upgrade to understand DSWM's new channel spacing (i.e. they could still use half the channels that fell on the same frequencies that ASWM uses)

    This SWM31 would abandon that backwards compatibility, but they probably aren't worried about the devices that would be incompatible without a firmware upgrade (D12, R16, H20) since they're no longer deployed in new installs.

    With a 36 MHz spacing, there would be one channel overlapping from ASWM / current DSWM / "new" DSWM at 1586 MHz, so if someone had a HR24 in a box for a couple years that didn't have the firmware that understands DSWM, it could still be plugged into a SWM31 and be able to get itself updated. Assuming the firmware in the receivers was programmed to ask for that channel last when talking to a SWM31 so it is free "just in case" it is needed by an out of date receiver.

    WORKS GREAT.......................
