    Instead of running the EIV, can you pull up the signal strength of each DSWM channel? If so, what does it show for 2 and 10 (and the rest)? Do you have a 3D2RBLNB to connect and run the LNB EIV on?

    Also, when you check the system, how does it know if you are at the LNB or the receiver? You tell it? What difference would it make where you are? I guess I don't understand what it's checking in this part. But regardless, very interesting about the difference in reported tuners based on location; it's definitely starting to look like a system (receiver) imposed limit.

    There was someone who tested one of the 3D2 LNBs a while back and they were 21 tuners, not 22.

    it would be nice of you if you would dig the thread and prev one (DSWIM 13 tuners), that would help you be on same plate with other posters ...
    perhaps the post would be helpful ...

    Did you ever do a similar test on the 3DR? I don't see any reason why it wouldn't be the same, but I don't know if anyone ever did like you did and packed a 3DR with 21 tuners all on different transponders and tried to add a 22nd.

    It is too bad there isn't a way to tell the SWM to share transponders, then when I eventually replace the H20s I could get rid of the amp, PI, splitters and switches and use a DSWM LNB. That would actually make sense for almost any use other than a large MDU. The odds of any individual residence or sports bar needing to tune more than 21 transponders are pretty much zero no matter how many TVs they have! But I won't hold my breath for this to ever be an option :)

    I'm pretty sure each SWiM channel monopolized after finished negotiation by each STB and wouldn't share with other; it would be huge mess, if one of sharing the channel STB would ask to tune to other tpn while other STB still need same as before

    I realize the SWM would have to keep track of what receivers have what channels and be able to reallocate them. If they wanted to they could make it work, but there's no way they'd go to that amount of effort when they have the legacy LNB + switches solution available. Like I said, I know it won't happen just wishful thinking :)

    As I posted, it used to be that way when the SWM8 first came out. Several of us tested and managed to get 13 or 14 tuners all running on the SWM8 as long as they didn't ask for more than 8 different transponders. I don't know when that changed.

    Thanks, that does kinda help...in making me think the 3DR can output 22 channels while the 3D2 can only output 21...

    But to your main point, I have tried to read every post in every thread regarding this topic, but when combined with keeping up with other DirecTV threads on different topics, it's easy to either miss some posts or honestly forget them.

    That does help though, especially when combined with the screenshot at the top of the page which really seems to indicate the 3DR can output 22 programming channels in addition to the one guide channel.

    5D2RB Followup.

    Ignored the warnings re 13 tuners.
    Loaded a bunch of boxes including an HR54 . Mostly vintage HR-20's.
    2 Tuners excluded for "4K" by HR54. Some H2* non DVRs.

    Didn't seem to matter order of recording.
    Using my trusty SAT/TPN/CH grid to confirm unique TPN for each channel recording, I can say that 18 different programs were recording without any hiccups. No error messages. Went back and forth over a hour or more and confirmed all recordings intact.

    I cannot evoke any Tuner limit given the 21 tuners, 18 recordable that I have available.
    End of my story
