    It would cost a bit to have the two FSK signals be able to pass data/requests between the two and it just seems this feature wouldn't warrant it with the CCK/DECA being the focus.

    It'd be nice if IRDs shared callbacks over DECA. The do share ethernet reporting, but AFAIR each leg needs it's own phone connection.

    I've read a lot and searched a lot on this board, but I am still confused. I currently have the slimline 5lnb with 4 lines to a swm16. From that I'm running 4 hd dvr receivers.

    Question is I need to replace the lnb due to signal issues. Do I have to get another slim 5 lnb for the 4 lines? Or do I get a 3 or 5 swm lnb? Do those work with the swm16? What are the advantages/disadvantages to using the 4 lines versus the one line from the swm lnb? I've read that you get a stronger signal from the 3swm lnb. Is that true? Thanks for the help.

    You can't cascade SWiM, so if you want to keep your SWiM-16, you must keep the four coax legacy LNB. It can be either the SL5 or SL3.
    Not sure where you read "you get a stronger signal from the 3swm lnb", but :nono:

    I need help with a self install for connecting an HR34 and a HR20 to a SWM8. Does it make a difference which HR is connected to SWM1/PWR port?

    No difference. Enjoy the five tuners in the HR34!

    I updated to a HD DVR model 22-100. I ordered a single wire swm lnb and 8 way splitter. I unhooked everything and hooked up the single wire went in the splitter to the power inverter and now have no signal. I have a slimline 5 dish. Any idea where I went wrong. I looked thru some diagrams and it looks like its hooked up right. I have no signal on either tuner for any of the satellites. Lost...:confused:

    Is your power inserter before or after the splitter? If after, make sure you use the RED port for the receiver with the power inserter.

    Did you go into the menu and rerun satellite setup? Slimline 5 and SWM setting?

    Did you remove the B Band converters? They need to be removed for SWM.

    If you swapped out a SL5 for the SWM, are you sure you used the same coax outside, as the one you hooked the splitter to inside?

    This may be more than you have, but should show how it should be connected:

    Wednesday DirecTV upgraded my system by adding a HR34 , a SWM16 (replacing a Zenwill 16 Port multiswitch) and a 3LNB dish with4 coax's down to the SWM16 (replacing a 5LNB dish).

    The DirecTV installer said that this in only the second HR34 he had installed he need to contact other techs for help.

    Questions:

    -Was it necessary or desirable to install the 3LNB in lieu of the 5LNB?

    -The HR34 is connected to the SWM16 via output port one and seems to be working fine. My existing HR21 and HR23 are connected to the legacy ports 1 thru 4 of the SWM16. Is there a reason that the legacy ports were used for the HR21 and HR23 rather than output port two of the SWM16 with a splitter?

    Thanks to all in advance and regards,

    jcthomas

    If your SD locals don't come off the 119 SAT, there isn't a big need to have an SL5. There may be a few music channels still there, but not much.

    Your HR21 & HR23 SHOULD NOT HAVE BEEN connected to the legacy ports.
    The SWiM-16 has two outputs, so one for the HR34, and the other for the HR21 & 23, and adding DECAs to these two, would mean they would have access to all the recordings if you have MRV/whole home DVR service.
    If you don't have this service, this "may have" been why they were connected to the legacy ports, as the SWiM output would require them to have a bandstop filters.

    Thank you VOS.

    If I move HR23 and 21 to the SWM16 output two with a green SWM 4 splitter and utilize diplexers in lieu of the band stop filters (diplexers I have but will have to order BSF's) would this be a temporary fix?

    The installer activated MRV but did not install DECA's for the HR23 and HR21. So until I can get the DECA's, can I use hard wired ethernet via my router for MRV on the HR34, 23, and 21?


    thank you and regards,

    You'll need to remove the BBCs on the HR21, and mount the diplexers where they'll be "splitting out" the DECA signal from the HR34, and I'd use a terminator on the OTA ports.
    "But" yes this looks like a "temp fix" that will work.
    DECAs will do what a BSF does, so this is use one or the other, but not both on the same receiver.

    Thank you VOS.

    So, now off to fix the setup.

    I've got an chimney mounted legacy Triple LNB dish (101,110 & 119) that's getting ready for a HR34 upgrade I've mounted a new Slimline jpole and have leveled it with dual braces. Yes, I have a good LOS. I will be using a SL5 LNB and a SWM8. I will be retaining a few of my old SD DTivos as well... obviously this is why I've chosen this dish/multiswitch setup.

    My question is when the dish is aligned is it done with the SWM8 attached (all 4 coax)? I would prefer it that way if possible because I will be mounting the SWM8 in the attic.

    From what I have read here and after speaking to a local satellite co they indicated that they remove the LNB and temporarily installing a coax for aligning then after the alignment was done they remove the LNB so the other coaxs (4) can be reattached BUT I would rather the LNB NOT removed AFTER the alignment process has been completed. It seems to me that to retain the best signal strengths especially for the KA band sats that removing and reinstalling the LNB simply allows for too high of a chance of losing the best signal. (Especially since I will be paying for it, why remove it after aligning it).

    I have also read numerous posts indicating that other individuals have done similar things like simply changing out the LNB without realignment and have gotten away with it. Maybe they were just lucky or just maybe we haven't read about the "rainfade" issues later on due to the signal being a little weaker after the R&R.

    Any thoughts about this would be greatly appreciated.

    I tend to think your concerns are a bit misplaced.
    The Slimline LNB can be removed and replaced without measurable changes.
    Having the dish aligned well and secured well, is much more of a factor than whether the LNB has been removed and replaced.

    What is your plan for including "a few SD TiVos"? The SWM8 will only support one.

    By itself you are correct, however by using some additional components I will be able to take 2 of the 3 legacy outputs off of the SWM8 then "stack" the signals then amplify that signal then distribute that signal to multiple rooms with my old legacy SD DTivos (while maintaining the use of the dual tuners on each). By doing it this way I can still have up to the 8 SWM tuners while providing my needs for my existing old equipment. I could also swap a SWM16 for the 8 in the future "if" I were to need more than 8 SWM tuners.

    I've attached a link below for a device that allows this to happen, note that this device "stacks" the 2 101 signals and by using "destackers" @ the Tivos I get the use of the dual tuners even though a single coax was used to distribute to each room.
