    VOS -- thanks much -- I had a "senior moment" with the cable -- I meant RG6 vice CAT6. So you are say in summary that I can go directly from the sat dish cable into the house cable and then straight into the receiver? I can bypass all the SWiM equipment since all I have is one receiver?

    You still will need the power inserter, BUT you do NOT need/want any splitters.
    Also, due to the way the signals are on the cable from the dish, you WILL NOT be able to combine your over the air signals on the same coax that feeds the reciever.

    You MUST use a seperate cable.

    While it may be better to use two coax, "If you're not" using the DECA networking, the SWiM frees up the OTA band so they can be combined, though it isn't supported by DirecTV.
    The SWiM uses a 2.3 MHz FSK signal for communication, but the next frequency is 974 MHz, leaving the whole OTA band unused.

    So you don't need the splitter, and can combine your OTA onto the coax, and then split/diplex the OTA back out near the receiver.
    Two of these should take care of it: http://www.solidsignal.com/pview.as...e-/-Off-Air-Diplexer-Power-Passing-(STD-9501)

    Again --- thanks much. I have the diplexers on hand. I will give it a shot to see what happens.

    Not all diplexers are the same, so your results may vary.

    Tried it today with some failure and success. First tried it by bypassing the SWiM splitter at the demarc point and eliminated the SWiM power unit at the receiver. No luck and no signal from the dish. Success came by reconnecting the power unit at the receiver. All the splitters and diplexers work great for the OTA. Thanks again.

    I was going to post this in the thread that describes the setup for more than 16 tuners but since you mentioned this issue here I will ask my question here.

    It looks like the preferred setup for more than 16 tuners is to split the four cables from the dish into the inputs of two SWM 16s. Postings in other locations say that the splitters between the dish and the SWMs should have both ports with power passing. Every 2 way 2 port power passing high frequency splitter I see only goes down to 5-10 MHz. The only exception is the Sonora HRVS2, which is rated to 2 MHz.

    Since this communication signal is at 2.3 MHz, it would seem to me that having a splitter rated to 2 MHz is advisable unless these signals are so strong the 5 or 10 MHz rated splitters pass an acceptable signal. Yet, almost all of these are not rated that low unless they are single port power passing.

    Is 2 port power passing necessary and should the splitter be rated as low as 2 MHz?

    I will add that while the Solid Signal white paper on the setup for more than 16 tuners uses splitters with 2 port power passing (rated to 5 MHz), the Sonora page for their polarity locker includes this statement that seems to confuse the power passing issue:

    RELATED CONSIDERATIONS
    Splitting the 4SATPL-T output to two switches requires DBS splitters with DC passing to only one port or diode steered splitters. Models HFS-2, HRS-2, HRvS2P or HFS-2D may be used.


    Thus my confusion. Any guidance or clarification on these issues would be appreciated.

    Sonora likes to hype their products and the skywalkers are "diode steered".

    Your knowledge in these matters is astounding. Thanks.

    Just for completeness sake, the 22 KHz tone gets passed through these splitters, correct? Even though they are rated far higher?

    Yes, it's so low that it passes on the DC circuit.

    The 21 volt PI is rated @ 25.2 Watts

    The older 29 volt PI [with cooling vents/slots] is rated @ 36 Watts

    The newer 29 volt PI [no vents/slots, so looks like the 21 volt PI] is rated @ 40.6 Watts

    The 21 volt PI should NOT be used on the SWiM-16.

    veryoldschool,

    Is there an HR34 specific forum?

    Im upgrading from Slimline5 , (i do not have SWM), whole house is wired for cat5e, and I am networked on. Unique to the situation, I have two 16 port multiswitches cascaded to each other. specifically to gain 10 tuner ports behind theater area wall. 2 of those lines piggy out and back to master bedroom. I have a decent amount of keystone jacks.

    I want to make sure mastech has everything they need to complete this install without issues. Equipment / DVRs as follows:

    5 HR20s
    1 HR24

    (4 are in one media room) , 1 in bedroom, 1 in room over garage

    Want to end up with

    HR34 , and HR24 in media room, 1 HR20 bedroom, 1 HR20 Master


    My thoughts this morning were to : reduce bill (unemployed for a while now)
    reduce heat dissipation in media wall. 3 HR20s, and HR24, little toasty. Been ok for about 5-6 years now. I will be dropping at least one HR20 for time being.

    Ive been with direct for over 12-13 years or so.

    Ended up with 1 cnote for HR34, and a 50 install fee,

    Why am i paying for professional installation, ??? Best I could get was 15 credit on install, free hd for 2 years again, and 5 for 12 months or something.

    Plan was to dump three HR20s, and pick up HR34, reap benefits of cooler and faster operation, reduce bill 12 dollars (box fees) and reduce a little on the electric bill, and reduce heat.

    I guess I will have it installed them speak to directv about installation charge. Doesnt seem nice after 12+ years,

    I know its a lot in one post but hey, Ive got a big story to tell!!


    Future possibilities, Dump 2 more HR20s, and have RVU boxes with "fewer" additional receiver fees. Directv has a great chance to gain much praise from these technology conveniences.

    I'm sure VOS will chime in with any additional insightful info. :)

    But for now ...

    For firmware related issues yes. http://www.dbstalk.com/showthread.php?t=205798

    Everything else on the HR34 is sort of scattered around among various threads I'm afraid.

    Likely because you are upgrading from legacy to SWM plus WHDVR. New SWiM-16 multi-switch needed, DECA equipment, CCK, splitters, etc. plus labor involved. It adds up.

    When my HR34 was installed the fee was waived because I already had all this infrastructure and it was simply a matter of swapping out a current receiver (an HR22) for it.

    RVU clients have the same monthly pricing structure as additional receivers, at least for the first three of them. So you won't save anything on fees and will actually lose two tuners. And the two tuners that remain must be borrowed from the HR34. 1 for each RVU client when in use viewing live TV.

    So rvus have 6 fee as well for additional reciever? As far as tuner usage for live tv... Ok with that just two in house. In fact we run hdmi over cat5 for guests bedrooms. Saves money. To pull signal from unused room. Yes we do have legacy switches. But already have gigabit networking to all rooms.. Sorry no decade cck needed. That's what I want to make sure not paying for. I've payed 3 sine mrv was went mainstream.

    The HR34 requires a full rewiring.
    The coax drops from the dish stay.
    From there you need a SWiM-16.
    One leg to media room where it feeds the HR34 & HR24.
    Other leg feeds the bedroom & master, where DECAs are needed on each.
    Internet access comes with a CCK.

    This is $300-400 in hardware + labor, not counting the HR34.

    Yes, for RVU clients its called the "Home Media Center" fee, currently $6.00 a month per client (for the first three its thought).

    Though incorrectly applied to someone's account in this case, its nevertheless discussed in a thread here for example:

    http://www.dbstalk.com/showthread.php?t=206434

    The DIRECTV techs. are still trained to install a CCK with the HR34 anyhow and may insist on it, though you may remove it afterwards.

    Also, they will not deal with ethernet for MRV only DECA coax networking.

    You will have to set up ethernet networking for the boxes on your own afterwards.
