    Hello,

    Can someone tell me what the directv C61K-700 genie client uses for frequency range over coax? I am trying to find out if it uses the whone 2 - 2450mhz or does it use a specific range because it actually connects to the genie 2 server i have? I am thinking it uses moca to stream the video to the client but i want to be sure because i need to run it through a ground loop isolator and they only work 5 - 1000 but i did find one that claims 5 - 2400mhz which may do the trick. If the genie client only uses a certain frequency i may have found my solution. The second option that would work is running the coax through an APC J10 AV Power conditioner where it says "satellite" for coax protection that also removed my ground loop but i cant seem to find any specs on what that coax connection allows through it for frequency range.

    So would this document cover that range http://www.mocalliance.org/MoCA2/sp...and_2.5_Device_RF_Characteristics-160808d.pdf

    If i have a ground isolator that does 5 - 2400 that should cover it i would suppose and i guess there is no DC power on the client either since the genie 2 server is doing that i would suppose ?

    So uou know specifically which range in that document there are quite a few. I just want to make sure my ground isolator doesn’t cause issues

    Yes, as P. Smith said ...

    The C61K client uses the MoCA 2.0 standard (not 2.0 "bonded"), but specifically the "E Band" to communicate with the Genie 2 server over coax.

    So operates between 400-700 MHz ..

    This is misleading and doesn't answer the question. Modern MoCA is 2.0, not v2 and covers a lot of territory from 400MHz to 1.5GHz.

    Are you sure the Genie 2 isn't using bonding?

    DECA has always been in the E band but it sounds like they've found more bandwidth.

    I've never seen anything more than "MoCA 2.0" with no mention of bonding for the Genie 2's internal adapter, nor any of it's compatible ancillary equipment such as the new "Giga DECA" adapters and WVB gen. 2.

    Oh, and the MoCA 2.0 bands actually span various frequency ranges from about 400-1700 MHz. Not 400-1500 MHz ....

    you are picky for other, but making factual errors every time

    My bad. I was using outdated information from Wikipedia that didn't include the D8a-D10a bands.

    Back to the TS's question, they should NOT be using any "filter" or "conditioner" on the satellite coax. It will impart insertion loss at least which will diminish both IF and DECA transmission.

    It uses the MoCA E band, between 475 and 625 MHz. And I'm pretty sure it is using MoCA 1.1, not MoCA 2.0. Possibly it uses MoCA 2.0 if you have an HS17, but the HR54 does not support MoCA 2.0.

    The HS17 will use 2.0 with any of the C61 devices K or no K

    What’s IF? Also what’s wrong with using a ground isolator? Isolation Transformer / Ground Loop Isolator https://www.amazon.com/dp/B00B2HFE2O/ref=cm_sw_r_cp_api_glc_fabc_8PobGbGPVW93Z

    I have an issue directv nor anyone else can fix. I have an audio system and the ground hum is bad we have exhausted everything possible to eliminate the problem but no luck just look at my posts here at this point i don’t have much choice. Trust me i know it’s no good to put anything inline with the satellite components but i was hoping if it’s just a client i can get lucky with this since the HS17 does all the work with the satellite LNB and not the client

    IF had a range 250-2150 MHz

    Again, the MoCA "E band", which under ver. 2.0 of the standard may operate on any one of nine overlapping 100 MHz wide channels between a total frequency span of 400-700 MHz.

    IF is the acronym for intermediate frequency. DIRECTV signals come down at relatively high frequencies (>12GHz) but are converted to intermediate frequencies (~1.1GHz) by the LNB.
    Are you sure that the satellite components are the cause of the hum?

    Is the hum 60Hz or some other frequency?

    When hassling with XLR cables (and they can be a real hassle), the astute audio troubleshooter will first try lifting the grounds.

    I don't know how many clients you have or if your Genie 2 is connected via wired Ethernet, but you might try something like this: C61k Mini to Ethernet via DECA?

    see post#13;
    adding to that usual three sat IF ranges: 250-750, 950-1450 and 1650-2150 MHz

    and again misleading :(
