    The International Bureau Policy Division also scanned the original narrative/ technical documents into pdf format and have added them to the respective LOA web links.

    Mind posting those links spear61 for all us interested in this important history, but who cannot navigate the FCC site very well? :)

    Again, thanks for all the hard work ...

    Guess Spear61 will have to update the footprint map for SKY Brazil's future KU-45W with DIRECTV's recent amendment to its application for it following Intelsat's protest of the original submission.

    HoTat2,

    Sorry for the slow response. Ku-45W, has just been updated with new maps. Where we previously had but two beam footprints, we now have four.

    As always, Thanks to spear61 for his dedication!

    I've never seen Hartford listed in the footprint maps for the local hd channels. Is one available?

    Unfortunately, we do not appear to have a footprint map specifically for Hartford. Given a little free time, I will endeavor to find which beam does cover Hartford.

    We have some heavy-duty pro's here at dbstalk who may weigh in with some guidance too!

    Yeah, thanks Gary and to spear61 for the update to KU-45W' coverage beams;

    Just one confusing issue Gary;

    In the Schedule S it list an additional vertically polarized "TXV" beam listed in section 7 of the 312 form titled "SPACE STATION ANTENNA BEAM CHARACTERISTICS" making for a total of 5 downlink transmit beams when counted with "T1H," "T2H." "T1V," and "T2V,"

    Yet in the following section 8 titled "ANTENNA BEAM DIAGRAMS," this TXV beam is not listed as a d/l transmit beam, but only the four T1 and T2 H/V beams listed above as I would have thought sec. 7 to read as well. :confused:

    I can find no mention in the narrative or anything further on in the Schedule S to account for this "TXV" beam outside the sec. 7 listing of it.

    Then strangely , the last link in the updated post #22 has this "TXV" mentioned in it when I would have expected it to say "T1V."

    Any light you or spear61 can shed on this?

    Again, many thanks for the work done so far as always. Its much appreciated here.

    HoTat2,

    A quick chat with spear61 this afternoon - he has no further insight to offer at this time. He or I will add posts if additional information becomes available.

    OK fine;

    But do you know if we should take the last link in post #22 as actually the beam for "T1V" (that is "Transmit 1, Vertically polarized") instead of this mysterious "TXV" (for "Transmit X, Vertically polarized") beam?

    spear61 is busy for these next few days, but will soon generate new beam maps for D5, based upon the most recent FCC filing. Should be interesting!

    Yep, interesting;

    Being on the west coast, I expect to see my 110 signal levels drop to zero at any point now as D5 (Tempo 1) is reoriented so it's beam footprint is moved further east to better cover PR.

    Question:

    Post 4 shows a beam footprint for RB-2. That was never built/launched, was it? I thought that was the application originally filed for BSS before the FCC's guidelines were complete, and Directv launched RB-2A with its four spots on D12 (post 8) as a sort of placeholder and for further testing beyond that provided by D11's "experimental BSS payload"?

    Maybe RB-2 will finally be launched on D15, assuming it ends up at 103, since it has a BSS payload identical to D14's?

    Post number 2 actually ... :)

    And yes post #2 appears to be the original 2006 filing for RB-2 (S2712), formally titled "BSS-103W" at that time.

    The later amendment ("AMD") and modification ("MOD") applications for RB-2 filed in 2008 and 2011 respectively to bring RB-2 more inline with the future FCC rulemaking and orders (R&O) as well as other modifications like only 18 CONUS transponders instead of 20 in the original filing, also do not contain any mention of the 24 transponder payloads and beams for the Mexico and L.A.

    Gary and Spear61 may want to look at this for any needed updates and/or corrections here.

    I wondered about the 18 transponders thing, since D14 (and D15, if it becomes RB-2) have 24 transponders, with transponders 19 and 20 switchable to 24 MHz operation so they can be used in the US. If the original filing listed 20 and it was amended to 18, I guess they must have decided they didn't need that extra 48 MHz for CONUS.

    Did anyone ever learn what the four spot beams coming from RB-2A on D12 are doing? Are they just being used for testing, or are there earth stations in the places they're aimed at (i.e. perhaps being used for internal needs like Ka on 101?)

    it's a classified info - you must work in certain DTV dept to know it

    Just an update to say that I have been able to call in an get my DTV locals changed about four times a year over the last 2 1/2 years. I use these google earth maps to plan out my changes and they have worked very well for me. So glad they are available here.

    My travels are more north/south which helps to minimize the number of times I have to call in and change. If I was racing back and forth across the country I would be calling in all the time and I doubt they would make that many changes for me.

    Bottom line, travel patterns permitting, you can work with DTV to change your locals from time to time and avoid the fee for DNS service.

    Hey Gary;

    Thanks for posting this update, but I'm still somewhat confused on the beam listings for IS30 here. As they should read (for the related downlinks above);

    CBCL - California Broadcast Center Left Circular (downlink).
    PRLD - Pan-Regional Left (Circular) Downlink
    PRRD - Pan-Regional Right (Circular) Downlink
    R1RD - Region 1 Right (Circular) Downlink
    R1LD - Region 1 Left (Circular) Downlink
    R2RD - Region 2 Right (Circular) Downlink
    R2LD - Region 2 Left (Circular) Downlink
    R3RD - Region 3 Right (Circular) Downlink
    R3LD - Region 3 Left (Circular) Downlink
    R4RD - Region 4 Right (Circular) Downlink
    R4LD - Region 4 Left (Circular) Downlink
    TCNL - Trans-Continental? Left (Circular Downlink)

    Located in files GXT26, GXT23, 24, GXT15-22, and GXT25, respectively at IS30's FCC menu of filings;

    http://licensing.fcc.gov/cgi-bin/ws.exe/prod/ib/forms/attachment_menu.hts?id_app_num=99684&acct=783256&id_form_num=15&filing_key=-249857
