    Don't buy it. Even if they begin D10's move to 102.775 W today, it will take about 2 - 3 days to get it where they want it. Then probably a day or two of testing, and all the sudden it's no longer the weekend.

    Unless the newest TLE shows D10 positively BOOKING it to the new slot, I don't buy it. But I'd be VERY happy to be proven wrong. :D

    May have been covered before.

    Could D10 transmit national beams while moving. I though it was already in a window that our dished could receive signals from it.

    I do not think they would do that, but just asking as a technical matter, could they do that.

    Yes, but they don't have a license to transmit from anywhere aside from 102.775, so legally they can't.

    Looks like Dish stole some "HD Thunder" from D* with this announcement:
    "...Dish launches History HD..."

    Come on D*, lets hear you ROAR!!! Park that Bird at 102.7 and git 'er done!

    Before D10 was ever launched wouldn't Boeing, DirecTv engineers, and the FCC have not done a whole lot of engineering studies that showed the 102.8 location doable? Only after D10 was launched and in orbit did DirecTv ask for a change of location to 102.775 to avoid a possible "collision" with other satellites. While we were all happy that they were requesting to move D10 early, I'm starting to think we should have been concerned there is at least a minor malfunction which limits its ability to maneuver and that could be why the change to 102.775 was requested. If that is not the case, then the original engineers on the project must have made errors in choosing a location that didn't work or at least wasn't totally safe.

    They are just doing it to say they were their first. I'm sure some of their channels will suffer PQ. Although the new channels may look fine, I am sure they will be stealing from other channels. It is Charlie being Charlie. If he had the room for them, why did he wait this long?

    I tend to discount the theory that there's a problem with the satellite that a difference of 11 or 12 miles makes any difference at all. I suspect it might be something as obscure as making sure one sat doesn't cause as much visible solar flash off its PV arrays at certain times of day which might dazzle the optical star trackers on the other sats nearby . . . a few miles' difference could prevent that entirely and it's not the usual kind of thing that a satellite designer might think about - engineers are used to thinking THEIR problems are the ONLY problems and that whatever they work on exists in a vacuum (no pun intended). And D10/11/12 have really BIG solar wings, which might make any kind of problem worse, if that's it at all.

    Anyway, that's just a guess - it could be ANYTHING obscure that no one thought of until the last minute.

    All good points. Perosnally, my money's on D* for this coming weekend...coincides with official NFL regular season kickoff and new season premiere of other network shows, and lots of new HiDef flat panel tvs on sale everywhere. So as I said before..." com'n D*, git 'er done!"

    IF D* were holding out until a good time for maximum publicity, I would agree that this weekend would be as good as any. However, I don't think D* is delaying a release at all, in fact every indication is that D* will flip the switch as soon as possible.

    As soon as possible is looking like next week, which happens to coincide with the majority of credible rumors including the anouncement to TVPredictions.com of having the first wave of HD by Sept. 16th.

    I of course don't have any information that hasn't been posted here, but since I am a betting man, I would place the over/under on Sept. 14th.

    Any takers?

    The 14th +/- 2 is a pretty safe bet, based on what's been said.

    So it could be an issue of how it would affect Spaceway 1, and have nothing to do with D*10's operation.

    Since we are all waiting for reasons to be cheerful, I thought I would make the following contribution. My ATSC broadcast of ABC on 6-1, 6-2 and 6-3 now say searching for signal on the off air tuner. The broadcasts are from Philadelphia on RF channel 64. I see this as a positive thing, because I have not yet physically separated my off air and my satellite cabling. Everything is still combined via a Terk BMS-58 and that means my OTA channels will be affected or wiped out as soon as D10 kicks in for real. I plan to add a second Terk BMS-58, which I already have in my junk room. I haven't done so yet, because I am using the off air conflict as a way of knowing when the D10 broadcasts have started for real. I am presuming off course, that some sort of test is under way from D10 and that channel 64 is being used as an IF from the LNB to the reciver via the Terk BMS-58. I like to leave things to the last minute! Is there anyone else whose off-air service via RF channel 64 is presently affected?

    Check your theory, disconnect the sat line and see if your ota comes back, if so maybe you are on to something.

    I hope D10 is alright :angel: But I love your quote :heart: I may make some people mad, but there should be no need to press 1 for English in the U.S. :grrr:

    If you read D* original letter requesting the move here...

    http://fjallfoss.fcc.gov/servlet/ib.page.FetchAttachment?attachment_key=-131920

    they state...

    By moving DIRECTV 10 slightly to the East and
    SPACEWAY 1 slightly to the West, DIRECTV will ensure that the station keeping volume
    of these satellites will not overlap with each other or with any other space station operating in
    the vicinity, including the AMC-1 satellite operating at the nominal 103° W.L. orbital location. This proposal will therefore advance the Commission’s goal of decreasing the risk
    of in-orbit collision between space stations and also enhance the efficiency with which
    orbital resources are used.


    The thing that jumped out at me was the last sentence about "in-orbit collisions". Has anyone out there heard of this happening?

    And if I read this original application here...

    http://fjallfoss.fcc.gov/cgi-bin/ws...=V_SITE_ANTENNA_FREQ.file_numberC/File+Number

    the "Action Taken PN Date" is still listed as "None" [I assume PN is Public Notice]

    Does any of this about the public notice raise any concerns? Just wondering.

    ABC in Philly have just made a liar out of me, because their three channels on 64 have returned. I suppose whatever test was running, has finished. Temparamental business, this. I have no further excitement to report.

    Curious why you think so. Sure, posting this in the tech thread would be bad form, but you don't think his post was appropriate for the anticipation thread?? It seem the exact right place for this kind of thing, and why it was split-off in the first place.
