    Actually, bonscott, if you look at the HD LiL by Launch Date list I've done, you'll see that the overwhelming majority of HD LiL launches have been on Wednesday, not Tuesday. In fact, I believe all the 2006 and 2007 launches have been on Wednesday.

    Thus, I'm predicting the HD channels will go live on September 5th or 12th.

    Was wondering since the sat is parked in the 102.6 area. Is it normal for the latitude to drift one way or the other as much as it does? Forgive my ignorance in this area please.

    The spacecraft has not been drifting randomly - it's been in very high-altitude, low-eccentricity orbits that are not quite circular. That results in the satellite seeming to oscillate east or west as viewed against a non-moving map or globe. In reality, the satellite is and has been revolving around the earth's center of mass while the earth's surface rotates beneath it the whole time. Now that it has finally reached a true GSO orbit, it will not move much at all from day to day, and will require only the tiniest of corrections periodically to maintain it's "slot" at around 102.6 W (bearing in mind that these are rounded off the decimal place - a tenth of a degree is approximately 45 miles at that altitude! But anyway, it will stay around 102.6 W until it's time to move to the final slot at 102.8 (or 102.775 if the change is approved), and that drift will take a couple days. We'll know when it starts when NORAD issues new orbital elements, indicating the orbit has changed.

    Change was approved. There was a prior posting on that.:)

    Thanks for the quick response lamelefty it seems like i learn a little with each post i read so i know you said it doesnt drift east or west again forgive my ignorance but what about north and south that is what i was talking about.

    I remember a REQUEST for the change, but do not remember the change being approved by the FCC? Can you indicate which post number that was? :(

    Also, on a slightly different subject, when I do a "re-install" of my satellite settings, I get a failure on Sat 99? :( Is this normal? And, will a 103b appear at sometime, or will we be required to "re-install" the satellites?

    Cheers,
    John

    Sat 99 currently only has spot beams for HD locals. Your locals will be on either 99 or 103, and the other will not show signal. Once D10 is live, everyone will get signal at 103. Once D11 slides up next to the Spaceway at 99, we will all get signal from that point as well.

    Have the opposite problem up here in MN - HD locals on 99, nothing on 103 for a couple more weeks.

    Edit: From the fine list over here it confirms your HD locals are on 103. You will have no signal on 99 until D11 lights up in early 2008.

    Movement north and south of the equator is caused by an orbit's inclination - the angle between the plane of the orbit (HS geometry sometimes IS useful after all :) ) and the equator. As the spacecraft moves along the path of its orbit, it will change position relative to the equator, north or south depending on where it is in its orbit. Ideally, a GSO has a zero inclination and a period that exactly matches the length of a day - in practice there are always errors and things that perturb or nudge the satellite slightly, including such things as solar pressure - the momentum caused by photons and charged particles from the solar wind impacting the spacecraft surface. Those giant solar wings have enough surface area to make a measurable difference. So too does the gravity of the moon and the sun. Every so often the spacecraft will make tiny corrections to the orbit, at which time NORAD will notice it with its tracking radars and telescopes and update the published TLEs.

    Did the Dog Whisperer get ahold of Harsh? He's been very, very quiet. I guess the beagle has been tamed.

    103 i get 7 transponders 98-57-88-96-66-3-45-all others 0-0- so forth

    must be locals

    My guess is the new satellites will fill up the N/As we're seeing today in the existing transponder charts.

    I have tried to find out the meaning of "a" and "b", so far no luck.

    Cheers,
    Tom

    It may be possible to get readings on 99(b) before local HD service is active.

    I am getting strong readings on 99(b), but do NOT yet receive any HD locals here yet. My DMA (125) is not scheduled to get them until D11 goes live.

    My transponders 1-8 on 99(b) read:
    0 97 0 97 0 0 N/A N/A

    My guess is that my dish is picking up the Seattle HD Locals that are listed in your link as on 99, but since I live in SE Washington in DMA 125 I am not eligible to receive them so they are switched off. My SD locals are on 119.

    I get all zeros (plus the N/As) on 103(a) but some DMAs might get a reading like I do on 99(b)if they are within the beam area but not eligible for the stations in that beam. Or is it possible I am due for a surprise and get all our HD locals early ( we have five OTA) ?

    FWIW, here in Cleveland, I'm getting the following on my HR20 (with BBCs installed):

    7 total at 103a:
    1-8: 95 0 94 67 95 59 NA NA
    17: 0 NA ...

    6 total at 99b:
    1-8: 14 69 59 79 69 0 NA NA

    Yes, I get readings on 102 for every transponder (that is not NA) but one (channel 499 transponder), and I still don't have SD locals from DirecTV.

    I get no signals whatsoever from 99.

    Ken what does the numbers under DMA mean on the chart?
    I'm sure everyone else in this thread knows that, but remember I'm the dumb one in the group :blush:

    Being out of the loop for so long I need some help understanding what my signal strength screens mean. Currently I have 101, 110, 119, 99a and 103a. Where can I find out what channels I am receiving from these locations? Also the 99a location reception is usually between 76-80. Any ideas why this is so low, besides possibly the dish needing to be adjusted.

    Thanks

    101 contains most SD channels on D*, including SD locals
    110 contains HBO, Showtime, ESPN, Universal, TNT, NGC, & HDNet Movies, all in HD (MPEG-2)
    119 contains ESPN2, Discovery-HD, and HDNet, all in HD (MPEG-2) plus a bunch of SD locals

    99 & 103 mostly contain the locals in HD (MPEG-4). Looks like you might be seeing the spot beam for Sacramento on 99.

    If some of this data is old, I expect someone here can straighten me out.
