    This is an update about what is happening with Ch 499 in my Guide. My earlier post a few days ago showed the Ch 499 Guide listing changing form B Band converter Test etc. to "To Be Announced" at 3 AM PDT today ( Aug 25)

    Link to earlier discussion:
    http://www.dbstalk.com/showpost.php?p=1062367&postcount=1367

    I checked this morning and the TBA on 499 had changed back to "B band converter test channel" , but for only 24 hours. The new "To Be Announced" just moved forward one day to Sunday Aug 26 at 3 AM PDT.

    Seems to me this Guide listing is being actively managed and is not just a simple Guide error. I am still expecting some sort of test message to appear here on 499 sometime "TBA" as they say. I will check to see if it changes again tomorrow .

    So that readers can distinguish one TLE from another, the third chunk of data on first line is the "epoch time" of the projection.

    The first two digits are the last two digits of the year (2007)

    The next three digits are the day of the year (August 25 = day 237)

    From the decimal point on is the fraction of a day relative to UTC/GMT/Zulu.

    Using oakwcj's recent post as an example:
    The epoch time is 07236.24078469

    Year = 2007
    Day = 236 (August 24th)
    Hour = 5:46:44 UTC

    Pardon the interruption ...

    Many recent posts moved to another thread for HD Anticipation -
    http://www.dbstalk.com/showthread.php?t=96029

    For the benefit of the people following the tech side of D10 please keep this thread on topic for where the satellite is and any signals received from that location. Discussion of what D10 will bring to D*'s service are better off in another thread.

    Thanks for your cooperation!

    It appears its moving back to the West now...maybe headed to final position, i hope.
    I guess its not moving West, or its a difference between mine and Lefty's programs again, mine had it at 102.5831 earlier but now its at 102.5827.

    As you can see on the spectrograms taken from D* triple LNBF, signal on tpns 103W KA-Hi 1650-2150 MHz doesn't changed yet:
    [midddle freq = 1750 MHz]

    But aren't we now looking for signals on Ka-lo, 250-750MHz? That is what should be coming from D10.

    Cheers,
    Tom

    I did check Ka-Lo [250-750 MHz] - there are a lot of odd/even tpns, but I found ( by blocking eyelets on the LNBF) it coming from 99W.

    Huh? What would be coming from 99 at those frequencies (to be used by D11)?

    Actually I don't remember how Ka-Hi/Lo related to the freq ranges. Has been posted ?

    Also if someone knows how to control BBC ? By default it doesn't convert 250-750 to 1650-2150 MHz.

    To do a 'sanity check' on which Ka feed scaler you are blocking (99 vrs. 103), take a look at your receiver signal levels w/o blocking (depending on your location you should have at least one reading on each Ka sat), then block the one that you 'know' your HD locals are on (the 'hot' one >90). Re-check the reading on the receiver. Should of course now be 0, and your HD locals are "searching for...."

    That will check which scaler/feehorn is which. You may have the geometry 'fuggered' out in reverse, and the signals you are seeing at 250-750 are from 103. At least, do the 'sanity check' to confirm you know the 'left from right'. :)

    Isn't that scaler 'cute'? Jeez, I knew that cellphone camera was good for something!

    The stack plan for Ka-hi/lo:
    Output IF Frequencies
    Ka-Lo: 250 - 750 MHz (right on top of OTA)
    Ku: 950 - 1450 MHz
    Ka-Hi: 1650 - 2150 MHz

    Stack Plan – 18V, 22khz (even transponders)
    Ka-Lo, 103°LHCP
    Ku, 110°/119°LHCP
    Ka-Hi, 103°LHCP

    Stack Plan – 14V, 22khz (odd transponders)
    Ka-Lo, 103°RHCP
    Ku, 119°RHCP
    Ka-Hi, 103°RHCP

    Stack Plan –18V, no tone (even transponders)
    Ka-Lo, 99°LHCP
    Ku, 101°LHCP
    Ka-Hi, 99°LHCP

    Stack Plan – 14V, no tone (odd transponders)
    Ka-Lo, 99°RHCP
    Ku, 101°RHCP
    Ka-Hi, 99°RHCP

    As for controlling BBC, I think but am not certain, that it responds to Diseqc controls, bursts of the 22khz tone.

    HTH,
    Tom

    Ah, I recall the table from WB68 brochure.

    Is there more info ? I'd like to know those tpn## and freqs for Lo/Hi ranges. Then measuring freq on spectrum anayzer I would be certain.

    What is the difference in parts of Ka 99W for the example:
    Stack Plan – 14V, no tone (odd transponders)
    Ka-Lo, 99°RHCP - which odd tpns ?
    Ku, 101°RHCP - we knows there are tpn1,3,5...31
    Ka-Hi, 99°RHCP - which odd tpns ?

    My guess is that TPs 1-8 are hi and 9-32 are lo. I know that the S1 TPs 62.5MHz wide right now.

    Cheers,
    Tom

    As you can see some of them on my spectrograms.
