    Well Sixto previously added the LNB test channels on D10 and D11, so I just suggested in that case he may as well go on and add the missing two on D12 for 103A odd and even as well.

    And while I agree its a minor point as I stated P. Smith, I don't think its fair to say there's "no point" at all, unless your saying Sixto shouldn't have bothered to list any of the test channels to begin with.

    We can't name the very low data stream as a channel; these services never produce anything but short message.

    Well that's fine P. Smith, but I think you really need to address that to Sixto and not me. It was his idea to list the LNB test channels on his maps to begin with, not mine.

    In fact after I reminded him about the ones for D12, he even said that he thought he added those test channels on D12's map, but had "slacked off at the end" in post #177.

    Let's move on.

    Yes, I will be adding those two to the map, just like I've always listed the others for D10 and D11.

    Yes, they're very low bandwidth. We know that. That's why I noted them a little different with dashes in the front. It's no big deal.

    Edit: Added.

    [IMO] I strongly opposed to count the services with short string test message as a channel, especially in tables of counting real channels[/IMO]

    Hear ya P. When I originally added them it was because they were full time and I figured that it might be a good thing to show how they do the LNB check. I could go either way, but will leave them for now, but opinion understood.

    Maybe a new section, "Other Non-Channel Bandwidth Usage"?

    I'd like your way of thinking :D ... really, there are many other bitstreams on each transponder: system tables, APG, MPG (yes, old, legacy stream is there, for old 'ancient' IRDs like Sony), authorizations, LiLs info, etc

    Been giving this more thought, you've convinced me, removed the LNB tester channels, it probably would confuse more then it would help, especially since I don't list the part-time channels. Have made note in the legend.

    The commenting here is good, always open to all perspectives.

    Just wondering if people prefer it sorted in channel number (lowest to highest) for each transponder like it is now, or if they'd prefer it sorted by program id (lowest to highest) so at a glance you could see which TP's have 6 HD's or 5 HD's on them by the presence of 1060 or 1050 as the bottom line item?

    When I mapped cable QAM I always did it in Frequency , PID order lowest to highest.. (small example from my cable operator)
    [table]EIA CH 85 - 591 MHz
    -PID - MAP - NAME - RES
    -5501 - 21 - TWC -720x480i
    -5502 - 24 - EDAC024 - 720x480i
    -5503 - 19 - LOOR019 - 704x480i
    -5505 - 16 - WPMT - 704x480i
    -5506 - 09 - WPPX - 704x480i
    [/table]
    and so forth.

    Yep, good question, I've listed them both ways over the years. By VPID would actually make it easier to keep the table maintained, because every time something changes I need to resort the table. Will see what others think.

    Well I'll start with my opinion.

    I prefer PID because at a glance you can see the numbers without counting each line to determine how loaded a transponder is.

    The channels are distributed amongst transponders and satellites in a random fashion anyway so even if I am looking for a particular channel I do a CTRL+F and search by name or number in my browser.

    I'm in favor of gong by VPID if it will make things easier for you. I don't know how much work your reports take and such, but considering all you, gct, Doctor J and everyone else does for our benefit, I'm all for making it less labor intensive.

    Everything is automated except that table, which I guess I could automate as well. Right now that table is manual, and I need to change it all around every time a channel changes, will think this through.

    After reading comments to some 'hybrid' networks ...
    I see it could be Verification Channels, like 9043 *CEVC.

    Note: Although I notice that Ku band CONUS transponder 24 at 119 (D7S) is using 8-PSK for Spanish MPEG-4 MEGA HD (ch. 405) and TFTw HD (ch. 408).

    http://www.lyngsat.com/DirecTV-7S.html

    Assuming the LyngSat entry is accurate of course ... :)

    EDIT: Then again looking at the formula for satellite data throughput I posted back in January.

    http://www.dbstalk.com/attachment.php?attachmentid=28211&d=1327482283

    I suppose they really had to go to an 8-PSK modulation level to achieve something close (~37 mb/s) to the typical ~39 mb/s data rate for Ka band CONUS HD programs mentioned earlier in this thread.

    With a 24 Mhz wide transponder on Ku band, they only had the SD standard SR of 20,000 KiloSym./sec. to work with instead of the normal 30,000 KS/sec. on Ka band for HD afforded to them by the larger 36 Mhz wide transponders employed there.

    From Sixto posted on locked thread:

    Sixto, shouldn't the selected mix channel 9702 be on D10 Tp. 14 based on previous postings?

    Is 9701 through 9705 all US Open content? Are we sure because they are labeled *DTV.

    Those *DTV channels seem to be what are now test channels which were formally the US Open "placeholders" in Sixto's previous post #1466 on the locked parent thread.

    http://www.dbstalk.com/showthread.php?p=3033684#post3033684

    That's why I questioned if D10 transponder "10" was accurate for channel 9702 and shouldn't it be Tp. 14.

    My download this AM shows 9702 as a NET 15 listing but "Redirected" from NET 10.
    NET 10 is 99c (D-11)
    NET 15 is 103ca/cb (D-10/12)
    I don't know how or why this is, it just is.
    D-12 TPN 10 is the 2nd Conus Transponder and would correlate with TPN #2 listed for others.
    The PIDs are sequential 1010,1020,1030,1040??
