    These channels are now gone from directv usa and already testing on dishnet 118,

    Counting separate PIDs for the tp21 [TID 188]: it is 9 separate channels there. No mirrors. If it will cover little south then we could measure bit-rate or each channel/PID ...

    Is it a Record for Ka tpns?
    Or DTV will follow a competitor and will compress LiL more and more. For now 103 tp 12 and 13 (CONUS) running 7 channels too. Also many spot-beams at 99W and 103W - just sort by a column VPID to discover the numbers.

    Interesting tidbit: PID 1091h is assigned and used for Ka tpn's Test Messages (ch 95xx), so it was projected up to 8 channels per Ka transponder from beginning (PIDs 1010h...1080h). As to tweaking FW of statmuxers last months, I didn't buy it from beginning that count must be 6 and no more. Perhaps the manufacturer didn't fulfill original DTV's specs in FW versions up to last months.

    Well, thanks for giving it a shot. Road trip? :lol:

    They must be using a different modulation on some spot beams compared to the CONUS tpns in order to increase the bit rate for all those LiLs, you think?

    It still has some bugs (weird things showing up or not displaying correctly) to work on, as well as a few updates regarding National Ownership and perhaps the Dish Network information, BUT....

    ... the transponder information is interesting.

    From an OTA perspective, KUNP (Univision Portland) is a 4:3 channel. I can't tell whether it is SD or HD as I'm using a Slingbox Solo.

    Wow. If Directv has found a way to ratchet up to 8 or 9 HD/MPEG4 channels per TPN, that just really kicked the barn door wide open. The opportunities now become really wild.

    For the LatinAm folks, a development like this could be a real jump-start for all of the LatinAm market, even before the two new Latin Sats are up and operational.

    Thanks 'Go Beavs' !!

    Where you get this ? Main page of the site is telling about some game ...
    I would question that page's creator for a sources of that DTV LiL info.
    I wouldn't surprise if we will get link back to gct's threads here.

    Ahh, thanks, QPSK 4/5 47 Mbps. 47/9=~5.2 Mbps per channel.

    Looks like CONUS a while back was QPSK 2/3 39 Mbps. 39/6=6.5 Mbps per channel.

    Wow, I really don't see a PQ difference. Maybe I need to look harder. :)

    PQ not withstanding, the reduced FEC may increase your rain fade.

    Unless the reduced FEC is compensated if not more by the higher PFD of a spotbeam.

    What's stopping them from going QPSK 4/5 47 on CONUS feeds if these LiL's are testing OK? Rain Fade considerations?

    I don't think I could trust 8PSK on Ka without a poor rain fade experience, but it would be worth seeing test data and signal measurements. I say, DirecTV be adventurous and put HD channels people really don't care about in a 9:1 mux using 8PSK (stuff like CSPAN's, Shopping, Religious, etc..) just to see what happens.

    I'm pretty sure they have monitoring stations all over US.

    Yeah, switching to 8PSK would go from typical 39 Mbps to 52 Mbps is big step - 33% increase.

    There are a few tpns what already using it - do we have our observers in that DMAs to report here about good and bad outcomes ?

    Nope, sorry not in my market. I thought a bigger market like Philly which has a lot of stations may, but that's not the case.

    These TIDs/tpns seems to me temporary doesn't have 7th in a middle of typical range or more - check it by VPID values (for 147 - 1060 missed, for 156 - 1010 and for 157 - 1010/1020/1030 ).

    Do you check what modulation/FEC on these ?
