    I made that mistake before...

    I meant fifth xD

    Yeah ...

    After some thought on the way channels are appearing on DLA-1, I wonder if its something to the effect of Network 3 or Sur is xpndrs 41-52 occupying the new Ku-lo band between 10.950-11.2 GHz and xpndrs 53-64 on the Ku-hi band between 11.7-11.95 GHz

    These two 12 xpndr groups (for a total of 24) is then in some way apportioned over two regional downlink beams labeled numbers 3 and 4 boresighted on southern portions of S.A.

    Norte or Network 4 seems to be reversed with its higher number of 12 xpndrs, 77-88 converted down from their uplink to the Ku-lo band of 10.950-11.2 GHz. And the lower 12 xpndr numbers 65-76 are on the Ku-hi band between 11.7-11.95 Ghz.

    And these two 12 xpndr groups (or 24 in total) are distributed over regional beams 1 and 2 aimed at northern portions of S.A. and parts of the Caribbean near adjacent to the continent.

    And to add to this;

    If my assumptions are correct here, then based on the listings of active xpndrs with programming in the latest release of the LA TPN maps, the new Ku low band (10.950-11.2 GHz) available to Sur and Norte are not in use yet. Nor do there appear to be any channels in testing yet on those xpndrs (41-52 for Sur, 77-88 for Norte) under the hybrid tab.

    UPDATE:

    After being very gratefully provided more definitive imformation on this. I find my speculations posted earlier here about DLA-1's regional xpndrs to be accurate.

    Xpndrs 53-64 of beams Sur and 65-76 of beams Norte downlink within the conventional Ku band of 11.7-11.95 GHz.

    And while unused at this rime, xpndrs 41-52 of Sur and 77-88 of Norte downlink in the new (for DLA) extended Ku band range of 10.950-11.2 GHz.

    "the conventional US Ku band of 11.7-11.95 GHz" - in whole world useable Ku band is 10.7-12.75 GHz ;)

    Yeah, but then it's very contextually dependent when speaking of band names which leads to confusion at times.

    Just like while yours may refer to the entire downlink Ku band. It's frequently divided into the "extended" Ku band usually from 10.7-11.7 GHz. The very popular "standard" Ku band from 11.7-12.2 GHz. And then the BSS or broadcast portion of the Ku band from 12.2-12.7 (or sometimes 12.75) GHz. All three portions many times loosely referred to simply as the "Ku band."

    Then in the context of the new DLA LNBF, the downlink from 10.95-11.2 GHz is considered the Ku-lo band and the range from 11.450-12.2 GHz the Ku-hi band.

    As I said, very contextually based and confusing.

    I've been retired for a while, but when I was working in the aerospace industry, we always referred to the frequencies between 8.2 and 12.4 GHz as X band. Ku band was from 12.4-18.0, K band from 18.0-26.0 and Ka band from 26 to 40 GHz. These were based on the bandwidth of various waveguide sizes, but I guess that is old-school nomenclature.

    Those were actually the IEEE (we called it the IRE then) band designations for that portion of the microwave spectrum I was taught in college back in the early '80s as well.

    Though we much more frequently used the ITU band designators ... HF/VHF/UHF/SHF/EHF

    This is why I could never quite see how DIRECTV and other services claim of "Ka band" (meaning "K above") operation completely fits since only the uplink side really falls in the Ka band proper. Both downlink sub-bands are actually in the lower "K band" range.

    Unless Ka just refers to the uplink side of the service.

    No, that launch window is for the upcoming DIRECTV-15 (along with SKYMex-1).

    Harsh posted in the wrong thread ....

    Is there a way to catch these birds (DLA-1 and DLA-2) from FL? Thanks

    Well DLA-2 (IS-31) hasn't even been launched yet;

    But for DLA-1, particularly with the standard 24 in. dish used down south, perhaps some of the xpndrs you may be able to receive off their beam edges such as the Pan-Regional 1&2 sets of xpndrs.

    But the new Regional beam xpndrs of Norte and Sur are doubtful as they are mainly focused on the northern and southern halves of S.A.

    Thanks for the reply.....Would a 48in dish give me better signal than a 36in when trying to catch these?

    yes - bigger is better, it will collect more enrgy,
    but be sure your LNBF's and bigger dish's F/D factor are the same

    Any news ? How's your bigger dish performing ? How many tpns/channels you got now?
