DirecTV frequencies per transponder and per orbital?

    Sorry, got pulled away yesterday on other business ... :)

    But sure as they all still fall within the 19.7-20.2 GHz range and will translate down to somewhere in the lower edge of the same 1650-2150 MHz LNB block.

    Actually this is the essential goal of using satellite co-location where all the birds located at a given orbital slot are close enough to be seen by the dish and receiver as one big fat satellite at a "nominal" orbital slot with various combinations of frequencies and/or polarization to separate all the channels assigned there.

    Specifically which satellite though is transmitting what particular channel at a given "nominal" orbital position is really only the concern of DirecTV network operations of course and the interested techno-geeks on boards like this. :D

    I will add them to your Excel document for my personal records thank you. Though I may ask gct if he would like to pin this document for download on his regular transponder mapping thread.

    OK;

    Sorry for the long delay, but again was away on personal business. Attached is the corrected transponder center frequency file with the Spaceway frequencies added assuming that LyngSat's data on them is accurate considering the Spaceway satellites are a little weird.

    What meter are you going through all this trouble for?

    Oh and if you want it, it appears that again trusting LyngSat's data, the DirecTV International ("WorldDirect" service) channel center frequencies at 95W on Galaxy IIIC use the commercial FSS Ku band listed at;

    http://www.lyngsat.com/95west.html

    Which would then use the standard LO frequency of 10.750 GHz.

    Are you looking for the intermediate frequencies?

    We could probably help you with the IF information for a "legacy" LNB but even this depends on what signals the meter is sending to the LNB (signal voltage and presence/absence of a tone).

    The data you're after simply don't exist in the new SWiM domain in terms of a one-to-one mapping of IF to transponder.

    That was nice of them.

    They may serve you well for a "legacy" LNB configuration (assuming your meter is capable of sending the appropriate switching signals).

    Actually the meter is able to send the switching commands and I can also enter the LO values for whatever LNB I am using.

    So... anyone can confirm me which tables are correct?

    Thanks!

    You got everything from the thread - go forward and give us results from a field.
