    A new AEHF location, at about 54.65°E.
    Now the AEHF series is complete:
    111.0°E (incl. 0.6°): AEHF-3 (USA-246)
    54.65°E (incl. 5.9°): AEHF-5 (USA-292)
    04.0°E (incl. 2.8°): AEHF-1 (USA-214)
    67.6°W (incl. 2.1°): AEHF-2 (USA-235)
    150.0°W (incl. 3.8°): AEHF-4 (USA-288)


    103°W (incl. 7.5°): AEHF-6 (USA-298) was launched in March 2020 and is still slowly drifting West.

    I have tried to find something from TDRS 6, 9, 12 & 13 but only listened on RHCP at the time (13-16GHz). As far as I know, there have been no reports of reception in Europe. The theory put forward is that the space-Earth beam is directed towards White Sands, USA.


    I think linear pol. (both H and V) is used, according that old pdf I linked to.
    TDRS 13 at about 11.4°W is below horizon for White Sands, New Mexico.
    Then probably will downlink to Blossom Point, Maryland.
    Good luck! :126:

    Hi flie, just a note, Inmarsat-5 F5 (also called GX5) recently arrived at 28.0°W.
    The satellite should have been tested already at 83.8°E.
    The question is, if 28.0°W is a final location where it will become active. It was thought final location would become 11.0°E.
    Or it is just an "in-orbit spare" or slot reservation at 28.0°W, without much activity!

    Now here also constellation diagram at > 13 dB, only the right column (with Pilot, Frame type etc.) stays grey.


    Edit: 11587 V 2300 in the scan above is from 66°E.

    Wow, you can go to -20° inclination with actuator, or manually pointing the dish?
    I wonder where the signal is strongest, maybe the footprint will change a lot depending on inclination.


    Looks like only the R transponders are active/received this time, or the L ones are weaker.

    Is it already over 3.5 years without checking this one? :87:
    But maybe nothing changed since then.
    During the belt crossing, I saw almost the whole 12.2...12.7 GHz spectrum raised so probably all txps are still on.
    Here, Crazyscan found just 3 "no locked" ones: 12224, 12253 and 12384, all SR 20831, 16APSK 5/6.

    I can't lock 11230H with 2.1m but with 3.4m :73:
    Nothing active ATM


    This could have been when you tried, but now all is active.
    Note that the TBS USB tuners can not stream the high bitrate of these two transponders, see the discussion above from EnoSat.

    It's still not clear if Feedsat received DSCS-3 12 (inclined 6.3°) or WGS-8 (non inclined) back in 2018.
    If you read this Feedsat, do you remember if the satellite was inclined?


    Meanwhile, DSCS-3 12 moved to 134.3°E, and WGS-8 moved to 149.8°E.


    Indeed qwer, we have WGS-9 (non inclined) at 56.8°E now.
    Does your spectrum have peaks coming from that direction, or are these just "background" peaks?
    Since 56.8°E is so close to 60.2°E (WGS-2), WGS-9 might be an in-orbit spare at the moment.

    hvdh - 11663 V is listed on fs as data , so the other will be probably data too. :72:


    Yes, I overlooked on Flysat because that frequency is not sorted properly!


    Added last night's scan of 10.95...11.2 GHz to my previous post.
    6.5 dB on 10969 V is "too much" for my small dish, either I'm at a lucky location, and/or nighttime is the best time to chase a lock.

    Intelsat 903 arrived at 31.5°W in October 2017, when it also started to become inclined.


    A few days ago, started drifting West at graveyard altitude.
    For now assuming the satellite is end-of-life, although it should be 2030 according Intelsat Form 10-K. That will be either a typo, or a later revival planned with a MEV.


    Intelsat 25 (launched 2008) is still at 31.5°W without inclination.
