    Why did not you mention 12505H&V ! I still can see it while the tests are over!!
    Is this because it is a middle one ? What is the meaning of middle TP?

    - The signals near band end (12505, 12749) are beacon and/or telemetry signals, narrow band only. You won't find DVB-S there in the future.
    Edit: the 12749 may actually be 12747 (12720 + 27), and belong to normal transponder.


    Only 12505 H from my place.

    I can see 2 carriers. 12502V at 30dB in 1kHz and 12504H at 18dB in 1kHz.


    That's weaker than your plot. I can only see 12502 on CS.

    Thanks for trying s-band. :73:


    Strongest carriere under CS is 12505 H from my place, but CS shows also weaker-ring-constellation 1MHz above and below... 12504 H and 12506 H.


    Nothing on 12502 H and flat spectrum in vertical (CS).

    Strongest carriere under CS is 1505 H from my place, but CS shows also weaker-ring-constellation 1MHz above and below... 12504 H and 12506 H.

    Doh! I had the skew set so that polarisations were reversed. I've edited the original post. It should be 12502V and 12504H
