    Active again: 10966 H -> there was a wide TP a short moment earlier (regarding from position 30.5°E)

    PS1: Not new, wellikan on sat.dx-club 11.05.2021 :3:

    PS2: ...and on 10.05.2021, one day earlier, on satclub.pl reported by mortodontus :3:

    /edit: another spectrum (wide again now)

    Thanks to John on SatsUK. I see something on 13400.9978 +/-5kHz V using an unlocked 11.3GHz PLL SMW LNB with about 2.5dB NF at that frequency. It peaks in the same place as the Arabsat 6A beacons on 12749 V & H (H is about 2.5kHz above V), I can't see the Turksat beacon on this LNB.

    Thanks to John on SatsUK. for 13428 V earlier this morning.

    /edit2: Here my horizontal scan on 1,2m. Peak was on 13416. Nothing here on 13401 V. :3:

    • Offizieller Beitrag

    13428 wasn't on when I just looked. I thought I might see some transponder noise but I can't.

    There is about 0.5dB excess ground noise at 24.1 deg elevation

    13428 V on again (linear vertical scan here)

    /edit: This time I can see beacon 13401 V with poor signal... better on 13408 V... :26.

    13428 V is varying in level. Magenta is max held and blue is live. The marker shows the instantaneous level of 13428. It looks like TP noise is present when the carrier is at maximum (max gain?). The signal at 13560 is the fundamental of the synth appearing in the IF.


    Here is a time domain plot of 13428V (200kHz RBW, 10Hz VBW)

    Looks like they are testing on Horizontal today. There were short bursts on 13628 and in 40MHz steps below that. This plot was taken slightly off vertical. Live = blue, max held = magenta. (13560 is spurious)



    This may show a swept test but aliased by the analyser sweep. Now set to horizontal with a faster sweep.

    They are testing with some mod on 13428V and 13628V. I'm not sure if it's DVB or something else. The carriers are not simultaneous with mod.

    Thanks s-band and I can confirm 13628 V too here. Also 13428 V active again. Both "on" for a few seconds only at this time...

    qwer and on 13508V, as you say, only for short periods.

    There was also a carrier on 13650V last night whilst 13628 was active.

    The beacon, 13401V was at a very low level earlier this morning but is back to the previous state now.

    Below threshold on my 1.2m dish but the 1st DVB that I've seen. They were only on for a couple of minutes. By the shape of the response, there may have been a 3rd signal in there.


    13444V 2800 3/4 8PSK

    13446V 1300 5/6 8PSK



    The spectrum is at the point, on the waterfall, where 13628V at the same time as these DVB signals. There is also a dot at 13428 where that was on for a few seconds. The beacon, at 13401V, varies in level. (13560 is spurious)

    Active at this time - reported earlier by s-band: 13508 V and 13650 V - first time for me. Also on: 13428 V and 13628 V.

    /edit: 13401 V later.

    • Offizieller Beitrag

    13401V beacon has been varying up to 20dB

    13428, 13508 & 13628V have been pulsed ~10sec on at various levels

    13650V has been on at various levels

    Plot time is UTC

    Checking again, some tests have been horizontal

    I hope that they are not feeds from 30.5°E !!!

    flie They look similar to the bursts on extended Ku
