47,7° East Eutelsat Quantum

[s-band]

I checked it with the big antenna. The 12523 H and 12702 H clearly come from this position. The 12702 H could be telemetry or the beacon. I don't know what the other signal is. Interestingly, I discovered two new signals on 12215 and 12226 H. But I can't unlock it at the moment.

I think that the X is probably BPSK as the CS display flips phase randomly where it should show just 2 positions. Usually, if you just run it for a short time you'll only see the 2 positions of BPSK. It may be a TT&C beacon but I can't look at the moment.

In this recent (2022) pdf, the high flexibility of Quantum is described in more detail.
All sorts of up/downlink combinations are possible, including frequency reuse.
So indeed, the entire 10.7...12.75 GHz band may be used.

The first picture is from this morning and by noon the two transponders can be received again like yesterday.

10872 V,62000,1/4,S2- Data, new. RollOff of 0.05 also indicates the presence of the S2X extension.
11363 V,4200,3/4,32AOSK-GS, new. Maybe someone will confirm this mux; I am not sure about it.
Searching in the lower band, I discover an active mux with appearances like those that have been active for longer. So a full Ku-band search is recommended.
After doing the first time (#503) tests on 47.7E with neumoDVB with inconclusive results, I returned to muxes with a symbol rate of 133000. This time the spectrum looks a bit better, but without correctly finding and locking the two muxes-11790 H and 12020 V, the two muxes with a symbol rate of 62000.
It is amazing how fast it scans 6903x at 47.7E on Linux, about 7 min; unlike Crazyscan under Windows, it seems to take an "eternity."
Interesting that neumoDVB finds a lot of beacons but without a correct identification of muxes with a high symbol rate (133000).

I can confirm the 10872 H. I can't receive anything on vertical.

Also I'm getting 10872 H 61900, for first time

47.7E_12240 H,65336,1/4,S2(/S2X),0.15-GS, new.
And some spikes in the upper band.

I'm not saying anything new, but this Eutelsat Q is the most difficult to receive. This is because of the problematic parameters, especially with high symbol rates, and because the signal fluctuates, I don't know where the source/area is coming from.
Passing with the antenna at this position is often like passing through a station/arc without an identifying sign.

Perhaps because of this, finding and locking a transponder is (slight exaggeration) a performance, even if it is no longer a novelty.
Of course, that finding doesn't make it appetizing to the program consumer. He is a "target" for those seeking rare "trophies," i.e., enthusiasts.

The novelties are 11373 H, 62000, 1/4, S2 and 12140 H, 125578, 1/4, S2. The trp on 11892 H has moved to 11902, 62000, 1/4.
Probably 11790 is still active (maybe not), but the signal is too weak with my antenna to detect/lock it.

To those who have reservations for tbs6903x/6909x cards, I advise them to reconsider this option because, for now, only with these cards can you lock symbol rate over 100000 Msps or access to DAB+s NRK at 1.0W.
With all the limitations users observe, these cards will be valid for a long time. For now, there is no other alternative for enthusiasts.
Of course, this is just an opinion.

thanks satesco

Great, @dreamsat. I was expecting you to find a new mux.
With the stronger signal, it may stand out if there is a chance of a mux being found.
You might find a symbol rate at 11790 H, or, who knows, you might find new ones, for example, in the upper band.

this is now 11801 H 133000 with a Video Content

12021 V 133000
11171 V 133000

I couldn't find a video stream on 11800 H, especially since the signal with my antenna is weaker. This confirms what you found.
But I'm glad that, considering this satellite's type of transponder, I was still able to lock it. To tell the truth, this is also a hobbyist's target, and if you get a stream with content, it's a bonus.

On this occasion, I discovered and locked two muxes, which were hard to find, especially since they were close to a transponder with a high symbol rate.

12276 H,1500,3/4,S2-Data, new,
12281 H,1500,3/4,S2,Multi 2 & 63-Data, new.

Here are the transponders found at 47.7E this year.
Although less than last year, at least I didn't pass the antenna at this position for nothing.

11373 H,62000,1/2 looks new to me, as I haven't seen it reported on this thread.

The others on the spectrum are not new, they are reported on this topic.

 

[satesco]

47.7E_12140 H, 125578, 32APSK,4/5-Data, new, with Crazyscan and neumoDVB used the tbs6909x card.

 

[satesco]

High symbol rate (133000 and 62000) transponders have reappeared on the "radar," but they do not have a constant signal; sometimes it even disappears, at least in my area, which is frustrating even when you detect the signal.
And if you don't have a card stid135(6903x/6909x), it's useless to look for them.
