    Hi VMA,

    I have wanted to buy a Promax for a very long time, but the steep price it sells for is out of my pocket.

    That's why I decided to buy a Trimax, which only worked in DVB-S2 mode, without 8PSK, and didn't read freqs with symbol rates below 2000 Ms. So it was a limiting meter for enthusiasts. That's probably why it disappeared from the market.

    I also got an X-Finder, which comes with the whole package, i.e., S/C/T/, and although it has many interesting things, especially if you are an installer for these standards, it has one big minus. However, those who wrote a review about it do not consider it. Namely, it has latency when reading the signal, although the tuner seems sensitive. And I think this advantage comes from the software rather than the tuner hdw.

    I won't go into any more details about this device. I want to highlight some relevant aspects for someone interested in performance and less in other qualities.

    Furthermore, I have other receivers, some with sensible tuners or other functions. I won't list them because if I have to express a preference, which is no longer a secret for those who have read my DVB card reviews, I will highlight the tbs6983(/6903) card.

    Ever since I discovered in 2010 the tbs6925(then) card, but now with tbs6983, I don't miss that famous Promax, so long desired by me.

    When I discovered in 2013/2024 that 6983, together with the Crazyscan app, can offer pretty much everything an enthusiast wants, I got rid of all the receivers and meters I still have. The possibilities this card provides are made even better by the fact that it has full Crazyscan support. This means that this card is adaptable to many modifications that appear in satellite transmissions, apart from the S2X extension, unfortunately.

    It also has the advantage that you don't have to wait for the manufacturer to adapt the card to the new features that appear in the transmissions, as most of the receivers that have appeared in the last years have to keep up with these DVB cards, and not the other way around. These receivers or meter manufacturers have realized that to stay on the market, they need to integrate new features (MIS,Mi-T2, etc) or possibilities for their devices to be relevant to the market.

    One promise of DVB cards for reception and measurement devices was and is the Stid135 chip-based cards, 6903x/6909x, which have S2X extension, now known by many seekers of high-performance cards, some of them regard them with distrust for several reasons the most often cited is slow scanning speed.

    I recognize that this search and lock function is important, but if we look at what this card offers compared to all the others on the market, both are unique and cannot be replaced by others, even proprietary ones.

    Without getting too long-winded, and this is what I wrote above, the cards mentioned above are the ones that provide everything a DXer is looking for.

    I have to remember that without the Crazyscan application, first and foremost, but other other things, these cards would be like cars kept in the garage. Their excellence was and is emphasized by the formidable crazycat, which keeps an eye on them while users are working them.

    Let me add one more extremely important detail for 6903x/6909x: in recent years, these cards have shown their hardware qualities under Linux, thanks to another formidable developer, I call him deeptho.

    It is good to know, although it is evident, that my subjective opinion, expressed above, could be confirmed or refuted by those who own the above-mentioned cards. :3:

    I found exactly what qwer, feci01 found, nothing more, rather minus, 10983V.

    Oh, yes, on 11052 V, which has a weaker signal in my area and doesn't show up every time I scan. But now, in this period of cold and frost, it is favorable for visits to several positions on the arc.

    Although I searched for 10983 V, I didn't find it on qwer's spectrum (#29). :3:

    Seems that ORTC 12643 V 2061 is turned off? today its not possible to lock this frequency.

    Or they switch spotbeams?

    ORTC is receiving it in my area. It's not off, it's still being transmitted.

    I don't think they changed the beam because the signal is at the same level as always.

  • 10.0°E Eutelsat 10B

    Too much had not changed on Horizontal in the upper band as when the satellite became operational, at least in my area. I mean, Radio Maria is still on 12506 H,255,1/2.

    It may well be that on 12672 H, we have a similar transmission as on 12506 H, but it cannot be locked for unknown reasons (administrative, technical? Only IQmonitor gives us a clue as to what parameters are used.
    How is it with you, who has an even stronger signal on this frequency?

    10842 H,4984,32/45,S2X has left the satellite. Instead 10858 H,8000,1/2 was activated, which I could only lock with 6903x card and Crazyscan app. The same symbol rates found,8000, every time!

    ...

    Of all the DVB cards used for 10858 H only 6903x found the parameters and lock it!

    ...

    10844 H, 36000, 32/45, (S2X)/32APSK, Multi 1-254- Data, new symbol rate.

    I posted a screenshot instead of commenting on the constellation and other parameters of this mux, which was obtained with the 6909X card and IQmonitor.

    All apps locked this mux on auto search.

    Happy New Year 2025! :3:

    10924 H,36000,4/5,16APSK-Data, new. I locked it with tbs6909x only with neumoDVB under Linux. It's probably also with the S2X extension(?), like 10844 H.

    11634 H,23000,1/4,S2- Data, new.

  • 95.0°E SES-12

    10979 V,51417,3/5,S2-GS, new symbol rate(for 10965 V,24761,1/3).

    11475 V,14663,5/6,16APSK-GS, new,

    11559 V,3526,3/4,32APSK-GS, new symbol rate for 11562 V,6424,2/3,S2),

    11672 H,2811,2/3,16APSK-GS, new.
