• thank you very much Satesco for reply
    I will tray with an other streamreader with TBS6903X


    As for the card TBS6903X , I usually use it for a long time !
    So, temperature is the same for both programs Crazyscan and IQmonitor .
    Now my card is under the Graphic card in PCIe N°03, So I will try to put in PCIe N°01 which is closer to the processor fan, you know I don't have an fan for TBS6903X :35:


    for IQmonitor with this card I use scan with "dF and with auto SR" most of time for full Ku 10.7-12.75 GHz...yes it take time but it works :73:,
    I have to be patient :18: .


    regards
    flie

  • just to see the deference here between TBS5927 and TBS6903X


    in GS analysis (Packetized single CCM ) TBS5927 is better! :28:

    I don't want to discuss and compare another dvb card and 6903X card.I said on another occasion what is the problem with 6903x.
    What you showed above,the difference in stream types between 6903X and 5927 is not so much about the card as how StreammReader reads/interprets this stream.And as most of them are generic,they are essentially encapsulated. crazycat did nothing but put them all under the same umbrella,so to speak,for 6903X/6909x cards when you use his library,specifically StreamReader.
    Of course he also gave the solution,namely,disable TS encapsulation with option FrameMode=1 in streamreader.ini.
    Here's how streams look enable(encapsulated) and disable(generic) FrameMode for 6903x on the same transponder.

  • a very useful option in Crazycat's Streamreader :73:

    I wish you spectacular results with this card :72: Who knows, that once the fan was removed they released the" steroids " to the chip STMicro stid135,that is the extraordinary potential that it has.That means ultra-fast scan,faster signal lock and other wonders
    As for the temperature,you can check out any time you want if you look in the StreamReader file in Crazyscan.

  • Official statement from Tenow company I got my hands on to clear rumors about TBS 6903X card:


    "We have updated TBS6903-X to Version 2. After lots of testing, we decided to remove the fan on the updated TBS6903-X tuner card and used a bigger heat sink."


    So it means, 6903X has gone fan less, the heat sink was improved and all new stock is just like that.


    So if you prefer a fan version, you have to ask a dealer if they have fan, or fan less version in stock. If it isn`t available anymore and you still prefer a fan a small DIY will sort out the problem.
    Or what I`d do is to improve an air flow in the PC case.


    One way or another you`ll still buy original and reliable TBS product.

  • Live gives us lots of opportunities, but also challenges us and the brave ones are those, who take those challenges up.
    TBS has recently introduced a new version of this popular card, so Peon decided to try the new card called "version 2" out.
    For now he has a few pictures of version 1 vs 2 to avoid speculation, that a new fanless card may be a "fake".
    So far he can say that it`s a rock solid device. Exactly as the older version of this card is.

  • For those who have version 2 of the tbs6903X card,can now install the new driver version,3.0.0.1 from 28.07.2020.
    I am waiting for reactions from those who have this version.Thanks :3:

  • Due to high sensitivity of the StiD135 demodulator (which is available into DVB cards such as TBS6909X TBS6903X) to electromagnetic interferences and certain currents tensions I have managed to add and solder an extra 22uf capacitor to bridge the 13D and Y1 pins.

    This small workaround will help and stabilize much more exact locks on different transponders on heavy load conditions ,will solve some of the continuity errors and most important it will solve i2c errors reported by dmesg in Linux and few more other issues.

    The credit for this workaround/fix belong to a friend of mine which happens to work with Dektec and they managed to successfully stabilize as well their StiD135 based ultra professional DVB pcie tuner card.

    After I tested the workaround successfully on couple of TBS cards I have shared with TBS crew the results and decided to share also with the community.

    Below you have the way I made the change on both cards. Fortunately,I found this capacitor-CL21A226MAQNNNE-at a store in my city.Then I found out I could order online from here:https://ro.farnell.com/samsung…p/3013459?CMP=GRHB-SF-BNL

    After I welded the capacitor,I did a first test on transponders where I had before much noise in signal.From at that moment the noise/signal ratio improved significantly.And I immediately noticed this improvement on some transponders that I had problems with.

    I checked with 6903x card at 33.1 E,on 12543 V,1704,5/6,8 PSK-Sky TG 24 and 74.9 E on transponder with S2X extension,on 12400 h, 68568, 23 / 36s2x / 16APSK.

    Hi satesco That's very interesting. Is Y1 a TCXO? If so, I presume the extra capacitor is to decouple its supply. Is that correct? or is it decoupling the line with the diode with the connection to Y1 being ground?


    I don't have a -X only 6983/6903 which have a 30MHz crystal with the oscillator on the main chip. Perhaps it is worth adding some more decoupling to the 6983/6903

  • I'm sorry I can't go into detail,because I got the tip from someone who wants me not to divulge how I found out.I was satisfied with that,although I wanted to find out more,because some things,he told me, are under NDA, and so do not ask him to tell me more.Finally I was satisfied with that, because it was important for me to solve a problem that I noticed earlier on the two cards with Stid135,namely an instability at some high frequencies when I used them intensively and for a longer time.

    On the other hand,I have to tell you that there's no need to change tbs6983/6903 cards because it's based on chip STV0910.They work perfectly with the demodulator that they have,and so no changes need to be made.

    I'm talking here only about dvb cards that have STiD135 chip!

    Thanks for your reply, I understand. ST are a pain as they tie people up with NDAs and it is very difficult to get any information on many of their chips. I'm presuming that there was a lot of noise on the supply to the TCXO which translates to poor LO phase noise and a degraded SNR. That will be especially noticeable on narrow signals and things like 32APSK etc as you have shown.

  • Endlich fand ich wieder Zeit, mich mit dem IQMonitor zu beschäftigen.


    Der Ärger war groß - nicht über den IQMonitor, sondern über diese TBS6903x Karte


    Mit gleichen Einstellungen, gleicher Antenne, gleichen LNB startete ich einen Scan auf Astra 19,2E vertikal


    Die TBS6925 benötigte am alten PC 6'30", die TBS6903x am neuen Rechner eine unglaubliche Zeit von 1h11'20".


    ***********************************************************************************************************


    I finally found time again to play with the IQMonitor.


    The anger was great - not with the IQMonitor, but with this TBS6903x card!


    With the same settings, the same antenna, the same LNB, I started a vertical scan on Astra 19.2E


    The TBS6925 required 6'30 "on the old PC, the TBS6903x on the new computer an incredible time of 1h11'20".


    Wer nicht die Antennengröße und den ungefähren Standort angibt, postet sinnlos, sofern es um eine Signalerfassung geht.

    If you don't specify the antenna size and the approximate location, posting is useless if it's about signal acquisition.
