    Default rev 2.6B vs rev 2.6C-o parere

    S-a tot discutat aici ca skystar2 rev2.6B ar fi o revizie slaba /la nivel de tuner.
    AM avut ocazia sa testez si o placa rev 2.6C si am constatat
    -IN CAZUL MEU- nici o scadere/crestere semnificativa a semnalului.
    Am observat insa ca acuratetzea nivelului de semnal indicat de diverse aplicatii (alt-dvb/progdvb) depinde in primul rind de versiunea de driver folosit ( mai precis SkyNET.sys),iar parerea mea ca cel mai ok e 4.2.8( modificat de Saar pt a merge si DiseqC).

    Nu am avut ocazia sa tin in mina o rev 2.3 dar discutind cu prieteni din zone apropoate mie nu au confirmat difrente/cresteri de semnal deosebite pe aceasta revizie.
    In concluzie eu cred ca placile skystar2 in zone cu semnal redus /antene de dim mici se comporta cam identic ..iar mitul "rev 2.6B cea mai slaba revizie " e cam nerealist.

    D.p.d.v al tunerului nu cred ca este nici o diferenta intre reviziile 2.6B, 2.6C si mai nou 2.6D: toate au acelasi Samsung NIM.Singura noutate e ca 2.6C are FlexCopIIb fara de FlexCopII cat au restul revziilor mai mici.FlexCopIIb-ul aduce in plus un numar mai mare de hardware PID filters (+32).. si cam atat..

    Rev.2.3 e facuta cu demodulator VP310 (Zarlink) care fata de STV0299B (STMicro) din tunerul Samsung are cateva chestii in plus: pragul de demodulare un pic mai jos (ajuta la semnale slabe), AutoSR (bun pentru vanatorii de feeduri) si BER (indicator de calitate a semnalului).
    Chestia cu "minus" la 2.3 e temperatura de lucru: VP310 (ala acoperit de un radiator negru , mai sus de FlexCop) arde ca draq ! Am masurat chiar azi: "hranit" cu 60MHz sta undeva pe la 70 de grade .. iar daca merge la 90 MHz sta pe la 83 de grade

    Preferata mea: Rev 2.3

    @bogdani: ai dreptate cu indicatorul BER la SS2 Rev 2.6 ! se pare ca nu am citit cu atentie datasheet-ul de la STV0299 !

    Salut altxro,

    Avand in vedere ca ai lucrat cu o placa pinnacle pt altdvb, as vrea sa te intreb care e parerea ta (cat mai tehnica ) despre aceasta placa fata de skystar 2 (rev 2.6). Tunerul este mai sensibil sau nu, constrstuctie/conceptie mai buna sau nu, are vreun punct in plus sau minus?


    Multumesc,

    dp.

    PS. Nu publici pe grup la yahoo si update-ul de HT pt altdvb?

    Din punct de vedere al tunerului,pinnacle are tunerul mai sensibil decat SS2.Se situeaza intre SS1 si SS2.
