    Default

    Din ce-mi mai aduc aminte
    Diseqc 1.x - un master ( receiverul de ex. ) restul salve ; comunicatie numai master->slave
    Diseqc 2.x - mai multi masteri ( ? ) si comunicatie bidirectionala
    1.0 - comutator simplu ( A / B )
    1.1 - comuta 4 variante ( A / B / C / D )
    1.2 - pt pozitionare
    1.3 - ( usals )
    Sigur si amanunte vezi la Eutelsat pe site .

    Default diseq

    am schimbat diseq 1.0 , 2*1 (pos A si pos B) 950-2150MHz

    cu unul diseq 1.0 , 4*1 (pos A, pos B, pos C, pos D) 950-2200MHz, Insertion less:[b]<3dB, Power: 12-20V/30mA

    antena cu 2 lnb(sirius/hotbird), 1.2m ; semnal aveam de la 29%- 79% pe cei doi sateliti

    dupa inlocuire am pierdut cam 60% canale, semnalul facut cam jumatate

    imi pare cam mult prea mare atenuarea comparativ cu primul diseq 2*1

    Default asa mai merge

    la ce am scris mai sus aduc corectie:

    diseq 1*4 ce a dat datele de mai sus era defect;

    datele cu disec 1*4 bun sunt urmatoarele:

    sirius T 12260000-H sgn=70-72%-fara diseq
    sgn=68-70&-cu diseq 1*2
    sgn=68% -cu diseq 1*4

    hot bird T 12149000 sgn=40% -cu diseq 1*2
    sgn=38% -cu diseq 1*4

    cele 2 LNB sunt pe o singura antena 1.2m //locatie :Vaslui

    Default

    pe hot bird,nu stiu cu ce frecventa/fec,semnalul este relativ slab si necesita maximizarea semnalului.nu uita de rotirea axiala a lnb-ului pentru
    cresterea semnalului.
