    will start by mistakes:


    1. in first attempt i had chosen Arctic F9 PWM -

    it looks extremely same to Arctic F9 TC,

    but were so loud - i were able hear it from ~4 meters and from 2 with added resistor



    2. this mistake isn't made by me,

    i can't even describe my disappointment about place where socket is located



    installation:


    fold the socket legs


    cut connector body


    add two layers of tape on connector

    and two layers of tape on HDD/SSD bay



    add small distancer


    use screw with flat head


    i skipped such screw at all in next boxes



    connect Arctic F9 TC to resistor and place it little angled on the radiatorbit



    fix cooler by small piece of black tape


    bedroom edition


    hide HDDD/SSD bay



    TC means Temperature Controlled

    well, i have measured also ohms

    Code
    Cable;    20k;    200k;    2000k;
     1    11.05    52.2    239
     2    11.43    52.5    233
     3+sp    -    105.6    462
     3    -(9.?)    31.5    077


    `3+sp` means cable_3 had two way splitter to able leave one free end for temporary guest boxes


    after remove splitter, situation improved, but still abnormal

    NOK - no picture at all

    nok - huge pixelation


    why problem isn't gone?

    resistance of the cable_3 is hugely improved and became even better than cable_1



    configuration not simple at all,

    most popular LNBs are Octo, which are cascaded through 4x1 switch(protocol 1.0) and 1x10 some 1x8 (protocol 1.1)

    [User = '15731'] dhwz [/ user]

    1. that are so sad news, problem long time known and no solution :frowning_face:


    2. till now, i thought signals under 10dB can be defined as weak.

    most of 19E are between 11 and 15dB, just few transponders are under 10

    and 36E have between 12 and 17dB


    p.s.

    but THANKS for link!

    also no problems when connected two identical cables to same Si2169D

    what logically cancels idea about `Internal Loop-Through`,

    can't believe option `Equal-To`, also previously used, can be guilty, but what else..


    p.s.

    system log is saved, ask if needed

    that also isn't power supply problem, measured voltage on cable_3:


    Cable_3 A1 19E 10.744 H 1_0_1_7035_41B_1_C00000_0_0_0 PHOENIX

    signal 13.0dB while alone on main screen

    voltage on cable_3: 17.8v

    signal dropps to 5.75db immediatly after activated PiP

    Cable_1 A2 19E 10.876 V 1_0_1_7790_424_1_C00000_0_0_0 CALLE 13

    voltage on cable_3: 12.8v

    signal dropps to 0.00db immediatly after activated PiP
