    Just swapped my mates openbox s9 to a vu solo , now all the sly HD channels break up (Sports / 3d / sly one) although espn BBC HD etc are ok , seems to be all horizontal frequencies? signal jumps from 90 - 50 - 0 % over and over , any ideas? , maybe a 20db booster required? , its a communal system , AGC is 45? , dunno what to suggest to him? could it be a dodgy tuner in vu+ , all SD channels are fine??

    most tuners have a maximum input level ! l dont have a VU so i cant look at the specs !
    if the signal is too strong coming out of the system amplifiers that could cause that kind of problem !
    If the vu has a sensitive tuner it might not like the levels that are being recieved at the outlet if there above its maximum input threshold !
    Lots of blocks have systems with varying levels depending where the flat is in relation to the systems switches/amps !


    Try it out on another dish at your house to establish if it is the tuner or not !
