[QUOTE="deeptho, post: 1144435, member: 215446"] Which is also a difference of 1550 Mhz. Then it is not the lnb . There is some gain control going on, so the lnb (or the card) compensates for the reduced signal. At the same time noise is also suppressed and apparantly the next effect is increased snr (because the high frequencies are more attenuated) If it is not signal level related, then it is also possible there is something wrong with your card. I tested my self on 6909x and did not see any such problems. Of course it could also be that 6903x is designed differently. Still, if this is not a problem of an excessively strong signal, then it should not be like this It could be as simple as some capacitor or inductor somehere failing, not soldered well or ... Or perhaps some driver bug (but then I would have seen it in my own tests). A simple solution would be to insert a splitter "teresstrial/sat". Normally the terrestrial signal would be surpressed in the satellite output. Why not ask TBS's opinion? [/QUOTE]
