the same problem is here. I think that the issue is the PCI bus (Riser card
flexiple). Is since version 1.6.0 more traffic to the FF card? Another reason
is the LNB. I think that the contact ressistance from card to LNB is to high.
I have test it with femon. STR: 60% SNR: 81% Is this ok?
Any other ideas?
