[QUOTE="Topper, post: 654187, member: 186250"] A PLL is a phase locked loop and it is the electronic mechanism for automatic tuning, if the system gets a sniff of a signal then the PLL is able to compensate and trim the settings electronically to strengthen and lock the signal. The signals you do recieve, you mention they appear to be the opposite polarity to what they should be this suggests that the lnb may be 90 degrees out of phase i.e. the skew of the lnb is oncorrect or as PaulR mentioned you have a Fortecstar or Icecrypt LNB and it is set incorrectly. The skew on Hispasat is in the opposite direction to the skew on an Easterly satellite. This normally does not matter with a motorised system as the dish rotates to compensate except with a polar mount, however is very important with a fixed dish system which yours 'appears' to be.
