[QUOTE="s-band, post: 1089549, member: 407744"] Initially it looked like IF interference since it is on both polarisations. However, the frequencies, with fur, are slightly different at 1425 low band and 1585MHz high (assuming standard LNB . To check for local interference, try connecting an antenna directly to the card input (even a bit of wire). Is the interference always in the same place? Is there an intermittency in the LNB feed. You would see more if you set the vertical axis to fill the screen and more detail if set to 1MHz steps, especially the narrow band and GS signals around 11100V. I've added a spectrum of those. One or 2 are burst mode. I don't trust the scan from the chip set used in the 6522.
