Hi all,
I see something strange here. My TBS cards (6983 and 6522) are registering some kind of interference. either it is something wrong with my antenna or it is something wrong with intelsat1002. Can someone verify that?

first screenshot: with 6983 from 28/04/2020
second one from today with 6983
third one from today with 6522

is there a new transponder? it looks like a transponder with 6522 and 6983 is going crazy there..

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.

Today it is only on vertical and moved to 12200-12400
this interference is something really new, it came suddenly yesterday from nowhere.
