Attached some specrtum analyzer plots. It does appear that there also might be a cross-pol issue at hand as we can clearly see a peak on 12089 even on vertical, although much narrower.

Plot of vertical polarity with some sort of signal being shown at 12089 MHz on the last peak at the right hand side of the graph. We can also see the Hope channel transponder at 11995 on the graph.
