Yes, on short (few minutes) sweeps it is clean. During long time run, with 100 Khz resolution, if we run few hours we can catch anomalies on the carrier. Important note: this snapshot done on spectrum analyser in Europe, same transponder, and results similar, so it looks like interference is on transponder. Issue start to affect us at same time when people in Lebanon got local interference issues. Here is snapshot of carrier spectrum with anomaly: http//www.nuclearcat.com/PICTURES/interference.jpg
