GA Guys, 

I thought I would pass this on since you have both speculated or commented on possible interference from the Galileo satellite system. It does appear to be present. I am in Arizona USA now and have noticed a couple of times where a signal will come drifting through the frequency...once on 1296.060 and today on 1296.100. The carrier was very clean and smoothly moving slowly across the frequency. Today I captured a screen picture of the carrier trace...its was stronger than that ....when I pointed the terrestrial antenna more closely. There appears to be multiple carriers about 12 kHz apart so not a big problem for interference potential, however with an EME antenna pointed at it , maybe the potential for overload is there?? See the link below for more information on the satellite system
