So here’s the same data on the 15 MHz and 10 MHz output’s on a single box. 

The phase plot shows that there is indeed some sort of spur coming and going on at least one of the inputs. Based on the plot of the 10 MHz output from a couple weeks back, it’s a good bet that the spur is on 10 MHz. It also shows that there would be “good times” and “bad times” to use the 10 MHz output. Your results using this as a reference would be very different around 3,000 seconds compared to around 5,000 seconds.
