The JDAST indicates problemns I wouldn't want. Namely the jitter.

The 1.4 dBmv difference in DS power between highest and lowest channel isn't a problem IMO. The horizontal scale isn't labelled properly - so if the dips are during the day, when it's warmer, then the lower power (a drop of c. 0.6 dbMv) is about right if weather conditions on the 4 day period match.

The SNR graph is fine. It's the number that matters not the minor variance. If you're up in the 40s, there's more than enough signal to overcome downstream noise.
