[Exede] Dish Out of Alignment
Being on fringe beam area, just a pinch out of adjustment brings about a scanning, then ranging, then ranged, then back to scanning as would be seen in Modem's Status Menu here when your dish is out of alignment.
Further, the Cable Attenuation value will vary in value from like 1 to 16 and the Rx SNR will change in value from like 10 to 0 with time. As I recall, when it reverts back to scanning, the Cable Attenuation value and Rx SNR will both Zero out within a quick moment.
