Better numbers than my pre-production hardware from April, I’m seeing my sense report ~87w averages with 75-110w being normal. Interesting, I see peaks around 150w this week with heavy clouds, good ‘ol ku bands being affected by the weather I expect. Last weeks heavy thunderstorm caused frequent loss, but no total outage at least.

I wonder if it would be possible to run less of the phased array much of the time, let portions of it sleep when it wasn’t trying to move lots of data? Definitely don’t know enough about the system to know if it could operate that way, just speculating.

The terminal consumes more power in receive mode than transmit, funnily enough - because it needs to do more “driving” in order to create a receive spot beam.
