These modes are confusingly named. The transmit power is the same in
both; what changes is the power consumption. Better to think of it as
high vs low duty cycle. I don't recall the low power duty cycle for
sure, but it's something like 40 seconds on/2 minutes off. This
happens automatically during eclipse.
