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.
