I retried the measurements changing "PA NOR" to "PA not 
installed" and "PA not installed" after power cycling 
(rebooting) the radio. Most numbers differed only by one in the 
least significant value. [Welcome to digital measurements. :-)] 
The 10 watt measurements were 40mA less than yesterday, 
3.49A at 10.3V vs. 3.53A at 10.6V but the difference isn't very 
significant and may be explained by the difference in voltage. 
(However, I would expect higher current with less voltage.)
