Okay, but sometimes the changeover point is 5 watts instead of 3 -- what's
going on in those cases?
Cheers,

There are two windings on the PA output transformer: 1:1 and 1:4. We select one
of these based on power level, battery voltage, and in some cases, operating
mode.
In the 1:1 setting, the PA drain impedance is 50 ohms, making it more efficient
for at power levels, reducing current drain.
In
The manual states in a couple spots that the KX3 can transmit more
power-efficiently when output power is at or below 3 Watts.
Why is this? Is there an (additional?) amplifier stage that is bypassed at
these lower power levels?
Thanks,
Julie
