I'm active in WSPR mode, which is a single tone as well.
Mode = "DATA A", ALC = 4 bars, PWR = 5W.
An external wattmeter shows an absolutely steady power throughout the entire 2-minute TX cycle.
The bottom cover just underneath the LPA gets pretty hot, but at 5W the KPA3 is bypassed.
Will run a test at higher power to see whether or not it makes a difference.

It would be nice to have the option to leave the KPA3 in at low power. I avoid using QRP for high duty cycle modes because I'm afraid it stresses the radio more than using 12W does.
