[Elecraft] ALC control of W6PQL amp from my K3

[Wes]

Indeed.  Folks who would never think to turn off the AGC in their receivers get 
weak-kneed at the thought of AGC (ALC) being used in the transmit loop.  In 
"Fundamentals of SSB", Collins radio speaks of ALC (pp.7-10,11) without any 
negativity, and in fact calls it a form of speech compression.  As in many 
things, the devil is in the details.

I suspect most of the Elecraft faithful would also be surprised to know that 
their beloved K3s use internal ALC as well as digital power control. This is not 
perfect, I've observed overshoot, power slowly increasing to set level and low 
level power jitter*.

* You need a spectrum analyzer to see this and it's unlikely to be heard on the 
air, but it's there.
