[Elecraft] What happened to ALC?

[Andy Durbin]

"If so, the ALC would be before the modulator and compression after it."

I remember modulators  but there isn't one in my TS-590.  I doubt there is one in any modern rig.  In the TS-590 architecture compression is done in DSP (Digital Signal Processing) and ALC is applied way down path at a TX IF amplifier.

ALC gets a bad rap but it is alive and well in Kenwood rigs.  It works without introducing signal distortion or harmonics.  Having said that, I do not use external ALC with my KPA500.
