“The modulator” means “the modulator code in the DSP” of course. If the compression is done by RF limiting, I expect that is also done in the DSP.
The ALC you are describing is transmitter gain ALC. That is different from audio gain ALC. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jan 31, 2022, at 12:07 PM, Andy Durbin <a.dur...@msn.com> wrote: > > "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.
