We aren't talking about the amplifier linearity -- we're talking about the rig's power level being linear with the input audio data. That's how you ensure you aren't into the ALC compression.It all

Thanks for all the input. But I am afraid I don't really follow....so keep it coming, please.
In most WSJT-X modes the amplitude is constant, so there is absolutely no need for RF amplification to

Hi Steve,
I've been running my FT-897D remotely in the garage with rigctld and
network audio streams. This works OK and while I haven't had reports
of audio issues, I haven't had a chance to set up

That's one thing I do with everybody I work with is ensure linear operation.
So if you have 100W at full scale in WSJT-X then taking the power slider down in 3db increments will halve the power each

Steve,
Another thing, maybe more useful for QRP, is that if ALC is not working then the WSJT-X power slider will reduce power linearly.

I should have also said....
If you can generate 90W into your rig set at 100W with no ALC is the extra 10W going to really help? The answer is no.
Unless you can monitor your own signal to ensure

Nothing to do with transients.
Has to do with rig calibration, ALC feedback circuit, and the level at which ALC starts attenuating the signal. Then it is how does that level relate to clipping

There seems to be "received wisdom" that for non-Elecraft radios one must operate WSJT-X modes with no ALC action. Having recently acquired a new Yaesu radio, I found a variety of videos and
