The problem with that is that 10dB of control range is far too small to
accommodate the variations in the audio level coming from the
microphone, as the operator moves closer or farther away, and speaks up
or speaks softly. And to maintain the 10dB compression you first need to
have a stable audio signal. So, in order to achieve that 10dB
compression, you need to place this compressor after an automatic gain
control system

Operators are cleverer than that. It's easy to keep an eye on the metering and keep the Po and the ALC in the ballpark - that's just normal use of a SSB radio - for those who get it anyway.

People who use no compression, minimal Po and no ALC don't get heard. They either figure it out, take advice, or they go back to doing the same thing on the local 2M repeater.

Then there are other AKTTR ops who always run processor and just lurrrrrrrve to ping their needles against their stops. Too bad they sound like gestapo orders barked in your face with a bullhorn at 1 meter. I just ask them to turn it down.
