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.
