Ok guys...now calm down!
I shouldn't have said anything.
The K3's audio is just fine and there's plenty of it.
I was just comparing it to the IC-7000.
I never use internal speakers.
Yes I know about the hi/low setting in the menu and yes I'm using an 
efficient speaker and no I'm not deaf. I'm just saying that some other rigs 
have more AF power and perhaps there is a reason.
Looking at the K3's specifications, I don't see what the AF power rating is 
so it's hard to compare.
So YES....The K3 has plenty of audio....at 8:00 o'clock or whatever....Of 
course at 11:00 o'clock I do turn it down!
