With all due respect, pal, that's what you get when you turn the Automatic GAIN
Control OFF... you no longer have automatic gain 'leveling' and then 
are completely
dependent upon MANUALLY controlling the AF GAIN!

However, there IS a setting in the K3 CONFIG menu [AF LIM] which will allow you
to limit the amount of output when you turn the AGC off.

Hope this helps,
