I have also noticed this with the K3. You must run compression to get much of an average power output. I notice at these levels you seem to be overdriving it according to the alc meter but it still sounds good on another local receiver and reports confirm this. With no compression and a higher output electret mike, everyone says I need more audio especially if the band is noisy.
