My K3 does not act like you describe. I can blow my ears off with the external speaker set to 3:00. Regardless of the NR/NB settings and I've played with the settings for each. This with extremely weak sigs from mid east on 80 and with width settings down to 200 cps. 9:00 with cans and 11:00 max with speaker, usually less. Perhaps there's two groups of K3s out there having different characteristics. Mine is #4495. I have not changed the factory settings for AGC at all. I have played with the NR/NB settings. I've found that although the NR does attenuate the background noise, it improves the SNR such that my speaker/headset controls remain pretty much the same as w/o NR or a tad higher. The gain adjustment on the narrow filters is positive of course.
