Same here-- mostly 3 o'clock on the AF gain with the external speaker; occasionally up to 11 o'clock. And it's a fairly noisy environment here, especially in summertime with window A/C unit grinding away nearby or windows open and dogs barking, jets flying over, cicadas buzzing ,etc.
My K3 is an older one at 2+ years. I have attached a speaker baffle inside the case but still used the same volume levels without it. I am a CW op but also listen to AM broadcast on SW or MW, same volume. Three o'clock on the AF gain control would be extreme for me, but does not blow my ears off. I DO think the taper on the the K3 AF gain control is a little weird in that I would expect the 3 o'clock position to be much louder than it actually is. But I never set it there and haven't fooled around with the AGC or noise parameters to see what difference they make. 73, Drew AF2Z On Tue, 07 Sep 2010 16:15:00 -0400, you wrote: >My K3 does not act like you describe.
