I normally wear a headset but when working I like to listen to code to help
build my proficiency and am hearing a lot of distortion/buzz/whine. I
typically am on 40M running about 500Hz wide (my filter is the 8 pole
400Hz), NR is ON, APF is ON. I've tried changing the tone from 700Hz to down

Jerry,
I have this buzzing in my K3, and have heard it in some (not all) of the
K3s I have built for friends. I have found that most of it comes from
vibration between the case top and the vertical metal pieces that contact
the top. If that's what you're hearing, you can minimize it by putting som
Outstanding!! I’ll try that. I don’t listen to my rig often over the speaker as

I use a 60 degree deflector made from 3" ABS plastic pipe that sits over the
stock top mounted speaker. This gives a noticeable boost to the
