I have the same buzz, and no question it is not the case. I find it particularly irritating when I have the built in voice keyer running and am in a quiet shack. I can almost make out my voice from the sound....
My GUESS as I have not yet held it down while transmitting (my rig is at Elecraft for unrelated repair work), is that the heatsink for the internal amp is making the noise....at least the noise is coming from that area. Although I have to agree that everything in my rig also seems very secure to the touch. 73, Tom-N2YTF Brett Howard wrote: > > Can you damp it by putting your hand on any of the chassis panels? > > ~Brett > > On Sat, 2009-07-04 at 04:55 -0700, paulb wrote: >> Hi folks >> >> K3 going perfectly fine here. >> Just curious about an odd audio buzz >> in the rear of the chassis under heavy >> SSB modulation.
