Hello Natan, I can hear the same thing here. Decent high frequency hearing and a reasonably quiet shack are prerequisites to hearing it though. It's a 'shhhhh' sound that occurs as a result of the surface of the knob dragging against the felt as the VFO knob is spun. I've considered applying a light coat of mineral oil to the felt washer to quiet it down, but haven't tried it yet. NOTE: I am not recommending this; I was just thinking about trying it...
