[Elecraft] noisy VFO's

[Dale Boresz]

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...
