Re: [Elecraft] noisy VFO's
My just built K3 also makes the same noise. It's the felt washer rubbing against the back of the knob. I was tempted to push the washer down around the nut against the front panel but, the manual isn't exactly clear as the whether it should be applied this way. I laid the felt washer on top of the nut since the hole is the middle of the washer isn't big enough to go over the nut. Is the felt washer suppose to go around the nut?

Re: [Elecraft] noisy VFO's
Recently, my VFOA knob got a little wobbly, and then it started dragging heavily, only when turned clockwise. I took the knob off and discovered that the top one of the two control nuts had worked loose entirely, and the bottom one was loose. Tightened them back up and readjusted the drag, and everything was fine again. Perhaps yours is another variation on this theme. 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com, spots at telnet.reversebeacon.net, port 7000 AND now at arcluster.reversebeacon.net port 7000 On 12/13/2011 11:40 AM, Keith Heimbold wrote: My newly acquired K3 makes this VFO noise as well for the VFO A knob.

Re: [Elecraft] noisy VFO's
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 'sh' 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... 73, Dale WA8SRA On 12/13/2011 11:03 AM, Natan Huffman wrote: Hello All, Last Friday I took delivery of a new K3 along with a P3 and lots of accessories including Fred Cady's book on the K3.

You might try wrapping the felt, torroid-like, with Teflon pipe thread tape.

Re: [Elecraft] noisy VFO's
I have only had my K3 since January but no noise. I have mine set pretty loose. I wonder if you could turn the pad over. If that stops the noise maybe just replacing the pad would work.
