K3 VFO B Knob
Locked
 
|
There are times when I'd like to spin the VFO B knob on the K3 a bit
more quickly than its small size allows, or do so continuously without ratcheting my wrist. I noticed that the guy who sells adhesive knob dimples also offers a replacement knob with a small crank for the FT-817. http://www.fingerdimple.com/main/page_ft817_kranker.html Anyone out there know if the FT-817 knob is similar in size (outside diameter, shaft diameter) to the knob used for VFO B on the K3? Thanks es 73, Dave AB7E ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Dave,
I no longer have an 817, but I can tell you that the knob was definitely smaller than the K3 VFO B knob. In fact, I increased the size of it by installing a rubber crutch tip. :-) You might consider a K2 knob. It will hang a little low, but other than that it should clear everything else. The K2 knob is 1.5" in diameter. I put one on my K1. 73, Neal WA6OCP

Neal, I am also interested. Is the K2 knob covered by rubber, like the main
K3 knob? 73, Erik K7TV ----- Original Message ----- From: "Neal" <[hidden email]> To: <[hidden email]> Sent: Wednesday, March 04, 2009 1:35 PM Subject: Re: [Elecraft] K3 VFO B Knob > > Dave, > > I no longer have an 817, but I can tell you that the knob was definitely > smaller than the K3 VFO B knob.

Hi Dave,
I've been using a K2 vfo knob for my K3 B vfo for some months now. The profile of the back of the K2 knob is proper to allow for clearance of the fastening nut on the B encoder shaft. However, the shafts are different diameters. The K2 VFO shaft is slightly smaller so the hole must be enlarged to fit the K3 B vfo shaft. I had a machinist friend do that. (One may be able to do the same on a drill press.) I like the feel of the weighted K2 knob and also use a finger dimple on it. It makes B vfo tuning much easier. The K2 knob does not obscure the B vfo label on the K3. ----- Original Message ----- From: "David Gilbert" <[hidden email]> To: "elecraft" <[hidden email]> Sent: Wednesday, March 04, 2009 12:14 PM Subject: [Elecraft] K3 VFO B Knob > There are times when I'd like to spin the VFO B knob on the K3 a bit > more quickly than its small size allows, or do so continuously without > ratcheting my wrist.

I was thinking that having a "rubberized" knob would be helpful. If Elecraft
came out with a suitable knob replacement, I'd sure order one. 73, Gary W7TEA

The diameter of the FT-817 knob is about 13/16".
The mounting hole is slightly smaller than the K3 vfo b knob but could probably be carefully drilled out and made to fit. 73, Tony, W7GO Erik N Basilier wrote: > Neal, I am also interested.
