Weighted Knobs in K3?
Locked
 
|
Before I install 73inc weighted knobs on my K3S, is anybody of the opinion that these knobs cause long-term damage to the PTO shaft? These knobs are quite heavy, compared to the factory ones.
Seems Elecraft used lightweight knobs for a reason. Input appreciated. 73, Ed NI6S ______________________________________________________________ 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 Message delivered to [hidden email] |

I've been using a pair on my K3 since about 2011 and also have had a
pair installed on my K3S for just over a year now. Zero problems. The tuning feel with the weighted knobs is wonderful. Go for it. 73...

Ed,
Whether the weighted knobs will cause pre-mature wear to the encoder bearings is undetermined. However, I would caution you to remove those heavy knobs before transporting or shipping the K3. Any vertical bumps can cause the extra weight to bend the encoder shaft and create "rough spots" in the knob when rotated. 73, Don W3FPR On 11/14/2016 8:32 PM, Ed via Elecraft wrote: > Before I install 73inc weighted knobs on my K3S, is anybody of the opinion that these knobs cause long-term damage to the PTO shaft?

Be aware that if you ship the radio, you will want to remove the heavy
knobs... If the radio is man handled, the the moment of inertia, (for lack of a better term), can get quite high when the package is dropped, and break the encoder shaft.

Ed ...
They've been installed on my K3 for 9 years, and on my KX3 ever since it came out. No problems so far. The company is 73cnc, by the way. Not 73inc. They no longer make the spun aluminum knobs for the K3, unfortunately. Just the plain black ones. 73, Kent K9ZTV > On Nov 14, 2016, at 7:32 PM, Ed via Elecraft <[hidden email]> wrote: > > Before I install 73inc weighted knobs on my K3S, is anybody of the opinion that these knobs cause long-term damage to the PTO shaft?

While we're on the subject of protection for the K3, back in the fall of 2007, when we were asked to setup a display table for the newly released rigs (sn 008 & 021) for the Lebanon Hamfest and in a quandry as to how to transport them safely, the late Tom Hammond (N0SS) came across military surplus night-vision goggle cases that are just perfect for the K3. I see they are still available for $25. At least the site is still active. I wouldn't drive an Abrams tank over them, but they'll survive darn near anything less. http://www.armysurpluswarehouse.com/military-issue-unique-items-odds-and-ends/military-aluminum-pressurized-case-night-vision-goggles-storage-case.html 73, Kent K9ZTV > On Nov 15, 2016, at 6:07 AM, Dave Cole <[hidden email]> wrote: > > Be aware that if you ship the radio, you will want to remove the heavy knobs... > > If the radio is man handled, the the moment of inertia, (for lack of a better term), can get quite high when the package is dropped, and break the encoder shaft. > > Dave ______________________________________________________________ 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 Message delivered to [hidden email] |

Used one for years. Never had a problem. The encoder is not THAT
fragile. The extra weight is very pleasant to have. 73, Doug -- K0DXV On 11/14/16 6:32 PM, Ed via Elecraft wrote: > Before I install 73inc weighted knobs on my K3S, is anybody of the opinion that these knobs cause long-term damage to the PTO shaft?
