K3 RF knob Broken

Has anyone other then me had one of the inter knobs for the RF or AF gain break? Came in, turned on the rig and reached up and turned the RF gain down and low and behold the little knob fell off the shaft. It was broken right where one of the set screws was located. I see there is no brass bushing in the knob for the setscrew to be threaded into. Do you know where some better quality ones can be purchased?

Re: K3 RF knob Broken

I had the same problem, but during construction, probably over tightened the little set screw, Should remember

It is a radio not a truck

Ron,

Just send a request to [hidden email] and a new one will be sent
out immediately. It's possible that either the set screw was
over-tightened or that there was a defect not caught in QA. Either way,
we'd like the broken one back so we can get it to the vendor for
analysis.

This is a custom knob (like the others on the K3), so you won't be able
to find an exact match elsewhere.

73,
Wayne

Ron:

I've seen one other knob broken... as a result of someone having tightened the
setscrew WAY(!!!) too much! In fact, I rounded off the corners of the little
Allen wrench trying to get the darn thing loose.

Folks (esp. those building their K3s) should be instructed to 'snug' the
setscrews down, rather than TIGHTEN them.

Ron, the AF gain knob fell off here same way. Emailed Elecraft parts and they sent me one out in a very timely manner.

Hope you are enjoying your K3. Still enjoying mine & the nice rig you sold me.

I don't know where to get better ones but I repaired the knobs that broke with 30 min epoxy and they worked for a while. I called Elecraft and they sent a set under warranty and I bought two more sets. They are not expensive, but the shipping and handling is, co I bought three new sets. My outer ring broke and while I was looking at it the inner knob broke also. Elecraft could do well if they found something better quality.

Metal or Brass insert! Not just plastic.

Had two crack S/N 2324, one ea. inner and outer. Called Elecraft Parts, and replacements send no questions. Removing the cracked knobs took too much torque on the small set screws. The set screws were too tight at Factory assy I believe. I used the small end of the supplied Allen wrenches to just tighten, not the long end. So far so good. Will send in defective parts, but I believe they were just over-tightened. I checked the rest of the knobs and they were not as tight, but reset them anyway.

Small annoyance on an otherwise excellent product. Thanks Elecraft.

Inner knob here - the one on the end /w the smaller diameter shaft.
Replacement, no questions asked, in a couple days! Will be sending the
busted one back for Wayne to use /w the manufacturer.

Couldn't agree more. I received my K3 last month. Only noticed today that 3 (!) knobs are cracked (RF, AF and one of the subs). I am sure though that Elecraft will be quick in sending replacements.
