[Elecraft] K3 new GAIN knobs
Improved knobs are available now. After second time having knobs break, I told factory I would keep my glued-together knobs until they had improved ones available. New ones arrived a few weeks ago with a note saying they are now made of a fiber-reinforced plastic that is much stronger. (Although they look the same.) Mine are fine so far and I trust they will stay with the radio until it gains antique value. Windy KM5Q WAS: Re: [Elecraft] K3 potentiometer dead spots? FWIW I've just had another failure of the little AF knob. All four nested knobs were replaced already about 3 months ago due to the originals cracking, but one of the new ones has also now cracked and lost a chunk off the end. I think I saw a rumor here that new stronger knobs (with metal collets?) were being ordered - does anyone know if they are available yet, please? 73, Gary ZL2iFB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 new GAIN knobs
I didn't realize this was a wide spread problem. I received my new knob set last Friday.

Re: [Elecraft] K3 new GAIN knobs
My kit came with the new knobs. They don't seem to go onto the shaft very far. So far no breakage, but two different ones have come of while I was turning them.

Best way to get them really deep on the shaft is to hit 'em with a hammer :-) (Please don't do that. Sometimes I feel like you can't make any comment on a reflector without an appropriate disclaimer) Shoot, I haven't any trouble with my original concentric knobs (shipped on ser 2091). I didn't pull a hamstring tightening them down, and they don't fall off either :-) Grant/NQ5T __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 new GAIN knobs
This sounds like he is not talking about the concentric knobs on the AF/RF gain pots (which have a set screw). It sounds like the push on knobs used for the four mechanical encoders just to the left of the VFO knob. Those push on knobs fit very snugly and he may not be pushing them on all the way. 73, Eric WA6HHQ Grant Youngman wrote: On Oct 28, 2009, at 4:13 PM, Mike wrote: My kit came with the new knobs.

Re: [Elecraft] K3 new GAIN knobs
Sorry, but I have to meet my reading tutor now. I misread the thread. I blame it on that speed reading course I never took. :-[ I'm referring to the 4 knob set [shift,width,speed,cmp].

Re: [Elecraft] K3 new GAIN knobs
100% correct Eric. I've pushed pretty hard. I don't want to push the shaft thru the encoder... As close as I can measure, they're off the front panel 3/32. That on all the way? 73, Mike NF4L Eric Swartz -WA6HHQ, Elecraft wrote: This sounds like he is not talking about the concentric knobs on the AF/RF gain pots (which have a set screw).
