K3 VFO-B knob replacement notes
 
|
Hi, Recently I purchased a K3 and found I need to give it some love as it has been a bit behind on maintenance. One of the issues is that the VFO B knob has cracked. This is Elecraft part number E980090, listed as K3 spare part. Unfortunately, that knob is no longer available, and here is where the fun starts. What is sent instead, is Elecraft part E980275. Both E980090 and E980275 are listed but only E980275 is available. The replacement knob is smaller, the old knob is 1 3/8", the new knob is 1". Just replacing the knob won't work because the felt washer sticks out. Also, the encoder is too long and the new knob sticks out - the felt washer doesn't work. Called Elecraft sales and there is some confusion. The errata of the build instruction of the K3S (not K3) explains what has happened: - The new knob is smaller - it needs a different felt washer, replace E700033 with E700416 - the encoder needs an additional lock washer, E700150. - So, if you order a replacement, order all of this and plan to have to take the front panel apart. None of this is on the elecraft website. I also did not find anything in the reflector archives. And it's not in the K3 documentation, only the K3S documentation. This is kind of painful, since in addition to the price of the spare parts I ordered to get the K3 up to date ($173) I spent $80 on shipping, customs and postal admin overhead and I now find I have an incomplete mod kit. I will need to cut the wrongly-ordered felt washer to size and find a replacement lock washer to make the encoder sink deeper to match the new knob.. Again, this isn't listed in the spare parts on the website or on the reflector; it is now documented on the reflector, at least.

I have a spare stock K3 knob set left over from when I replaced them a few
years ago with a set of heavy CNC machined ones. Only problem is there at my Florida home. If no one else steps forward with an original replacement for you I will send you the one I have when I get home in mid December. All I would possibly ask for is the shipping. Let me know.... 73 Jeff kb2m -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Geert Jan de Groot Sent: Monday, October 14, 2019 6:00 PM To: Elecraft Reflector Subject: [Elecraft] K3 VFO-B knob replacement notes Hi, Recently I purchased a K3 and found I need to give it some love as it has been a bit behind on maintenance.

Thank you for posting this!
I recently inquired of Elecraft Support about replacing the VFO B knob on my older K3 (it is cracked). I was told to order E980275, but the person did not disclose all of the details you listed in your message, which are important. Fortunately I hadn't placed the order yet, planning to do it this evening. I don't want a smaller knob, so I'll simply repair the original knob and carry on. 73, Bob NW8L On Tue, 15 Oct 2019, Geert Jan de Groot wrote: > > Hi, > > Recently I purchased a K3 and found I need to give it some love as it has > been a bit behind on maintenance. > > One of the issues is that the VFO B knob has cracked.

Two possible replacements. Not exact appearance to original, but both are 1.25 inch diameter, and about 0.7 inch tall. Very close to original measurements.
This one is plastic. Drawing available online. https://www.digikey.com/product-detail/en/davies-molding-llc/8125-B/1722-1087-ND/6566310 This one is aluminum, and more expensive. https://www.digikey.com/product-detail/en/te-connectivity-alcoswitch-switches/KN1251B1-4/KN1251B1-4-ND/1201555 And possibly this one https://www.digikey.com/product-detail/en/te-connectivity-alcoswitch-switches/KD1250B1-4/KD1250B1-4-ND/1201657 If they would work as satisfactory replacements, IMO it would be better than having to disassemble the front panel.

Hello Geert,
I guess the VFO-B knob for the K3S will fit, doesn't it? The K3S is still available. Most probably available with a different part number. Just verify if the diameter of the ax K3 vs K3s is the same. 73's, Evert PA2KW / 5T2KW -----Oorspronkelijk bericht----- Van: [hidden email] [mailto:[hidden email]] Namens Geert Jan de Groot Verzonden: dinsdag 15 oktober 2019 00:00 Aan: Elecraft Reflector <[hidden email]> Onderwerp: [Elecraft] K3 VFO-B knob replacement notes Hi, Recently I purchased a K3 and found I need to give it some love as it has been a bit behind on maintenance.

However you work it, I tried something and
it worked/works perfectly with my K3 & K3s (which has the off-brand metal knobs). I took the felt washer and put the Teflon plumbers tape on it, I wrapped it so the felt is now unseen & the washer looks "white" from the tape. This allowed me to tighten the knob as I wished, made the feel to be just as I liked and best, there was zero sound as I turn the knobs. It was for me, a perfect solution to getting the feel and action, just right. 73, Gary KA1J > > Hi, > > Recently I purchased a K3 and found I need to give it some love as it > has been a bit behind on maintenance. > > One of the issues is that the VFO B knob has cracked.

A few years ago, when the VFO B knob on my K3 cracked, Elecraft sent me
a free replacement. Recently, one of the smaller knobs split in two. It was entirely made of plastic. I ordered a replacement, which turned out to have a metal insert. Clearly, these should have had the insert in the first place. OK, the radio is 9 years old, so I don't mind paying for the replacements, but still.... 73, Scott K9MA -- Scott K9MA [hidden email] ______________________________________________________________ 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] |
