new KX-2 question
Locked
 
|
Does anyone know if the samller N8BX VFO knob “B” on the K3/K3S will fit the encoder shaft on the new KX-2?
Is the VFO knob on the KX-2 weighted like the KX-3 and K3/K3S? Very interested in hearing user reviews on the KX-2 from QST or Sherwood Engineering.

With a proper lengths set screws (one over, one under) and some
patience, the flat should preclude a centered setup... as long as the shaft diameter is the same or pretty close to the VFO B encoder shaft diameter. ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 5/23/2016 2:31 PM, Ron D'Eau Claire wrote: > It will fit, although the KX2 knob is a press-on type with a flat on the encoder shaft while the K3 VFO B knob uses two set-screws on a round shaft. > > Thanks to the flat, the K3 VFO B knob doesn't center perfectly. > > 73, Ron AC7AC > > > > -----Original Message----- > From: Elecraft [mailto:[hidden email]] On Behalf Of [hidden email] > Sent: Monday, May 23, 2016 12:11 PM > To: [hidden email] > Subject: [Elecraft] new KX-2 question > > Does anyone know if the samller N8BX VFO knob “B” on the K3/K3S will fit the encoder shaft on the new KX-2? > > Is the VFO knob on the KX-2 weighted like the KX-3 and K3/K3S? > > Very interested in hearing user reviews on the KX-2 from QST or Sherwood Engineering. > > Contact Bob, K3SRO at [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] > > ______________________________________________________________ > 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] ______________________________________________________________ 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] |

Leave one screw loose, drive the other one into the flat. How could it not be
centered?

Draw a circle on a piece of paper radius R, and mark it's centre. now draw a smaller circle inside radius r, which touches the bigger circle at one point, and mark it's centre. You'll see the distance between the centre points is (R - r). imagine the big circle is the hole in the VFO knob, and the little circle is the VFO shaft. The flat part of the VFO shaft is irrelevant, as the screw is adjusted to meet it wherever it sits.
I hope this help explain how the knob will not be centred. 73, Matt VK2RQ Get Outlook for iOS On Mon, May 23, 2016 at 2:03 PM -0700, "Wes" <[hidden email]> wrote: Leave one screw loose, drive the other one into the flat.

Bob,
I strongly recommended *not* putting any other VFO A knob on the KX2. The current VFO knob was designed specifically for the KX2, matching the exact amount of space available, and keeping it low-profile. If you add a knob that's even slightly larger in diameter, it may hit or overlay the switches or LCD bezel. If you use a weighted knob, you'll risk shortening the lifetime of the VFO A contacting encoder. It's a high-quality encoder with a specified lifetime of over 100,000 revolutions, but a weighted knob could stress the shaft unnecessarily. The KX2 has a couple of useful features to minimize the amount of VFO knob twisting you need to do to move around the band: - If RIT and XIT are OFF and the "OFS" LED is lit, then the OFS/VFO B knob will move the VFO in coarse steps. (The size of coarse steps is defined by MENU:VFO CRS). - There are at least two tuning rates available in each mode (RATE switch). - You can jump to a specific frequency using direct frequency entry (FREQ switch). - Scanning can find signals on the band -- even fairly weak ones -- without any use of the VFO A knob at all. 73, Wayne N6KR On May 23, 2016, at 12:11 PM, [hidden email] wrote: > Does anyone know if the samller N8BX VFO knob “B” on the K3/K3S will fit the encoder shaft on the new KX-2? > > Is the VFO knob on the KX-2 weighted like the KX-3 and K3/K3S? > > Very interested in hearing user reviews on the KX-2 from QST or Sherwood Engineering. > > Contact Bob, K3SRO at [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] ______________________________________________________________ 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] |

Hi Ron,
Of course, you're right, you want the set screw against the flat part of the shaft, otherwise the knob could be pulled even more off-centre. Thanks for clarifying. 73, Matt VK2RQ On Mon, May 23, 2016 at 8:00 PM -0700, "Ron D'Eau Claire" <[hidden email]> wrote: Matt: What I was referring to is that with a flat the KX2 shaft is no longer round, so the set screws can pull the knob off center unless they are carefully positioned so they pull the knob against the round segment of the shaft. The shaft of the KX2 encoder is slightly smaller than the KX3 encoder - about 10 mils - so that can contribute a small amount eccentricity as well. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:[hidden email]] On Behalf Of Matt Maguire Sent: Monday, May 23, 2016 4:52 PM To: Wes; [hidden email] Subject: Re: [Elecraft] new KX-2 question Draw a circle on a piece of paper radius R, and mark it's centre. now draw a smaller circle inside radius r, which touches the bigger circle at one point, and mark it's centre.

The solder is barely dry on the rig and people want to change the
freaking knob....Without ever having used it. Just amazing.
