Weighted Tuning Knobs - Any Consequence?

All,

Does anyone know of any issues the extra weight of the "weighted spinner
knobs" such as these...

http://www.73cnc.com/73cnc/elecraft.html

...might cause the bearing points of the tuning shaft in the K2 or K3?

Thanks.

John

Yes, you'll be about $100 poorer and have made absolutely no improvement to the performance or capabilities of your transceiver.

Hey John,

I put them on my K3 and K2s about a year ago. No problems that I can tell. Nice and smooth.

For everyone info, the stock K3 B vfo knob makes a great VFO knob for the K1.

For everyone's info, the stock K3 A vfo knob makes a great K3 B vfo knob as well.

It DOES fit and many of us have matching vfo knobs on our K3's.

Oh I don't know about that. With my add on speaker system, and heavy knobs
I can close my eyes and then can't tell if I'm tuning my 9000D or my heavy
knobbed, external heavy dual speakered K3. Yes the heavy knobs add a nice
feel to the K3, if you've got $100 to spend on something frivolous, you
could easily do much worse...

I have set of the bronze knobs on my K3 #4165, and love them.

I have found two principal consequences of this knob change, and an
indirect benefit.

1 - The radio looks a heck of a lot better IMHO.

2 - The radio tunes much easier and has a more of a "quality" feel about
it, kind of like tuning a 75A4. I find that I use these knobs more and
my pan-adapter less for basic frequency control.

As a side benefit they seem to really irritate the Elecraft koolaid
drinkers on the list, whom I'm sure will explain in great detail why the
original knobs could not possibly be improved upon.

Heavy knobs Rock! You spin and it's inertia has you scanning - watching your P3 looking for blips. Treat yourself to a really good feeling.

Not here for a long time - just a good time.

Fwd: Weighted Tuning Knobs - Any Consequence?

In reply to this post by Jack Brabham KZ5A

Hi Jack- I have an old Icom 765 that I was all fired up to put an
inrad roofing filter into. The night before I was going to put it in I
had a terrible nightmare. I was buried by inrad roofing filters and a
man with a rubber duckie kept saying "It is blasphemous to alter
original equipment" I woke up in a cold sweat and never put the
filter in. My K3 will stay all original, thank you. 73's Skip KT9T

I picked up the weighted knobs for my K3 and K2 at Dayton and I absolutely love them. No issues here. Once you use them you won't go back IMHB.

Re: Weighted Tuning Knobs - Any Consequence?

In reply to this post by AC7AC

Ron,

Oh yes, that National knob (and gear reduction housing) was a great
one. I used it on several of my homebrew receivers - until the
Eddystone 100:1 gearing slide rule dial became available - that was a
great one too. I still have the Eddystone on my revision of the HBR-16
(mine was an HBR-18 with a Q multiplier at 85 kHz), and another that is
an incomplete chassis that was once destined to become a receiver (may
become one in time, but the probability is small). My National NC-5 is
unmodified, and although it sits in my attic, will never leave my hands
due to sentimental reasons.

But those were the days of yore where you had to have a calibration
chart to find the frequency that was represented on that National dial
(500 dial points), and the marks on the Eddystone slide rule dial had to
be inscribed on the dial face or deciphered from the fixed scale on the
slide rule.

In those "days of yore", we did not care about frequency readouts to the
nearest Hz (it was "cycles" back then), but only that one was operating
within the band for the emission type. Within those limits, those dials
worked very well and were comfortable to use.

We now have accurate digital frequency readouts, and the only remaining
discussion is how the knob "feels", "spins", "looks" and other such
factors. Our needs these days have changed dramatically.

I do worry about the long term durability of the encoders with quite
heavy knobs, although I have not seen a K2 or a K3 that showed signs of
encoder failure (yet). I had bought a couple of those old National
knobs and gear boxes that had a worn elliptical shaft from extensive use
and the dial would have "hard spots" in its rotation, so they were not
immune to problems either.

Re: "All original" K3

In reply to this post by William H. Droeger, Jr.

I have no particular inclination to spend $100 on a set of knobs, and I
suspect your blasphemous comment was tongue in cheek, but personally I
can't relate to that "all original" sentiment at all.

First off, the K3 has had several official hardware mods since its
original release and I bet it would be pretty darn difficult for anyone
to define just exactly what an "all original" K3 is.

Secondly, why would anyone willingly consign themselves to lesser
performance if better performance was easily available? Makes no sense
to me.

Thirdly, why distinguish between hardware and software on an SDR-type
rig? I'll bet you've changed firmware several times on your K3 since
you bought it.

I prefer to think of my K3 a tool, not an ornament.

Skip,

I wouldn't modify a pristine, old, collectible radio, but everything
else is fair game in my book. In fact, I probably get more enjoyment
out of modifying equipment than from using it.

Back in the 60's, when I was a Novice, we had a term for hams that
strictly used "as issued" equipment.... "Appliance Operator". I never
wanted to be accused of being one of those. My K3 was a "kit" an
remains unmodified only because I haven't identified any needed changes
that are within my capabilities.

Currently, I'm waiting on a shipment of parts from Mouser that will go
into a Heath HR10B RX that "should" make it actually usable for QSO's,
unlike the original which is almost useless. There is also a few mods
in queue for the associated DX60B and HG10B.

If that guy with the rubber ducky shows up again and offers you anything
to drink, don't drink it....

Weighted Tuning Knobs - Any Consequence?

In reply to this post by John Huggins, kx4o

I too believe the jury is still out concerning the long-term wear and tear
on the Elecraft encoders caused by the use of extra heavy knobs.

The original knobs spin just fine on my K3; besides I'm doing more
QSY's these days from the P3.
