Re: [Elecraft_K3] K3 Shipping Status Update

Ron Durie
 

Eric and Wayne,

 

I have a suggestion about the PCB headers.  It would be nice if you could send with each new K3 kit a small tube of Caig.  www.caig.com  

 

I recommend treating each PCB header pin with Caig >> “DeoxIT” >>  in the K3 build. 

 

This will keep contact resistance low; lubricate the pins; and most importantly prevent Oxidation. 

 

I have found over the years that Caig products are the best at what they do, in the market place. 

 

I plan to do this on my K3 build.   J    Thank you.

Subject: [Elecraft_K3] K3 Shipping Status Update

 

Our field testers are a very diligent and experienced bunch. They've
been working hard (on your behalf, as well as theirs) to exercise
every possible K3 feature and uncover opportunities for refinement.

The firmware development team (Wayne, N6KR, and Lyle, KK7P) has been
putting in very long hours to keep up, and we've made some minor
component changes as well. As a result, important features like FSK
mode, text decode/display, flexible VOX control, KRC2 support and many
others are being optimized under real-world conditions. We've also
verified our performance on multiple K3s both in the lab and on the
air. The field testers have really pounded on the user interface, and
the tweaking we've done has made the radio both easier to use and more
versatile.

The same engineers who are doing firmware and hardware development are
also heavily involved in completing the user documentation. This is
why we haven't been able to release a draft owner's manual or assembly
manual. We've got a lot of catching up to do on these tasks, so we're
revising our target shipping date for the first K3 production run to
start at the end of August.

K3 materials purchasing and manufacturing is well underway and our
staff has been working hard to make sure all of the key K3 components
arrive in Aptos at the right time. This is a tremendous task, as you
might imagine, and they have done an excellent job hunting down every
problem supplier and component. Our production staff will use the
extra time to build inventory and refine our automated K3 testing.
This will allow us to minimize any delay to the second and later
production runs. Our goal is to ship a stable, and high quality,
product starting with the first one out the door. We think you will be
pleased with our results.

We appreciate your patience as we transition into full K3 production.
We'll keep you informed of our progress, and look forward to your
feedback on the manuals as they near completion. We've already had
many offers to proofread -- thanks!

For plated connectors, you may want to use Caig's ProGold instead of Caig's DeoxIT.

I think we were aware that this was likely to happen...
and, in spite of my earlier "grousing"... I am more than willing to
wait a while longer while the K3 is tweaked and furtehr refined.

Hat's off to Wayne and Eric.. the rest of the gang AND, of course,
the Beta testers...

News of the slip in the time line really is appreciate, Thanks for
keeping us up-to-date with the latest developments.

Like my grandfather used to say... "The best things in life are worth
waiting for." Of course,.. he was also fond of saying, "Never fry

Thanks for the suggestion Paul.  Actually I do use ProGold on all plated connectors.

Paul, this looks like a good idea and the products certainly look like they
will be useful. Could you recommend any particular item on this site - the
spray?
The pens?
Would normal and gold be useful or is just one type sufficient
Any comment would be helpful since I'll buy a few things, taking advantage
of one postage cost and the current exchange rate.

I like the little bottle of ProGold with the brush in the cap, for wiping pins in connectors.

I also like the felt tip (chisel tip) pen for wiping flat contacts on PC Boards.

For large quanties of PC Boards, of course you'd use their ProGold cloths.

I have spray bottles, but they get the ProGold everywhere so I don't use them too much.

Also get some DeoxIT for unplated connectors.

I also like their Moving Contact Lubricant for getting rid of the scratchiness in pots.

This is why.......

Bill Kitchin
 

In am going to buy the K3. I LOVE QRP and SIX METERS. I also like to
buy American Made items. The K3 seems as though it was designed for
ME. I like the fact that get e-mails from this group from the dudes
that designed the thing AND they speak fluent English. Can
t get any better than that!!

Caig De-oxit products.

JACrux <jacrux@...>
 

Thanks for the tips about Caig products.
But some recent reports suggest that a bit of corrosion may be trivial
compared to the long term effects of lead-free solder and the tin whisker
growth that can destroy useful equipment. It is interesting that
military/medical equipment is apparently exempt from the lead-free
requirement ..... because tin whisker damage is unacceptable.
Time for the K3 to be designated strictly MIL-SPEC, or does it escape the ban
because it is a "kit" --- as do the other kits ?

Re: [Elecraft_K3] Caig De-oxit products.

ajsoenke@...
 

In any event,  I doubt that the tin whisker issue would be a problem with this application. It is primarily an issue in gravity free environments and certain types of hermetically sealed and evacuated packaging used in aerospace applications.

8-band graphiq equalizer

rdehli <rodehli@...>
 

Hi.

I am very curious on how the K3's 8-band graphiq equalizer will
function. This is a very nice feature to have built-in to the rig. As
I understand, it will have separate settings for RX and TX. The
center frequencies for the 8 bands are 200Hz, 400Hz, 600Hz, 800Hz,
1200Hz, 1600Hz, 2400Hz and 3200 Hz. Only thing is that it might would
be good to have a 100Hz adjustment also, but only time will tell if
this is needed. Let's say you set up a transmitter bandwidth of 3,5 -
4kHz and use a good desktop microphone, I will assume you can get an
extremely good TX audio from this rig. I have found the Yaesu MD-100
to be an excellent microphone, it goes from around 100 Hz - 5kHz and
has a nice 10dB increase in audio between 2000-3000Hz. Perfect for
SSB, it has a bit more low end than a hand mic without being
to "bassy". It is easily rewired for the K3. I'm not shure what
voltage the K3 has on the mic connector, the MD-100 uses +5V which
will enable the low-cut filters and "high emphasis" function
underneath the MD-100. But you probably won't need those filters, so
one can just cut away that wire inside the MD-100 mic connector. I
have the W2IHY 8-band equalizer, and the center frequencies on this
one is 50Hz, 100Hz, 200Hz, 400Hz, 800Hz, 1600Hz, 2400Hz and 3200Hz. I
find this one to be perfect. In my case (with the MD-100)and the
Yaesu FT-2000 I have adjusted the 50Hz at +16dB, the 100Hz is at
+6dB, 200Hz 400Hz and 800Hz are left in "center" position (flat),
+3dB on the 1600Hz, +8dB on the 2400Hz and +12dB on the 3200Hz. My
audio reports have been "extremely good" in all cases with this
setting. If one wants a bit sharper audio for DX one can just reduce
the 50Hz and 100Hz to minus 16dB, that's all. If one uses a
microphone with a much wider frequency span (like a studio mic) one
must be careful with increasing the 50Hz and 100Hz settings, to much
increase here will make you too "bassy" and will ruin your audio. Use
HIFI-headphones with wide audio span (I use the AKG HSD-271 headset)
and use the monitor function to listen to your own audio when
adjusting. This is an easy way of "tailoring" your TX audio to the
level YOU want. Good luck !

K3 vs Orion II

James A Denneny Jr <denneny@...>
 

I just joined this reflector and have an order for the K3. I own a TT
Orion II and have been very pleased with its performance. I will be
watching for objective data between now and October to see how K3
stacks up against Orion to decide if I want to take delivery on the K3
and sell the Orion. I am hoping to see some more published data from
Bob Sherwood and/or ARRL before my order is ready.

I think that QST typically takes 4-6 months after a product is released to
publish a review, so unless Elecraft gets some unusual fast publicity out of the
ARRL, your rig will be ready before they are.

The two rigs share nearly an identical front-end, with narrow filters
at 9 MHz for Orion and 8.2 MHz for the K3, so RF performance should be
nearly identical. I believe the main differentiators in favor of K3 are:

1. Price
2. High performance Sub RX (unlike Orion's) allowing true
phase-locked diversity (unlike Orion).
3. Ergonomics

Time will tell but I've sold my Orion and ordered a K3.
