K-2 100 Tuner question

Johnny Matlock
I am looking at a K2-100 that is has the amp mounted in the top cover.

Is it possible to have the 20 watt internal tuner in this enclosure
With the amp?

Thanks

Happy Holidays

No. It is one or the other. The external 1/2 height KAT100 can be used with
the k2/100 though.

Johnny,

NO!  First of all, the KPA100 occupies the entire top area of the K2
(there is no room in the K2 for both) and secondly, the KAT2 is only
rated for 20 watts,
and thirdly, the ATU must be between the amplifier and the antenna - a
tuner at the input of an amplifier will do nothing useful.

Use the KAT100-1 - it is about half the height of the K2 enclosure.

Contrary to some comments I have seen and heard, the KAT100-1 is
available and will be for some time in the future.

It is the EC2 enclosure that is no longer available, and the KAT100-2
depended on the EC2 for the enclosure, so the KAT100-2 had to be
discontinued at the same time as the EC2 was discontinued.

I always wondered why Elecraft discontinued the EC2 enclosure. Even the mod to use the EC2 enclosure with the 100 watt amp and tuner was unofficial as I understood. I built the 100 amp and tuner in the EC2 as per the instructions to mate with the K2. Maybe the demand was not there but neat setup and works great!

Re: K2 100 Tuner question

Doug Person-5
As I dug around in my store room to recover the KTA100-2, which sold
quickly, I also found, still in the brown paper, an original K2 QRP top
cover. I believe this was left over from K2 build that went directly to
the 100 watt amp option.  Sop if anyone needs a new top cover, contact
me off list.

K-2 100 Tuner Question

Edward A. Dauer
In reply to this post by Johnny Matlock
 Nope.  But there is another option.

I have three K2s in various configurations, just because I love building them.  One has the amp and the tuner in the now unavailable EC2 in the "twins" configuration.  Another has the amp inside the K2 and the tuner in the half-height chassis sitting on top.    I almost never use the twins.  The K2/100 and KAT100-1 mate beautifully -- electrically, physically, and aesthetically -- a very neat system with less cabling lying around than the twins require and only half the footprint on the desk.  And the KAT100-1 works fine with the K2 at QRP power.  No need for the internal tuner.  I have that in the third of my three -- also seldom used.

Thanks for the replies and all of the ideas of how to configure the k-2
with various tuner/amp set ups.

In reply to this post by Doug Person-5
All,

Once again, the EC2 was discontinued because the metal supplier is no
longer in business.
To find another vendor is out of the question.  The startup and tooling
costs would be excessively high for the projected quantities involved.
How many EC2 enclosure could Elecraft sell at a price point of $250 or
more per unit (my guess, not anything official from Elecraft)?
It was not a high sales volume unit where such startup and tooling costs
could be swamped out by the sales volumes.

Re: K2 100 Tuner question

Don Wilhelm
Josh,

The stuff needed to punch the panels out of a piece of aluminum and put
the holes in the right place.  The tools needed to bend the panels at
the right places.  That stuff can cost thousands of dollars.
It is not the same as making a one-off copy using hand marked pieces.

If you have ever studied what it takes to make production quantities of
a device, then you would understand that it takes specialized tools that
can be quite costly.

In my small custom woodworking shop we usually went the inexpensive way
by making jigs and other pattern tools, but doing even that costs money.

Re: K2 100 Tuner question

Gary-5
Or if someone would publish the files required for 3D printing...

Then the builder can opt print his own or not. The costs are shifted to a spread out model.  Finding someone to print something for a reasonable fee is becoming relatively easy.

Re: K2 100 Tuner question

Hi Don,

Sounds like you're not up to speed on 21st century sheet metal fabrication.

Small volume parts like this would be cut on a laser and bent with a CNC press brake. The only setup is loading the programs and there is no tooling. If someone draws the parts using a CAD program like Solid Edge, the resulting 3D models can be utilized directly by the vendor. Even small job shops have laser cutting ability, especially for small gauge material like this.

Hard tooling would only be used in high volume (thousands at least) for a very cost sensitive project.

I'm not familiar with methods prior to the '80s, but even back then this would be done on a turret punch press. You'd only need tools for oddball shapes the vendor didn't have, and those are fairly inexpensive. For small runs you'd have the setup time of loading tools into the turret, but as noted, that no longer exists.

73,
Josh W6XU

Re: K2 100 Tuner question

Don Wilhelm
Josh,

I may not be up to speed, but there are startup costs for anything. 
Those costs have to be added to the product cost and for small volumes,
it can be prohibited.
Entering a CAD file, getting scheduling from a small shop that may have
a full schedule already can be costly.

Re: K2 100 Tuner question

Josh Fiden
Oh come on. Now you're just making things up.

I just had some structural brackets made. They had 18 holes, laser cut and bent from 3/8" thick 304 stainless. They were $45 ea for 13 pcs. Supplier did the CAD for me from my pencil sketch. Took him less than 10 minutes, no extra charge.

A little difficult to extrapolate from that example, other than to note the very low volume, it's expensive material and slow to cut.

You can buy a 3D printer for under $5K and make metal work on an as needed basis. That is where the auto industry is going.

Re: K2 100 Tuner question

Well, if you spread $5K over a projected sales quantity of 100 (there
were not of EC2 enclosures sold), then you have a tooling cost of $50
per enclosure.
Add to that the cost of administrative support, creating web pages,
packing and shipping labor, and you have an EC2 enclosure that has to
sell for over $150 to produce any profit.  About double the original
customer cost of the EC2.

It is different if you can project selling thousands of the items.
Enough said.

Well no. That $5k could be spread over all the metalwork and greatly reduce inventory.

To the original point, there is no difficulty finding a different vendor, there are no tooling costs, and producing parts in small quantity is not cost prohibitive.

Some people need to be right. Others want the right answer. Only the latter is of interest.

Enough said.

Re: K2 100 Tuner question

Edward R Cole
In reply to this post by Don Wilhelm
Have to agree, in principle, with Don.

Many of you may never had done a small volume production.  I have.
I cannot afford to purchase CNC tooling, metal brakes, etc. for a
project of twelve copies.  Vendors are all out of state with added
shipping costs.

So I chose a good quality commercial chassis from Hammond and built
an aluminum jig to hold it in a vise for drilling.  Square holes
required hand filing.  Stick-on labeling.  I used a pcb made by a
reputable small production house (W6PQL).  Those that bought the 80w
2m amp got a pretty good product but no confusion that it was hand
made.  Costs were hard to get competitive with commercial amp mfrs
but I think the reliability might have been better.

You would have to survey my customers who all read this list and most
have Elecraft radios that were used with the amp (majority had the KX3-2M).

I had an opportunity to buy out a popular line of transverters and
recently a popular preamp maker.  Cost/labor time were decisive
against them (mostly at my age).  Had a hard time convincing my self
that working for under $10/hour was a good deal.  Each amp took about
18 hours each  and my net was under $100.  So I considered it
learning experience and labor of "love".

In manufacturing there is a concept called "economy of scale" which
Wayne and Eric are probably very conversant.
