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?

No. It is one or the other. The external 1/2 height KAT100 can be used with
the k2/100 though. 73, Byron N6NUL On Sat, Dec 22, 2018 at 11:51 AM Johnny Matlock <[hidden email]> wrote: > 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? > -- - Northern California Contest Club - CU in the Cal QSO Party 5-6 Oct 2019 - www.cqp.org ______________________________________________________________ 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] |

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. 73, Don W3FPR On 12/22/2018 2:49 PM, Johnny Matlock wrote: > 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? > ______________________________________________________________ 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] |

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!

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. 73, Doug --KJ0F On 12/22/2018 2:30 PM, Rick Wheeler wrote: > I always wondered why Elecraft discontinued the EC2 enclosure.

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.

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. 73, Don W3FPR On 12/22/2018 4:44 PM, Doug Person wrote: > > On 12/22/2018 2:30 PM, Rick Wheeler wrote: >> I always wondered why Elecraft discontinued the EC2 enclosure.

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. 73, Don W3FPR On 12/22/2018 7:35 PM, Josh Fiden wrote: > What tooling? > > 73 > Josh W6XU > > Sent from my mobile device > >> On Dec 22, 2018, at 3:11 PM, Don Wilhelm <[hidden email]> wrote: >> >> 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.

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.

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 Sent from my mobile device > On Dec 22, 2018, at 5:15 PM, Don Wilhelm <[hidden email]> wrote: > > Josh, > > The stuff needed to punch the panels out of a piece of aluminum and put the holes in the right place.

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. 73, Don W3FPR On 12/22/2018 9:16 PM, Josh Fiden wrote: > 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.

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. 73 Josh W6XU Sent from my mobile device > On Dec 22, 2018, at 7:03 PM, Don Wilhelm <[hidden email]> wrote: > > Josh, > > I may not be up to speed, but there are startup costs for anything.

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.

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. 73, Don W3FPR On 12/22/2018 10:38 PM, W2xj wrote: > You can buy a 3D printer for under $5K and make metal work on an as needed basis.

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. 73, Josh W6XU Sent from my mobile device > On Dec 22, 2018, at 8:11 PM, Don Wilhelm <[hidden email]> wrote: > > 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.

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. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: [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] |
