Re: [Elecraft] Rework eliminators
I agree with what Elecraft say, Stan, and just follow the excellent assembly manual. You can't go wrong if you follow the instructions to the letter. Those so-called 'Rework eliminators' are quite expensive for what they are but would perhaps be useful for anyone building lots of K2 kits or do a lot of K2 servicing and fault finding. 73 de David G4DMP In a recent message, Stan AE7UT ae7...@gmail.com writes I'm just starting a K2 build and was thinking about using the rework eliminators.

Re: [Elecraft] Rework eliminators
Stan, If you install the rework eliminators, I strongly recommend you do *not* change the value of C71 nor install D19 and D20 until you are actually ready to install the real K60XV option. Those component changes will alter the VFO Range Select in a manner that cannot be properly tested until the K60XV is installed. The other Rework Eliminators do not cause problems of that nature. 73, Don W3FPR On 5/21/2013 1:54 AM, Stan AE7UT wrote: I'm just starting a K2 build and was thinking about using the rework eliminators.

What I do is install the option sockets and plug the components and jumpers that will be removed into the socket. You must be careful, then, that they do not fall out. This works for all options except the K60XV, which requires component substitution.

It's just that our Headers support all of the options. And perhaps more importantly, you won't run the risk of dissimilar metal corrosion on the internal socket contacts, or the risk of installing these parts in the wrong place. Also, note that if you follow the K2 manual exactly, you'll need to perform PCB rework to install the mating sockets for three of the options: KSB2; KAF2/KDSP2; and K60XV. (In total, five mating sockets are affected.) BTW, in addition to our Option Bypass Header kit and our Duplicate K2 PCB Parts kits, we also offer a second Rework Eliminator(TM) accessory; an Internal Mic Adaptor kit.

Re: [Elecraft] Rework eliminators
I've only built one K2, #5957. I installed the Rework Eliminators as I went along with the build, and there was no problem doing so. Subsequently, I installed all the on-board options for the K2. What with putting sub-assemblies in and taking them out for various reasons, I am very glad I had the RWE's there from the beginning. While not an expert on the K2 by any stretch of the imagination, I don't see how using them would compromise any aspect of the build and/or operation of the K2. Note, my unit is not equipped with the 60m option which may be an issue as noted elsewhere in this thread. I was and am very satisfied with them. ...robert On 5/21/2013 05:54, Stan AE7UT wrote: I'm just starting a K2 build and was thinking about using the rework eliminators.

RE: [Elecraft] Rework Eliminators
To Don and Ron and others: When I wrote my last post, I was unaware of Don's latest post giving some of the caveats with regard to the Rework eliminators. Certainly this is a very timely topic for me-- in the midst of my first K2 build, and following my latest goof (forgetting to install W6 and C6 on the RF board) that Don very kindly pointed out for me, just yesterday in fact! For the following reasons, my own K2 will incorporate only the rework eliminators (un-modules) for KDSP2 and K160RX: 1.) My rig will be CW only, without 60 meters. 2.) I have purchased (and will install at the first opportunity) the KDSP2 and K160RX modules. Installing the un-modules for these will make it easy to just plug in the selected modules when the time comes. 3.) I sailed past the opportunity to install the un-module for the KNB2 (which I also have purchased). 4.) Last (but not least) there seem to be no alignement issues associated with these particular un-modules. Thanks again for being here to help us out! One of the reasons I chose to purchase a K2 was the fact that there are approaching 6000 of these units in service, and there is this body of experience to draw from. 73, Chuck NI0C ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Rework Eliminators
Don wrote: ... the K2 manual tells you when to install the 'hooks' for these options. Fully populating the K2 with options following the K2 assembly manual, results in the need to remove 13 parts (seven jumper wires, three caps, and three resistors). In six cases other parts (three SIP connectors, one resistor, one cap, and one jumper wire) must be installed in place of the original parts which were removed. Given that soldering is the most common cause of problems, especially intermittent ones, we feel that the elimination of PCB rework is highly desirable. PCB rework is no big deal if you have the proper tools (solder wick should be avoided) and you are competent with them. Unfortunately, without both there is the all to likely possibility of lifting traces and/or blowing out plated through holes. (Please see our Builder Resources page for it's link to an excellent resource on PCB rework.) For the options you do not initially purchase with you K2, the alternative to our Duplicate K2 PCB Upgrade Parts kits is to disassemble the K2, in many cases fairly extensively, in order to add, remove, or rework the necessary K2 parts before installing the option. --- - - - --- For those of you who are brand new to soldering (or rusty after several decades), you won't find a less expensive place to start out than our header kit.

While supplies last, if you email Ken when you order our header kit and request one, he will gladly include (at no charge), one of our original rev. D boards along with the three resistors required to populate the UN-KNB2. --- - - - --- A few notes of caution for those of you considering making your own un- module devices from jumper wires ... 1) The silkscreen for W1 (adjacent to RF-J14) makes it appear that W1 goes between pins J14-1 and J14-6 but it doesn't! Installing it there by mistake would ground the antenna! Besides not being able to receive anything, grounding the antenna could result in blown PA transistors were you to attempt to transmit. 2) For those who don't initially purchase the Noise Blanker, or for those of you taking your time to build and install it, the use of a jumper wire (rather than the original 150 ohm 5 dB attenuator) to bypass it, is probably not a good long-term solution. 73, Happy Holidays, Happy Kit Building, Gary, KI4GGX, K2 #4067 http://www.unpcbs.com/ Rework Eliminator, Rework Eliminators, and unpcbs are trademarks of Ken Kaplan and Gary Hvizdak ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Rework Eliminators
Wow Don Ron, I'm shocked. Such heavy hitters coming down so hard against the Rework Eliminators (RE). As a novice builder, I built a bare-bones K2 with full RE. I spent the time going through the RE instructions and writing changes into the K2 manual prior to beginning the kit. Then I just followed the red-lined K2 manual for building and aligning. There were NO issues. Everything worked first time. No funny alignment stuff that I recall. Just smooth. Since then I've added the AF option. I unplugged the header board, plugged in the KAF2 and was up and running with no additional mods to the K2 boards. I recently swapped the AF for the DSP. Again, it was plug and play. Now I've removed the DSP and am again operating the rig with just the header board. Without the RE, what would I have done? First, I'd have to rework the K2 to add the parts for the KAF2. Then, after deciding I don't want to use either the KAF2 or the KDSP2, I'd have to either rework the board to remove the parts I added or I'd have to dangle a jumper wire across pins on the connectors. I don't like either of those approaches. The other approach is I just leave the KAF2 in there in bypass mode. This is what I suspect most K2 owners do. Buy an option, install it, never take it out. I also added the SSB option. For K2 mods, I had to rework two crystal grounding leads and had to put the shorting jumpers across the mic configuration header. That was it. KSB2 plugged in and is working fine. If I decide to be CW only, I can swap the SSB module for the header boards and I'm in business. I'm part way through the KPA100 build and so far, every single K2 mod that the manual has called for I've been able to skip since those steps were done during the initial K2 build. Certainly I don't have the experience or credibility of you two gentlemen, but I do have my own experience, and for me and my needs, as far as I can tell so far, the Rework Eliminators have been money very well spent. - Keith N1AS - - K2 5411.ssb - -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ron D'Eau Claire Sent: Thursday, November 30, 2006 2:12 AM To: elecraft@mailman.qth.net Subject: RE: [Elecraft] Rework Eliminators Anyone building a K2 with the rework eliminators should read carefully Don, W3FPR's warnings about how installing them will cause you to have to make extensive changes to some of the K2 test and alignment procedures.

The pin jumpers are available from places like All Electronics for 50 cents for a 40 pin header. Cut the header into appropriate lengths and solder jumper wires and caps/resistors across the correct pins. Put the jumpers for the each mod in a small envelope appropriately marked and ready for use if necessary. I can't see spending big bucks when $2 will do for something you will rarely use!!

-Original Message- From: wayne burdick - If the notion of plug-in substitutes for future options strongly appeals to you, and you don't mind *carefully* following the additional set of instructions that comes with them, then by all means consider this method. This is a KEY point. The Rework Eliminators present a sizeable documentation challenge. You'll spent significant time making hand edits to the K2 manual to put all the changes in. It took me something like 2-3 hours to mod my manual. Then, during building you have to follow the modified manual to a T. For me it was well worth it and went smooth as silk. If you try to merge the instructions on the fly while you build you're asking for issues. - If you'd prefer to minimize the amount of documentation you have to deal with in building a kit, then stick with the Elecraft manuals. If you're capable of building a K2, then you certainly won't have any trouble adding options our way. An advantage here is that you maintain full warranty support by staying within the Elecraft domain. Of course, you'll be reworking the K2 boards with each mod. It's not tough, but it is rework. I'd say if you're going this way, some rework tools may be in order. - Keith N1AS - - K2 5411.ssb - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

That was my point: to call such simple activities reworking is, to me, a huge overstatement. However, there are those who want to button up the rig once and avoid touching a soldering iron to the PCB ever again unless something fails, and there are those who have their rigs built and don't want to think about doing anything inside them involving more than plugging or unplugging a cable or module to make changes. Even fashioning a little jumper and pushing it into the proper holes in the connector if they decide to remove a module is more than they want to do. From the notes on the reflector I've read, the RE product is a great help for those owners; its success definitely suggests the RE product is appreciated by a significant number of owners. But the RE product is not a panacea. There are issues involved in buying and using them, especially if one does it as part of the original build depending upon the configuration of their rig. Don is the one who can advise about those in detail. Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] Rework Eliminators: when to use them, and why
The pin jumpers are available from places like All Electronics for 50 cents for a 40 pin header. Cut the header into appropriate lengths and solder jumper wires and caps/resistors across the correct pins. Put the jumpers for the each mod in a small envelope appropriately marked and ready for use if necessary. I can't see spending big bucks when $2 will do for something you will rarely use!! It really is that easy. I just opened my K2 up for the first time in a year or so to install the 160m option. It took almost no time to build the 160m board (about ten parts) but it took quite a while to remove the top and bottom covers (being careful not to lose the mounting hardware for the finals, which I didn't realize until little screws and washers started falling out all over the place), remove a jumper, check the value of two caps (didn't have to change those), install three more caps, install the header, install the receive antenna connector, install the board, and solder the jumpers to the receive antenna. Then I had to replace the bottom cover, being careful to get the heat sink mounting hardware correct again (non-trivial and required digging out the K2 construction manual and reviewing the instructions for mounting the finals, which is spread over two or three sections of the text) and replace the top cover. I own the Rework Eliminators but by the time they came out I was down to just a couple options left to install so I've never bothered to install the RE boards. However, I can definitely see the value of doing the RE installation while building a new K2. Even if you install all the options shortly after building the K2, there is a lot of detailed disassembly required. The longer you wait the more you forget about how things go together, making it more difficult to efficiently disassemble the radio. For many of us, removing components is a real PITA. I was fortunate to stumble onto a good price for a desoldering station and it has been worth every penny even for just the dozen or so times I've had to use it while building a K2 and KX1. Your argument is sound, but it doesn't cover all the bases. First, you're right that the DIY price may be only a few dollars. But you assume that all of us have a deep junk drawer with all the random caps and resistors that are required. You also assume that we're all clever enough (or have enough time) to figure out what to jumper and where to add a cap to create our own replacement modules. Your argument that the RE modules are big bucks misses the fact that less than $40 to buy a complete set of RE headers and parts is pretty miniscule compared to $1800 for a fully-loaded K2/100. (And $1800 for a fully loaded K2/100 is pretty miniscule compared to the competition.) My point isn't so much that you're wrong, but rather that this isn't as cut-and-dried as you seem to indicate. I agree that upgrading the K2 isn't a huge problem, but there are many complicating factors that can make it difficult enough that spending $40 up front isn't a bad idea. It's neither expensive nor complicated. Craig NZ0R K2/100 #4941 K1 #1966 KX1 #1499 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Rework Eliminators
-Original Message- From: Ron D'Eau Claire I surprised that you'd consider my recommendation to read Don's comments as coming down hard on the RE product. Don spends a lot of time working with builders here on the reflector who have problems and I've noticed that a number of those problems are, as he says, based on someone using the RE product without realizing how they can change the test and alignment process. -- IIRC, Don called the rework eliminators a waste of money for most K2 builders. He also said the alignment procedures change if you use them. You're recommendation to read Don's post was a sort of endorsement of what Don said so that's how you got drug into this :-) I thought his comments were pretty solidly based on facts and expressed fairly. I've worked with Don on many projects and learned to trust in his expertise. --- Yes, Don is great, solid, factual. I agree. That is why it was so shocking to me to see him speak strongly against something that in my experience very positive. If it was just about any other person on the list, we could just dismiss the comments meaningless, but this is Don we're talking about. And then Ron (another very knowledgeable, trustworthy contributor) backs them up. Wow. -- However, there are those who want to button up the rig once and avoid touching a soldering iron to the PCB ever again unless something fails, and there are those who have their rigs built and don't want to think about doing anything inside them involving more than plugging or unplugging a cable or module to make changes. Even fashioning a little jumper and pushing it into the proper holes in the connector if they decide to remove a module is more than they want to do. -- Yep, I guess that's pretty much where I am. Jumpers pushed into little holes, or caps with their leads pushed into little holes doesn't sound like how I want my K2 to be in the long run. That's a temporary patch for troubleshooting, not a long term bypass. The RE header boards are a far better long-term solution to plugging the headers. Sure, one could build up a more robust header plug but if you don't really want to be touching the soldering iron once the rig is done, then you don't want to have to run to the store (if you have one nearby) to get the parts to build the plug. - But the RE product is not a panacea. There are issues involved in buying and using them, especially if one does it as part of the original build depending upon the configuration of their rig. -- Panacea, it is not. There are pros and cons and each person will need to weigh the pros / cons for their particular situation. The RE could be a waste of money or a God-send, depending on who you are and your situation. 73! - Keith N1AS - - K2 5411.ssb - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Rework Eliminators
Folks, IM(not so)HO, Rework eliminators are fine for those options that you DO NOT intend to install initially (except for the K60XV). For those options that you order with your K2, the parts to install these options are included with the option kits and the K2 manual tells you when to install the 'hooks' for these options. Your ability to test the K2 according to the manual instructions is compromised with the Rework Eliminators because you must coordinate two sets of instructions to get the task accomplished. The easy and safe path is to simply follow the K2 manual instructions without installing the Rework Eliminators. The K60XV option is a bit on the 'strange side'. If you install the parts for the K60XV option according to the Rework Eliminator instructions (especially the change on C71 and the addition of D19 and D20), the entire character of the K2 VFO circuit changes. The VFO voltages measured at R30 will change, and since the K2 cannot be tuned to 5300 kHz from the 60 meter band until the K60XV is actually installed, you end up with a K2 that cannot be fully aligned in a proper manner - and you must re-visit the alignment when the K60XV is actually available (so much for the 'plug and play' ads). For problem 'chasing' on options that you have purchased with the K2, there are easy to implement jumpers that can be placed into the option headers with a couple capacitors and a few jumper wires (the Rework Eliminator boards are too large IMHO to allow complete access to all probing points in the K2). Specifically the KDSP2 can be substituted with 2 jumpers that take the place of the R18 and R19 zero ohm 'resistors'. The KSB2 requires 2 wire jumpers in place of W2 and W3 and one .001 uF capacitor in place of C167 stuck into the KSB2 headers. The KNB2 is the one exception, because a proper termination requires a 6 dB pad to be installed at the header. Yes, a simple wire jumper in place of W5 will substitute for the 6 dB pad in most cases, but the termination for the Post-Mixer Amplifier will not be quite correct and the receiver IMD will suffer a bit, but for most testing purposes, a straight jumper will do the job fine - just do not attempt IMD measurements without the proper 6 dB pad. All in all, I regard the Rework Eliminators as a waste of money and an inconvenience for most builders. As I said, the K60XV rework eliminator inclusion can lead to a number of problems and I trust that those problems with the K60XV are now identified in the documentation with the Rework Eliminator instructions - I have had correspondence with the Rework Eliminator folks on this subject, and they did say they would address the situation, but I have no information on the outcome of those discussions. 73, Don W3FPR -Original Message- Also, if I bought the DSP filter and intend to install it, is the rework elimnator still useful for using the rig without the DSP, or if I want to install my own filter in place of the DSP filter? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Rework Eliminators
Anyone building a K2 with the rework eliminators should read carefully Don, W3FPR's warnings about how installing them will cause you to have to make extensive changes to some of the K2 test and alignment procedures. If you want to remove a module at some point it's dirt simple without the rework eliminators. It involves fashioning a jumper or two out of some old clipped resistor leads to fit in the open connectors left when you pull the module. In one or two cases, the jumper is made with a supplied fixed capacitor. My S/N 1289 built in 2000 has been torn down and rebuilt so often I've lost count. It's been a test bed for a number of the K2 mods and improvements over the years.

The un-module manual say don't install C167 and install a jumper at J11. I'm inclined to believe that it is saying to install a jumper instead of C-167. Is this correct.

RE: [Elecraft] Rework Eliminators? OK?
- Ron said: Having read many, many posts on this subject, I'm coming to the conclusion that it's like asking whether someone likes chocolate or vanilla ice cream best. *snip* You will have to decide whether pulling a panel to install a module is worth adding the rework eliminators. It isn't for me. It definitely is for others. P.S. I prefer chocolate ice cream, if that's any help G. --- True enough, Ron. IMHO Elecraft should have made the K2 plug play rig from the start. It would have increased the cost of the basic unit, but not by much judging from the small number of parts and the simplicity of the module header boards. But, as you say, the actual effort of making the mods is small and for someone who is a builder at heart, the effort is not really a drawback. I really like the fact my K2 is fully plug play. I can add or remove options at will. I'll put in what I think makes the rig the best. If I ever sell it (I sell everything) the new owner may want a different set of options and the rework eliminators makes that simple for them. I believe resale value of my rig is higher with them there than not. Fortunately for both of us, the rework eliminators are available. I can have my plug play rig and you can have the rig at a lower cost. ...

[Elecraft] Rework Eliminators? OK?
I'm 40/100 thru my K2 #5422 kit. I'm wondering what plus minus the Rework Eliminators would buy me? Do all these extra pcb's, jacks, plugs and add-ons cause any RF or comm problems to the K2? Potential strays and parasitic R/L/C's could be a factor - I wonder? Will there be major take-apart work for me, when I go back and decide to add SSB, NOISE BLANKER and DSP? Elecraft K2 notes don't seem to indicate this. If I decide to sell a perfectly aligned basic K2 - and build another, would adding Rework Eliminators add or take away from the K2?

[Elecraft] Rework Eliminators
Another advantage is if you buy an option like KSB or one of the filters and decide it isn't what you want, just unplug it, install the bypass header, and sell it.

Elecraft K2 notes don't seem to indicate this. If I decide to sell a perfectly aligned basic K2 - and build another, would adding Rework Eliminators add or take away from the K2? - Having read many, many posts on this subject, I'm coming to the conclusion that it's like asking whether someone likes chocolate or vanilla ice cream best. I built my K2/100 six years ago. It's been apart probably in excess of 100 times. If I built a new K2 today, I'd not use them. That's because I haven't found it at all a nuisance to install modules as I went along, including the connectors. For those modules that I didn't use, there are jumpers soldered in place to bypass them so there's nothing to come loose. Others find it a pain to pull a panel. I found that one of the very nice features of the K2: one can get inside in a flash with little effort or bother. That's why I wouldn't bother. I can remove the most difficult panel, the rear bottom plate that serves as the 10 watt final heat sink, in less than a minute and put it back in the same length of time. It's simple to keep the heat sink hardware in place: just don't let the screws fall out and put the nuts back on while the cover is off. Others wince at the idea of pulling any cover off, so anything that avoids that is helpful. For them the rework eliminators seem to be just the ticket! So what it comes down to is this: Others will have to speak to any electrical issues with the devices. You will have to decide whether pulling a panel to install a module is worth adding the rework eliminators. It isn't for me. It definitely is for others. P.S. I prefer chocolate ice cream, if that's any help G. Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Rework Eliminators
Had these been available when I built my K2, I would be more enthusiastic about adding options. The one feature of the K2 I don't care for is the heat sink and mounting of the final transistors. I don't relish the thought of taking the heat sink on and off and messing with those little washers and pads to add each option. If I were to build another one with the thought of adding options, I would definitely consider the rework eliminators. 73, Dave N7AF - Original Message - From: Charlie, W0YG [EMAIL PROTECTED] To: Elecraft Reflector elecraft@mailman.qth.net Sent: Wednesday, March 22, 2006 8:30 AM Subject: Re: [Elecraft] Rework Eliminators Mike, AI4NS, wrote: I ordered the complete kit for the partially assembled K2 I just bought.

[Elecraft] Rework Eliminators
Hello List: I just finished building K2 SN 5380, with no options, for a gentleman in Virginia and he chose to have me install the Rework Eliminators. This is the first of these I have installed and it sure is a nice feature and well worth the investment. Now the addition of any options will only require to removal the Unmodule and plug in the new option since all the connectors and components are already in place No more tearing the K2 apart to install the options. This is really important when it comes to removing and replacing the final transistors heat sink. Additionally I have purchased a set of the Unmodules for myself and when I get a K2 for repair I remove the options and install the unmodules and then make sure the K2 is working properly as a basic transceiver and then it is easy to add back on option at a time. This sure helps in locating problems in a transceiver. I strongly recommend the use of these after market products if you plan to add options to your K2 in the future. 73 Jim Younce K4ZM K2 SN: 18 K2 Field Tester ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Rework Eliminators(TM) Companion Guide - Official Release
Our new 35 page Rework Eliminators(TM) Companion Guide describes how to build a rework-free plug play ready K2. The procedure incorporates un-module (option bypass) headers plus all of the PCB mounted parts that are missing from a stock ($599) K2. It combines the initial K2 assembly procedure and all of the K2 option preparation steps, into a single seamless process. This eliminates the need for any subsequent disassembly or PCB rework to fully outfit a bare K2 with options. This procedure is ideally suited to builders-for-hire as you can now offer your customers an easily upgradeable bare radio. The first half of the guide is an introductory tutorial suitable for someone who is still just contemplating their first K2 purchase. It includes instructions for determining which if any additional parts kits you will need to purchase. The actual alternate assembly instructions comprise the second half of the guide. Please visit our website for the PDF. Due to our long URLs, its best if you use the ***Documentation Downloads*** link on our Resources directory page http://home.cfl.rr.com/garyhvizdak/KI4GGX/unpcbs/Resources/ to get to the PDF. 73, Gary, KI4GGX K2 #4067 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Rework Eliminators Unmodules
I am building K2 #4766 slow and easy. I am putting all the Unmodules as I go. The Unmodules' instructions leave little chance for error and look very professional on the RF board. The quality of the boards, parts and instructions is outstanding!! I suggest all builders install the Unmodules because it will eliminate a lot additional work troubleshooting modules. I have no relationship with the Rework Eliminators Unmodules group and do not expect or want compensation. Thanks Ken and Gary for a fine product!

[Elecraft] Rework Eliminators
Elegance. Excellence. Usefulness. These three qualities are of paramount importance to me: Elegance of product design, excellence in product execution, and overall product usefulness while meeting key objectives. In large part, these hallmark qualities are what has set Elecraft apart from myriad other manufacturers. Indeed, they have raised the bar for manufacturers, and for our expectations of them. When I find something good, I want to mention it in mention in passing. When I find something GREAT, I want to shout it from the rooftop. I'm shouting here! Rework Eliminators are not an Elecraft product, but they easily could be! Offered by Gary (KI4GGX) and Ken (WB2ART), these un-module headers are a logical follow-on accessory for anyone who has (or will have) a K2. Elegance, excellence and usefulness ... sound familiar? Rework Eliminators meet the Elecraft high standards in every way. And let's face it, we're awfully picky about what goes into our K2. Gary and Ken have resolved the problem of being able to temporarily remove specific installed K2 options, returning the K2 to its virgin state at will, without compromising the electrical or aesthetic integrity of the K2s pcbs due to reworking (i.e., de-soldering and re-soldering). Their design is truly elegant in its simplicity, superbly executed with very high quality pcbs and assembly user's guide, with usefulness that will last for the life of your K2. For 20 bucks ($8 - $20, depending upon which flavor kit you purchase), you simply can't go wrong. It's a no-brainer! Long before the Rework Eliminators came to fruition, I had the opportunity to chat with Gary via email as this project was developing in his head. In a sense, I've watched Rework Eliminators grow up. More importantly, I had ample opportunity to watch Gary and Ken agonize over the smallest details, wanting this to be a no compromise K2 add-on that anyone would be proud to own while maintaining the Elecraft standard that we've all come to expect and respect. In fact, I was so inspired by their attention to detail and quality, I offered to help proof-read the final versions of the User's Guide. Mine was a small contribution, but a proud one nevertheless. So this is my disclaimer: yes, I was a proof-reader, but I was also one of the few who pre-ordered and paid long before the first kit shipped. I believed in the project (and them) before the kits existed. Now, with the Rework Eliminators in my K2, my delight and respect was never misplaced!
