“… a great bit of engineering; … neat design …”
“… ingenious, it neatly solves a difficult problem, … and the documentation … is superb - clearly written with excellent diagrams. … an elegant solution …”
“It works slick … very clever engineering …”
“… a great product …”
“… your very cool microphone configuration board pushed me over the edge to outfit the new K2 with phone.”
“… Elecraft should incorporate your design … Assembly of the IMA was quick and easy. The circuit board and parts are of high quality … My [previous] remarks … stand. If anything, I’m more enthusiastic. … when I was finishing up, to say I was “relieved” that I was just moving around jumpers and not soldering anything doesn’t even come close to covering it! Thanks again for a great product …”
“… The product quality is excellent. … I can now change mics in minutes …”
“… works great … Nice design.”
“I’d give you and Ken an "A" for a really cool little add-on to the K2. I used … a manual wirewrap tool to initially wire my mic jumper block, and it was a real pain …”
“… excellent documentation …”
“Once the IMA was plugged in it took less than 5 minutes to convert from one mic to another – now that’s sweet …”
“… that Internal Mic Adapter made it a dream building [my latest] K2.
“… the documentation is excellent … A great addition to any K2 …”
“… very clever … I can’t think of any other radio that can be configured for just about any microphone … in two minutes flat …”
“The IMA installed quickly and smoothly. … Count me a satisfied customer.”
“… clear instructions …”
“… a useful, high quality addition …”
“You have a great product that solves a real problem.”
“My K2 is much better off because of your products …”

“… I loved the idea …”
“… I’m more than happy not to take the K2 apart again for rework related to every module … It’s a great thing not requiring any disassembling when installing the options …”
“Congratulations on the design and first quality printed boards, I wish I had them when I made my K2 …”
“… an excellent kit, very clear and easy to complete … you guys have done a really professional job in making this very useful kit …”
“Thank you for the excellent service.”
“… it is invaluable to figuring out how the modules relate to the main schematic.” [RE: our color-coded un-module diagram]
“There’s nothing to compare with the convenience …”
“My K2 is fully loaded, but there are times I want to play around and your Un-PCBs ensure I don’t have to … poke tinned leads into gold plated socketry …”
“Un-PCBs are an invaluable tool …”
“… good idea … very useful … high quality …”
“I knew there was a better way of [..] building a vanilla K2 … Adding unpcbs to my second K2 has saved me time …”
“The [new rev. G] boards look very impressive!”
“Thanks for a beautifully put together and ingenious project.”
“My first task … is to remove the KNB2 and mess with the capacitor values to try and reduce the racket from the latest Pendolino trains we have running here. At least I’ll still be able to operate … if the job takes longer than expected!”
“… everything worked as indicated … no rework has to be done and every option plugs in and works …”
“… I was amazed at the outstanding quality … The printed circuit boards are fantastic … it beats me how they do it for the price.” [RE: our rev. G headers circuit board]
“It was after I received the header kit, I got inspiration to repair my K2, which had problem in T6 (preamp transformer). The Unmodules really helped in testing, because there was no need to reinstall removed options.”
“I installed each option into the K2 in less than 5 minutes! No need to remove the heatsink, or add/remove jumpers and components … just unplug the rework eliminator and replace it with your option. … I’m glad I used this approach.”
“You’ve designed a fine product and implemented it very well.”
“I wince every time I unsolder something from my K2. Your kit is worth much more to me than you’re charging for it.”
“… rework eliminators provide advantages for all K2 owners …”
“… disassembly … is minimized … Rework Eliminators helped me get … on the air …”
“… your products … [will] save me from unnecessary disassembly and wear and tear on my new K2.”
“… Rework Eliminators … were a great help …”
“Thanks for your service …”
“Thanks … for an excellent product.” [RE: our rev. G headers circuit board]
“I can definitely see the value of doing the RE installation while building a new K2.”
“Thanks for following the Elecraft tradition of excellent customer service!”
“You guys have done an exceptional job on this accessory … it is … most valuable … for those who have yet to build their K2.”
“… you guys have produced some very fine boards! … my compliments on some very nice work.” [RE: our rev. G headers circuit board]
“I’d recommend the rework eliminator. … It makes adding options much easier … you don’t have to rework your basic kit when you add a board. You can also remove an option … to isolate a problem.”
“Another option that I highly recommend. … when you do build / add an option, you don’t have to do any rework …”
“… Rework Eliminators have been money very well spent.”
“… it was well worth it and went smooth as silk.”
“I love the whole rework eliminator[™]eliminator[™] concept!” “I think it is brilliant!”
“… the Rework Eliminators again showed their value. … I had to remove the DSP board … and I removed the SSB and noise blanker … It took all of about 15 seconds to put the unheaders back in place of these boards …”
“… it made adding all of the internal options a breeze … I highly recommend them …”
“Thanks for the nice kit. … Good job guys!”
“… a big THANKS … for coming up with the K2 UNPCBs. … I am using the heck out of them trying to diagnose a bug in my K2. … I would have made a real mess pulling and replacing options a bizillion times.”
“FANTASTIC idea!! Thanks for your ingenuity and creativity … and sharing it with the K2 family.”
“An elegant solution … with professional execution from start to finish.”

“… thank you for making a nice, nifty product. … they’re a nice match for the K2.”
“… your attention to detail and customer satisfaction is simply amazing. Thank you …”
“I was especially impressed with the … circuit board (rev. G) … It is an excellent, well engineered product.”
“I recently had problems with the KSB2 … It was great … to do A/B comparisons and troubleshooting simply by unplugging the offending module and [plugging] in the header PCB.”
“I strongly recommend the use of these after market products if you plan to add options to your K2 in the future.”
“Thanks for your support on a great product.”
“… [they] make troubleshooting … easier.”
“Really like the concept and your 'execution' is 1st class.”
“Getting down and close with the PCB’s just impressed me more. The overall quality of the [new rev. G] boards and silk screening was matched by the thorough directions.”
“… I was very impressed with your [new rev. G] board layout. It is very well done.”
“The service you and Ken are providing is … amazing. A real class act.”
“… almost priceless …”
“… the Rework Eliminator is a great product. It came in handy when I needed to remove the KDSP2 to access TP3.”
“I wish I’d found you before I started the K2 …”
“… wish you had been around when I built my base K2. Would have made the upgrades sooo much easier.”
“… a nice commercial set for less than 20 bucks. … very handy. … I just grab the correct one and install it.”
“The kit looks great -- and your over-the-top passion for quality and a professional product does you guys great credit.”
“The quality of the [rev. G] boards is excellent.”
“The RE boards … eliminated unnecessary rework …”
“What a great feeling to just unplug the RE board, plug in the Elecraft Option and have it work … that really made it worthwhile.”
“I have Rework Eliminators in my K2 and I highly recommend them.”
“It’s a great idea. … very professional … they are bargain priced …”
“… use more superlatives to describe the frustration that will set in every time you have to disassemble the K2, and the risk for real board damage.”
“… very nice indeed.” [RE: our rev. G headers circuit board]
“I have just finished the 160M card for my K2 and as I read the instructions of what I would have to do to install the card with out the Rework Eliminators installed I say again THANK YOU. There is no comparison.”
“Thanks again for an excellent, well engineered product!” [RE: our rev. G headers circuit board]
“… and for your superb customer service!”
