Re: [Elecraft] Field repairs to K3s
Personally, I would read through the kit assembly instruction for the K3S and see if the module tests were helpful. http://www.elecraft.com/manual/E740259%20K3s%20Assembly%20Manual.pdf When you need more than that, I’ve seen awesome support on this list and from Elecraft support. They will often suggest a specific component to test and replace. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On May 26, 2018, at 11:07 AM, wrote: > > Well stated.

Re: [Elecraft] Field repairs to K3s
Gerald, There are no details for how to troubleshoot to the component level. In most cases, the FRU (Field Replacable Unit) is a board. In some cases, Elecraft support is able to assist with your troubleshooting as long as it does not get too involved. Many times customers have replaced components such as PIN Diodes and several such items. So if you have test equipment and troubleshooting skills as well as equipment and skills for repairing SMD circuits, it can be done without sending the radio to Watsonville. Be aware that level of skill is not the norm for the Elecraft customer set. It was the norm for K2 builders several years ago, but conditions have changed and the average customer does not have the capability to repair his own radio - especially since the circuit density has increased many-fold and we encounter many hams with "shaky hands". If you want a radio that you can build and thus have some knowledge about "what makes it work", I might suggest building an Elecraft K2 which is still a top performing transceiver. 73, Don W3FPR On 5/26/2018 1:50 AM, Gerald Capodieci wrote: Where do I look to see how to troubleshoot a K3s at the shack and just order the new parts.

Re: [Elecraft] Field repairs to K3s
If you are looking for a radio which won't fail, I suggest one keep your money in the bank. All new radios, all brands, have a known failure rate, out if the box, at one year, and two years. That is the reason companies offer a warranty. They expect some number but of units to fail during the warranty period. Nothing unusual about this fact. As to personally repairing one of the modern radios, unless one has capability to handle remove and replace surface mount components, as well as rather extensive test equipment and advanced knowledge of electronics, one is relying on board or modular exchange. This does involve the factory an leaves one with a nonworking product for a period of time. For a period of years I repaired many ham radio products for others. In probably a majority of cases I had to not only find and repair the original fault, but.I had to correct the attempted repairs of others. Like many other products, we are moving more and more to a toss and replace commodity.

Re: [Elecraft] Field repairs to K3s
I've done a couple of repairs on my old K3: blown pin diodes on the transverter board, and the corroded 12 vdc connector pins on the KPA3 amp. Have also done several component-level mod kits supplied by Elecraft. I think Elecraft will supply all K3 parts that are still in production and, if I'm not mistaken, they stockpile end-of-life components for future repairs. But you can't expect parts to be available forever. FWIW, I recently managed to find a ceramic filter for my Argonaut V that is out of production. I ordered directly from TenTec. Amazingly they still had a few in stock. 73, Drew AF2Z On 05/26/18 11:12, Gerald Capodieci wrote: Thanks Paul: You have some wonderful luck.

Re: [Elecraft] Field repairs to K3s
Gerald .. If you’re looking for the 50 page "troubleshooting and diagnosis" guide for the K3, it isn’t something you’ll find. But as others have said, this list and Elecraft support are invaluable resources. The K3 is largely built to be module replaceable. But the modules themselves are also repairable, as long as you’re willing to deal with SMD components. One of the several benefits of building one (as opposed to ordering a factory built version) is that it eliminates the fear of taking off the covers. Another is that you get familiar with what’s in the box, where it is, and will have at least installed it once. You just use the construction manual backwards to get it out again. But even a factory built radio does NOT come with one of those stickers that causes your warranty to be terminated if you “break the seal”. I built my K3 back in 2007 or so. I’ve been into it over and over again installing new or updated versions of boards, or applying updates to individual boards. I’ve never actually had a board/component failure (knocking very hard on wood), and think that’s the likely case for most of us. And it’s never been back to Elecraft to cut a trace, install a jumper or a new part, etc. YMMV :-) Grant NQ5T K3 #2091, KX3 #8342 > On May 26, 2018, at 1:50 AM, Gerald Capodieci wrote: > > Where do I look to see how to troubleshoot a K3s at the shack and just > order the new parts. > > I'm looking to buy a radio that does not need to be sent back to the > manufacturer for basic repairs.
