Good techs don’t come cheap, either, which increases overhead and inflates prices. Patience works to everyone’s benefit.

Re: [Elecraft] Possible K3s TX failure - distorted audio
Seems about right. My K3 arrived in Watsonville on Oct 1, and was shipped back exactly 30 days later. That said, it was the first time my nearly 10-year-old K3 had been back to the factory and the first actual problem of any kind I’d had with it. At the same time, they installed the front panel board gold pins (which may have been the actual cause of the problem I was having), put a mod in the KPA3, added a bracket, aligned it, and checked it. I’d been sitting on a set of those gold pins for quite a while in my “when I get a Round To-It” box of parts, and it’s probably too bad I hadn’t taken the time to put them in before some oxidation caused a problem. At least it’s done now, and I know my radio still meets or exceeds specs. 30 days was a small price to pay … even though it was a lonely time :-) Grant NQ5T K3 #2091 KX3 #8342 >> >> >> >> The current stated turnaround time for Elecraft repairs is 3 to 4 weeks. >> 73, >> Don W3FPR __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] Possible K3s TX failure - distorted audio
The biggest repair queue delay we get this time of year is when we receive an unexpected block of lightning damaged radios. That usually adds a couple of weeks to the repair queue. (We can easily determine where the lightning activity is around the country from the return addresses..) Don't forget to disconnect ALL cables from your radios, amps etc when lightning is near. We frequently see damage when the cables between the radio and computer are left connected. Nearby lightning strikes have a way of finding ground via almost any odd path. 73, Eric /elecraft.com/ On 11/14/2018 4:38 PM, Don Wilhelm wrote: The current stated turnaround time for Elecraft repairs is 3 to 4 weeks.

Re: [Elecraft] Possible K3s TX failure - distorted audio
Pete et al: I purchased my K3S 100-F in August of 2015. I experienced a failure in the form of distorted SSB audio in April 2018. Working with the techs at Elecraft they suggested and supplied a new KPA3A. That unit was received and installed and failed within a week. They then suggested the radio be returned for repair. It was shipped to Elecraft on May 8, 2018 and received at Elecraft on May 10, 2018. I shipped by USPS Priority Mail. It was repaired, updated and completely aligned and shipped to me on May 31, 2018. At the time I obtained my RA, the repair time was given as 15 to 20 working days. The radio was received by me on June 7, 2018 as it was shipped via UPS Ground. That overall project covers a span of 30 days or so. All seemed reasonable to me considering repair time and shipping time both ways. 73 Bob, K4TAX On 11/14/2018 4:13 PM, Peter Dougherty (W2IRT) wrote: Well here we are two weeks later.

Re: [Elecraft] Possible K3s TX failure - distorted audio
The current stated turnaround time for Elecraft repairs is 3 to 4 weeks. Given the staff techs with experience, that is the best that they can do. Oh, yes, "hire more techs" can be said, but that takes time away from those techs now working on repairs for training of new people, so initially the backlog increases until the new techs come on board.

Re: [Elecraft] Possible K3s TX failure - distorted audio
I did and sent in to factory to fix.

Early into CQWW this weekend I was getting reports of extremely distorted audio from my K3s. Being mostly a CW (and 6m FT8) operator I wasn't sure what was going on. I figured it was RF, but it was happening at all power levels, from QRP to 100W, and QRO with my KPA-1500. Same (bad) audio, just stronger/weaker signals. All bands were equally bad. I ended up going from the radio directly to the tower, physically bypassing the amp and tuner, and only running low power, with the same result. It sounded more like distorted audio than RF ingress. Some troubleshooting by Dave, WO2X, who is a Flex owner: He remoted in to his Flex a few miles away and noticed my garbled signal was absolutely dirty and wide, despite low mic gain and little or no compression. The audio sounded clean through the monitor, so it wasn't the audio chain. He's speculating I may have a blown FET in the PA stage. We put in a Flex 6500 temporarily and it seems to be running fine. Wondering if anybody here has had experience with this, and if so, what are my next steps? Thanks in advance. - 73 and Good DX Peter, W2IRT K3s S/N 10023 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to k9...@live.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
