Re: [Elecraft] KX3 and Heatsink
When I bought my used KX3 there was a Windcamp heat sink installed. I have not much experience with high duty modes on full power because I can use the KXPA100 when power is a critical factor. But I think this solution is sufficcient, too. But it mostly is offered along with two side handles and a plastic cover and this set is not cheap despite the fact that it comes from china. Some time ago I saw a DIY solution from an italian ham which is simple, affordable, and not too ugly: https://kx3companion.com/2014/07/10/simple-cheap-and-effective-diy-heatsink-for-kx3/ And I think it will work for a KX3 when it would work for 5 CPUs. 73 Hans, DF3DD __ 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] [SPAM] K3S - High SWR on 6 Meters
For some reason, my previous post did not show up. *** PROBLEM SOLVED *** I had an old LPA/PA combo that was replaced with an upgraded LPA/PA combo. The new PA required a configuration setting that inserted 6dB of attenuation in the amplifier chain to avoid instabilities. The old combo would not reach full power if the attenuation was inserted, but the new combo was unstable unless it was. Keith at Elecraft and also K7HP both suggested the "fix" and that was indeed the problem! 73, Jim - N4ST -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Bob McGraw Sent: Tuesday, June 14, 2022 20:56 To: elecraft@mailman.qth.net Subject: [SPAM] [Elecraft] K3S - High SWR on 6 Meters Is the ATU in BYPASS or AUTO mode?

Re: [Elecraft] What is a reasonable turnover time to hear from Elecraft support:
Depends on the issue. In my case it was just some replacement K3S modules. Here is my time line for a recent issue. 4/12 - K3S PA failure reported to Elecraft 4/14 - Email from Elecraft with testing procedures. 4/20 - RMA received and LPA/PA returned to Elecraft 6/13 - Refurbished new style LPA/PA received 6/14 - Configuration assistance from Elecraft - Back on the air. So for me it was about 1 month from reporting initial problem to received "new" parts and that included a 2-week vacation by the guy handling the RMA accounting. FWIW, I never called Elecraft although they did call me to discuss testing procedures/results. 73, Jim - N4ST -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of CUTTER DAVID via Elecraft Sent: Wednesday, June 15, 2022 00:03 To: Stephen Dubin ; Stephen Dubin via Elecraft Subject: [SPAM] Re: [Elecraft] What is a reasonable turnover time to hear from Elecraft support: __ 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
