Thank you very much for the comparison of the available heat sinks for the KX3.
I bought the KB8UHN heat sink and I am quite happy with it. Using his heat sink I am able to run Digital modes at 10 watts on 20 and 40 meters with no problems and my radio temperature is lower than the comparison at 5 watts. I did use the included heat sink compound so perhaps that makes a difference. I did some testing on my own using assorted heat sinks from old audio and video cards and found that almost any heat sink will make a big difference. Thank you for supporting the Elecraft KX3 with your aftermarket accessories. Randy Moore AI4CO -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Gary W.

The clear winner of his testing is the Cooler KX PlusT, which is produced by VE7FMN of Simply Better Manufacturing! This means claims that the PAE-Kx31 is "best-performing" are not substantiated by fact! (Actually, such claims are hereby dispelled by fact!) Adrian's test report can be found at ... http://www.ve7fmn.ca/this-is-cool/pdfs/performance_page/head-to-head.pdf --- - - - --- In other news ... 1) The Cooler KXT installation guide has (finally) been published. 2) Tech-Note #3 (PEM nut thread repair) was completely rewritten. 3) I recently added some of the nicest customer-submitted photos to Fred's homepage. Thanks to Matt (N2IDW) and Ed (W6ELA). 4) Before too long I hope to implement "instant checkout" for most if not all Cooler KXT customers. What makes this task particularly challenging, is that unlike the USPS (which offers flat-rate international mail) the cost of shipping via Canada Post varies by country. 73, Gary KI4GGX webmaster http://www.ve7fmn.ca/ Posted on behalf of VE7FMN ______________________________________________________________ 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 ai...@outlook.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
