--- - - - --- Hi Dennis, The details regarding finish were omitted from his report for the sake of brevity. In fact, Adrian evaluated four Cooler KX(TM) configurations, one each painted and unpainted Lite and Plus model. The reason this information wasn't included, is that the coating had no discernable impact on performance. Addressing your questions about size ... Fred offers two models: his original (Lite) model is 1.25 inches deep and his newer Plus model (which was introduced back in April as "Tropical") was originally 1.5" deep. However, in July he increased its depth by 7% to 1.59 inches. And yes, Fred's Matte Black finish is electrostatically applied / heat cured power coat paint, although the entire bottom (heat transfer) surface is unpainted. Fred also offers two choices of unpainted finish: a premium Clear Chromate Conversion undercoat; and raw aluminum (straight from the mill). 73, Gary KI4GGX webmaster http://www.ve7fmn.ca/ P.S. I encouraged Fred to rebrand his Tropical model as Plus, after one reviewer (on the eHam website) seemed to imply that the heatsink could be operated in direct sunlight without concern. Intuition suggests that an unpainted finish would be preferable for operating under intense tropical sun, although even that should be avoided (IMHO). ______________________________________________________________ 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
