Not sure that would work, unless Elecraft had a different set of stencils for the through-hole user-installed parts. Othewise the solder paste would clog the holes. No - wait, these have to either be wave soldered or hand soldered (toroids), after the reflow. So they have stencils that mask the through holes.. But they can't do wave soldering in combination with reflow (that I've heard of yet). And hand soldering evidently is what is being done now for assembly of through-hole parts.
No wonder it's not optimum. As hams, we get the best out of technical user perception, because we actually look to admire the workmanship of radios we buy. Others look at the industrial design for guidance. We look inside. Hey - it's an idea after all. One may always ask. The real trouble(tm) with this approach is that the test eqmt at Elecraft no doubt assumes the RF board is completed. New TE costs $ to produce, and they haven't finished yet with what TE they need for MP. 73, matt, WA6EGJ On Sun, 04 Nov 2007 15:34:53 -0800, you wrote: >Craig NZ0R wrote: > >"You could avoid the problem by convincing Elecraft to ship a "torroids >(sic) only" version of the kit.
