I checked the interior of my K3 with the new KPA3A 100 watt PA module installed. There is an L-shaped hold-down bracket on the rear edge of the KPA3A board, which is secured to the rear fan panel with a single screw (not visible from the top opening of the case). It matches the dimensions of the bracket you found.
I believe its function is to keep the two connecting pin headers fully inserted, especially after shipping/travel. However, I can't find mention of it in the KPA3A installation manual, nor is there an errata sheet for that manual on the Elecraft web site. I can't recall if the installation manual that came with my KPA3A module also had a paper note regarding that bracket. If the bracket was free-floating inside the case, it may also be that the nut/lockwasher used to hold the rear panel screw in place may be jammed elsewhere in the chassis - check carefully! 73, Mike, K8CN ______________________________________________________________ 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
