"I'd appreciate a pointer to any discussions of Z bracket clicks. My search didn't find anything."
I looked again and this time found some discussion here - https://forums.qrz.com/index.php?threads/elecraft-kpa500-pinging-during-operating.591521/ and here - http://elecraft.365791.n2.nabble.com/KPA500-Heat-Expansion-Pop-td7075132.html. Reading between the lines I get the impression Elecraft tried to fix the problem, found they had not, so wrote in the manual that it is normal. I'd still like an answer to the question I asked April 21, 2018 - "To what extend does the thermal design require conduction between the PA heat sink and the case metalwork? Would the thermal management be compromised if very thin mylar strips were placed between the heat sink and the case side panel , case rear panel, or Z bracket?". Would someone at Elecraft please respond to this. Thanks and 73, Andy k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
