Thanks to everyone who contributed their experience of operating with min fan speed set above 0.
I have some ideas for a test series and I'll share anything I learn from it. Here is a teaser for those interested in KPA500 thermal management. Did you know that, for a KPA500 that has not transmitted for a long time, the Z bracket is hotter than the heat sink and the heat sink is hotter than the finals. For that condition the heat flow is from the Z bracket, into the heat sink, and then it heats the finals. The heat flow reversed during TX as the finals heat up. 73, Andy, k3wyc ______________________________________________________________ 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
