"If you can figure out how to keep the relatively thin "Z" panel from expanding and contracting as it is heated and cooled, you will have a solution to the problem."
If the Z bracket really is the source of the noise, and I'm not yet convinced it is, then there is no need to stop it expanding and contracting. All that is needed is to change the mechanical interface between the Z bracket and whatever is binding and releasing to cause the clicks. My plan was to put thin Mylar sheet between the Z bracket and the parts to which it is attached. I was going to start with the Z bracket to heat sink interface. I was not willing to do that until I had characterized the Z bracket temperature dynamics and understood the heat flow between the Z bracket and the heat sink. I have the data but no longer have the clicks. 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]
