"Careful inspection of the air-spaced variable revealed a small bug between the plates. It was carefully extracted and viewed under the microscope. It was well charred!"
For the detail oriented - bug was identified as attagenus pellio (carpet beetle). They are common here in Arizona. They have a very high crush resistance but it seems poor tolerance of high RF voltage. https://en.wikipedia.org/wiki/Attagenus_pellio 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
