"I guess that the 10uF electric capacitor connected to LM7805 output is a possible cause."
All the front panel LED seem to be on that same 5V rail and they stay normal brightness in the fault condition. I suspect something, other than low voltage is killing the MCU. It's still working over 30 minutes after the fridge cold soak. 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
