Hello Ed, I would caution you against trying your K3 in those temps. Minus 60 degrees F. is the coldest on record for Minnesota, and you experience far colder that that. The cold may do multiple things to the K3 if it has multi-layer circuit boards. I didn't notice if it does. Our club left a repeater in an unheated enclosure one winter. I would estimate it wasn't much colder than minus 30 degrees F. at that location. (To clarify for others, this is 30 degrees F. below zero.) I have seen what the multi-layer circuit board looked like. More specifically, the thru-the-hole solder connections from one layer to another were cracked. Maybe it was the type of solder used??? I'm sure circuit designs have changed since the first solid state rigs I described in the cold. LCD screens hadn't been heard of yet. I'm surprised they don't freeze and get damaged in your temps. It is interesting to read of your outdoor experiences. 73, Dick, n0ce ______________________________________________________________ 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]
