Here in Russia we have fun contest called "Frost the Red Nose" where
participants are awarded extra points for low temperatures. A lot of
participants operate in below freezing temperatures every year. Stories from
some of the participants (pdf file) can be downloaded here

Text is in Russian but there are many pictures that said to be "worth a
thousand words".

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.
