[Elecraft] What minimum temperature should the K station be kept at during a hard freeze

[Dave]

As mentioned by Bill, condensation and corrosion are perhaps more of an
issue than cold storage. Be careful if bringing cold equipment into a warm
room, condensation can quickly form...

Most amateur equipment doesn't mention storage temperature, only operating
temp. By way of an example a Rohde and Schwarz FPC spectrum analyser has a
temp spec of +10C to +40C (operating) and -20C to +70C (storage).
