[Elecraft] K-Line Climate Control

[Dale Chayes]

While we are on the topic of being nice to our electronics, a dimension that many folks don’t think about down here in the “south” (of the northern hemisphere, specially when it’s > 90F outside) is powering-on “cold soaked” electronics:

if the physical hardware is cold enough (-20C / 0F) will often suffice, -40 is highly reliable) and you push power through “high power” electronics (e.g. power transistors) the very rapid thermal transition can cause fatal errors (as in letting the magic smoke out.)

Use the best quality equipment you can afford, treat it well, and it will serve for decades if not lifetimes.
