I'm getting ready to build an HF / CW kit and just finished setting up a workbench in my garage. While I was wrapping up, I started wondering if the cold temperatures this winter might be harmful to any of the radio equipment. I live in Portland, OR, so I don't expect the temperatures to get too extreme, but it does seem possible for my garage to hit freezing temperatures. Are low / freezing temperatures known to be harmful to ham radio equipment?
To give a sense of what equipment I have on hand.. my shack is currently pretty simple - I have a pair of inexpensive VHF/UHF handheld HTs (BTECH UV-5X3), and will have the DIY HF radio on hand soon. In the coming year, I may add other equipment (e.g. power supply, tuner, an actual base station, etc).
It seems like electronics in general would be okay with the cold (it hasn't really occurred to me in the past to be worried about other electronics in the cold). At this point, though, I want to be really careful before leaving expensive equipment or hard-to-build projects in conditions that may eventually prove harmful.
Really appreciate any thoughts / advice!
