What kind of portable radio should I use in a walk-in freezer?
I work in a walk-in freezer and cooler and was wondering if there are any battery powered radios that would withstand really cold temperatures. I dont want to use headphones though.
this presents a two-fold problem.
First, the freezer box will prevent radio signal from getting in. This is called the "faraday effect" because the grounded metal box prevents radio wave from entering.
Second, the cold. Alkaline batteries lose electron production because of the chemical composition of the cell. You would need older zinc-carbon batteries.
Other than limited battery power and no radio waves, the cold does not effect the electronics. It may freeze the LCD display.

Best bet is to put the radio somewhere else and use a remote speaker in the freezer. Use the headphone jack of the radio to do this or use a stereo receiver and run the speaker wires into the freezer.
