Excellent post by chaos, as usual: agree with getting the ham radio license, etc.
I have my general ham license and a Kenwood DH-T72A handi-talkie. I've twice left it in my vehicle on a hot day and the $50 lithium-ion battery pack that comes with the radio wouldn't power on. The heat seemed to toast the battery pack the first time, so, $50 later, I was up and running again. . .
The second time around silly me left the radio again in the vehicle on a hot day; wouldn't turn on, but finally did a day or two later.
Anyone else with similar experience with handhelds not turning on after being left in a hot car?
I'm reluctant to spend more for a second or a pair of radios, even Baofengs, if they will not be usable if the need arises on a hot summer day.
Thoughts?
