I was reading today that some hams are having issues with their portable rigs overheating and shutting down in the warm weather we have been having out west while doing POTA, and SOTA, activations.
I've never had that issue. My Dad taught me how to make a suitable sun/heat shade for any radio I might have that I want to operate portable.
The answer is a simple cardboard box big enough to fit the radio, painted gloss white on the outside, and flat black on the inside.
The gloss white paint reflects the suns rays and the flat black helps you see your radio in the intense sunlight. This idea is a lot cheaper than some of the responses to the original article.
Below are some photo's of the sun shade I made last year with my KX3. It works very well. This took me less than 10 minutes to make, and the only expense was two cans of spray paint. I hope this idea helps somebody.
