Even at 100C it is substantially derated. I was looking at devices designed for automotive use and quite surprised to see normal operating ranges up to 150C. The specs and real life performance are not always in sync............. > Hence the fact that Flex specs the operating range well below the device maximum specification. They built in substantial margin. But they are very forthcoming with the information. Just ask 'em. But I understand how you could be concerned. There is very little thermal mass in the 3000's PA heat-sink so temps rise very quickly once you key the transmitter. But the fan responds equally quickly and temps level off just as quickly. > As for the small pop-up window, I can't see any reason why that could not > be retained, even if the change a few of us would like to see is > implemented. > Well, you can just press control-shift-I at the beginning and the Info window with voltage and heat-sink temp is there. You can just leave it on the screen. Have you put in a feature request to make it persistent? That way its state would be stored in the configuration so if it was open when you turned off PowerSDR, it would automatically open when you started PowerSDR again. > It's good to see though that the radios can stand a "roasting". > For brute strength I really like the 3000. When I travel it goes in my backpack with the tuner and my laptop. It gets bounced and banged all over.
