I noticed that when the battery of my 100 gets low prior to shut down, the case gets warm. I’m guessing this is normal? The battery’s charge normally and LED on the charger goes green during day.
The SDS100 runs hotter normally. The plastic housing of the radio acts as a heat sync,
I always assumed they did utilize some sort of heat sync inside the plastic case. But the heat transfer between whatever they do use for a heat sync and the plastic outer case must have satisfied their concerns… otherwise, I would have expected a metal plate on the backside, for better transfer, and a note to hand carry the radio as much as possible, the palm of our hands used to draw heat out of the radio! That’s a bit extreme but I remember a small Kenwood portable ham transceiver I used for the 220MHz band, set to transmit the max power (needed to drive an external amp). That radio got so hot I couldn’t hold on to it! And I went thru 2 of them before I finally dedicated a true 220MHz radio with adequate power for my needs. That’s what I get for trying to do it on the cheap!Plastic is a very poor material to utilize as a heat sink. They should have integrated some low-finned aluminum heat sink plates somewhere in the case for that purpose.
