Report Radio / Amp placement in vehicle in Technical Discussion Posted October 15 On 5/27/2021 at 7:28 AM, mbrun said: All electronics will handle extreme heat for some period of time, but heat is the enemy of electronics. How long is a complete unknown for every product. A radio sitting idle or in receive only mode will not generate as much heat as radio will when transmitting. When the radio is put into a closed compartment it will raise the ambient temperature around it constantly causing the radio to get even hotter when operating. Again how long it will last is a completely unknown and a complete guess. You may find that radio will last as long as you care to own it under your conditions. Ask yourself if there is a way to force some air through the console with something like a muffin fan when you get to the point you are transmitting on the radio a lot. Michael WRHS965 KE8PLM Didn't want to start a new thread so did the search and found this one. My remote mount TK-8180 has been shutting down after steady use on the trail. My timeout is set to 30s but often don't give it a lot of rest between TX bursts when on the trail. What I get is power off, blank screen, but a constant click-click from the speaker. It has never done this from idle. After pulling power from the unit and an hour or so of down time, it fires up and operates normally. Dawned on me that the placement under the passenger seat of my Cherokee XJ might have been a poor choice, now realizing that's the path of the exhaust and that I have the heater going full blast at times while hunting, and with folks in the back seat. I looked through the service manual and it states operating temp to 140* F. What I was looking for is whether there's a High Temp Shutdown or fail-safe on these radios. Did not find that. Regardless of whether it gets that hot under there and rather than shotgunning replacement components, I thought a good first step would be to move the equipment. Prolonged radio life would be a big bonus as well.
