Hello,

I recently got my technician license and bought the tyt th 7800 mobile radio for my car. I read that the radio has a tendency to heat up with use and I was wondering if anyone has had any experience with this. I plan on leaving the main body of the radio under my seat and mounting the head near the dash and just want to insure that this won't be a fire hazard.

Thanks,
Jacob

In the past when I have used radios where the heat sink got hot, I would put a small 12 volt cooling fan to blow air on the heat sink. That kept the radio cool. Took 3 cooling fans side by side to keep my 100 watt MCS2000 cool.

TH-7800 come with a small cooling fan installed. I've had one of mine installed under the front pax seat in my Toyota Camry for about six months now with nary a problem.

Well then he's GTG. The radios where I added the fan did not come with one. Motorola Maxtrac, Kenwood TK 840, & 880, Motorola MCS2000. They got hot fast, but they were not designed for long winded hams. Just for "where's my next stop, or going to lunch now".

Hot as in fire and "hot" as in I burned the radio up are different , you really can't hurt a radio by hooking up a higher speed fan to agressively cool a radio, it will just protect it from thermal failure , from a long rag chew or exceeding the duty cycle .
