I ran a 25,000 watt transmitter into a dummy load with no fan on it for over 20 minutes. (If you're not sure what I'm talking about, radio transmitters need to have their output go to an antenna, or what's called a dummy load, something that will basically absorb and dissipate the energy safely). The transmitter remote controls did some freaky stuff, switched the backup transmitter (which is normally turned off) into the main antenna and main transmitter into the dummy load, then turned them both on. Then the remote controls failed, so I had to hightail it up to the site to check the conditions and shut down the rogue transmitter... 5pm, in rush hour traffic. I normally can make the ride in 10 minutes in a panic mode, today, when time was crucial, it took way longer. My bike started overheating while I was stuck in traffic, but I knew I didn't have time to pull it over, so I pushed it right on the red line... When I got there, the dummy load internals were glowing bright red and some resistor clamps were actually molten and dripping. It has a fan, and used to have an interlock so the transmitter couldn't be started without the fan on, but another engineer I work with disabled that interlock a few months ago with no real explanation of why. I turned on the fan and killed the transmitter, but after about 2 minutes, the fan started clanking. When I turned it back on later, the fan sounded like the blades were hitting something, so I'm sure it's melted. Anyway, I'll probably take apart the dummy load tomorrow morning. Pics of the carnage to follow ( if this post actually gets any replies).
