Here is a look into my ATU here at the radio ranch, W7TFO.  Nah, just kidding!  I wish!

This was shot at a diplexed 100 kW AM BC site.  2X50 kW @ 100% mod, do the math.

I'd close the damn door in a hurry, too!

Wow...  They must have had an Idea that something was not quite right before they opened that up. Pretty impressive arcs there.

I wonder what song was playing to cause some fire!!! The tuner seemed to be singing along with the music.
Someone will have to cut back on some power......

I'll guess and think that it started arcing when he opened the door. May have upset critical tuning at those power levels.

Naw...  He just broke the seal and let bad air in..  Don't breath on it!

Hearing the audio in the tuner at a high power AM station seems to be something that occurs whether there is anything wrong or not. It just happens. But the flame shooting out of that coil sure isn't normal. My arcs and sparks that I've made with my tuner and my amplifier have nothing on that one.
