Now that’s a power glitch!! This voltage surge was long enough to get captured on an old school mechanical pen recorder.
Colorized for no good reason:
(It’s physically impossible for the trace to reach the jackpot mark without blowing through the side of the meter movement. I was just being silly.)
Guess that explains why every time I’m looking at that transmitter the PA PLATE overload trip indicator is on showing that it had tripped and reset itself at some point. KABANG!!
