Working up a radio tower that is on top of a hill where 2 quarries are slowly cutting their way into.
Everything was fine until I hear a large bang and rumbling noises. Then the entire tower starts vibrating with the shockwave of explosion.
I was about 20M up the tower that day.
Also we now know why our millimetre wave radios will sometimes have jitters in the signal strength.
By using unrelated data to prove a point.
