Pigeons are sensitive to electromagnetic fields, so they say. True or not? Time to put this to the test. I have a regular visitor, a turtle dove, who takes a daily nap on one of the radials of my 5/8 wave vertical for 10 meters. He/she must really like it there, almost every day, the bird is present.
I set my Yaesu FT-840 to 29.300 MHz, FM mode, and the initial power output to 5 Watts. No reaction. At 10 Watts, the bird raises its head and starts to look around a bit. At 15 Watts, my feathered fan becomes restless and starts to hop around. At 25 Watts, the turtle dove takes off.
I repeated the test a few times, just to be sure. On average, the turtle dove leaves my antenna when the power is around 25 Watts. Amazing, these animals.
