#mysterious #radio #weirdworld --------------------------------------------- A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies.

The following are three stories about strange messages and signals that left people bamboozled.
