Pete the cat thrasher horne

Pete the cat thrasher horn was a radio transmitter built in the United States during the Second World War. The device was designed to be used by a human in the case of a nuclear attack, to announce a warning to people within a radius.

History

Pete the cat thrasher horn was invented in 1941 by the engineer William E. O'Neil. The horn was tested in April 1943, during the American pre-emptive invasion of Greenland. It was designed by a radio and electrical engineer at the MIT Radiation Lab named William O'Neil who had been in charge of the radio program at MIT since 1941. The U.S. Army had approached the MIT Radiation Lab, where O'Neil was chief of the radio department, about building an emergency warning radio device. The MIT Radiation Lab accepted the task and built the Pete the Cat Thrasher Horn to test it. The first test of the horn was done in May 1943 at the MIT Radiation Lab. The horn was built to warn of a possible nuclear attack using an antenna made from a tin-lined copper coil, with a diameter. The horn was designed to transmit a warning on a radius within, as well as to detect rcraft and warships in the area. The horn was designed to work for at least a decade, with the battery, relay, and microphone included.

The horn had a speaker on the front and could be operated by a human. It would give a warning of a nuclear attack within 30 seconds, using a antenna. The horn could transmit a message that was stored on tape in case of a nuclear attack. It was placed in an attic of the MIT Radiation Lab in Cambridge, Massachusetts, for testing. The horn could not be heard more than away from the transmitter. The horn worked on 10 watts of power. The horn was able to detect rcraft and warships up to a range of from its transmitter. If it detected a plane, it would announce the plane's position, and, if it was detected by the transmitter, it would be announced as well. The device was able to detect rcraft up to an altitude of and was only effective when it could detect a ship or rplane in the area. However, if no rcraft or ships were detected in a radius, the horn would not send a message.

The horn was installed at the MIT Radiation Lab on Memorial Drive in Cambridge, Massachusetts, to test the device. It was a large copper coil with a small speaker and microphone, with a microphone and speaker at the top of the coil. It was tested in the spring of 1943, and was activated for the first time during the American pre-emptive invasion of Greenland. O'Neil thought that the horn had a good chance of being used for the purpose of an attack, and he also thought that it had potential uses for monitoring weather. The MIT Radiation Lab installed two horns: one for testing the warning system and one for monitoring weather. The horn was only tested during a few days in April 1943, and was not sent to the MIT Radiation Lab for testing
