Research Proves Tin Foil Hats Do Not Prevent; Increase Ease of RF "Mind Control"
The longstanding mythology around the use of tin foil hats to block the government and extraterrestrials from reading or controlling a person’s thoughts using radio waves dates back to the late 1920s. The scientific logic is that the foil helmets act as a Faraday cage, an enclosure comprised of a conducting material that prevents external electrostatic charges and … [Read more...]
Testing Requirements for EMC-Unprotected Test and Measurement Circuits
IEC 61326-2-1:2012 specifies detailed test configurations, operational conditions and performance criteria for equipment with test and measurement circuits that are not EMC-protected for operational and/or functional reasons as specified by the manufacturer. This second edition constitutes a technical revision and cancels and replaces the first edition published in 2005. Learn … [Read more...]
World's Tallest Broadcast Tower Experiences Interference
The world’s tallest broadcast tower, the 634 meter Tokyo Skytree, has experienced unanticipated radio interference, despite being twice the height of the next tallest tower in Tokyo - Tokyo Tower. The Sky Tree was completed in May 2012. The transfer of radio wave transmission from Tokyo Tower to Tokyo Skytree was originally planned for January 2013 but has been delayed because … [Read more...]
