Engineers from the University of Utah have discovered a filter for wireless communications that allows users of electronic devices to download data more than 1,000 times faster. Andrew Paulson, project lead and terahertz researcher, has been working on this research for more than two years. Paulson started by considering how to tap into terahertz radiation, which is a band of … [Read more...]
Ham Radios Assist Police in Catching Indoor Drug Growing Operations
Ham Radio operators can assist police in catching indoor marijuana growers who are causing radio frequency interference. Operators can help by taking a radio and portable antenna into their neighborhood and using the radio to find the location of the often illegal plant being grown. This RFI can produce many different sounds. “It can be pops, it can be a buzzing sound, … [Read more...]
