Horus 73 Takes Amateur Radio into the Stratosphere

The Amateur Radio Experimenters Group (AREG) in Adelaide is preparing for another ambitious Project Horus high-altitude balloon launch on Sunday 30 August, with Horus 73 scheduled to lift off from Mt Barker at around 10:00 am ACST. The balloon is expected to climb beyond 30 kilometres, potentially providing radio coverage across hundreds of kilometres of South Australia and western Victoria. The headline payload is an experimental 2 metre to 70 centimetre cross-band FM repeater, operating on 145.075 MHz uplink with 91.5 Hz CTCSS and 438.975 MHz downlink. Want to know more ?

Radio Telescopes Turn Radar Receivers to Track Satellites and Space Debris

Radio telescopes normally spend their time listening for incredibly faint signals from stars, galaxies and other objects across the universe. Now researchers have demonstrated that the same highly sensitive receiving systems can be put to another use: detecting and tracking satellites and space debris in real time. Want to know more ?
