Via the ARRL: Kennedy Space Center Testing Improved Wind Profiler, Seeks Assistance from Hams

NASA Kennedy Space Center (KSC) will be testing an improved waveform on the 48-MHz Tropospheric Doppler Radar Wind Profiler (TDRWP) from Monday, November 25 through Sunday, December 1. The purpose of the test is to improve the instrument’s resolution and still operate within the assigned bandwidth. The TDRWP is used to assess and evaluate upper-level […]

via HACKADAY: Shmoocon: Delightful Doppler Direction Finding With Software Defined Radio

When it comes to finding what direction a radio signal is coming from, the best and cheapest way to accomplish the task is usually a Yagi and getting dizzy. There are other methods, and at Shmoocon this last weekend, [Michael Ossmann] and [Schuyler St. Leger] demonstrated pseudo-doppler direction finding using cheap, off-the-shelf software defined radio […]
