Last few minutes of #BBC #Radio4 on 198 KHz #longwave - recorded via UTwente #SDR in #Netherlands
Carrier is still present for the moment, with looped recorded message about alternative ways of receiving Radio 4, presumably this gets switched off after a few hours (as the whole idea of turning it of was because BBC were getting tired of electricity and maintenance costs)
Ever wondered how we find messages to post?
The answer: our army of sky drama farmers, who operate 400ish feeds across 40 countries!
Do for your town what has been done for the likes of Liberal, KS, or Valparaiso, IN - become a sky drama farmer today!

QuadRF uses Raspberry Pi 5 for 4×4 MIMO SDR, RF visualization, and scalable phased-array support
Um den Teilnehmenden möglichst viele eigene Erfahrungen zu ermöglichen, habe ich für den Praxisteil meines „Hacking- und Pentest-Hardware-Workshops” fünf verschiedene Stationen mit Hardware entwickelt. An der fünften Station „SDR & Funk” dreht sich alles um Funkübertragungen, die nicht WLAN, Bluetooth oder RFID sind. Hier werden Fernbedienungen von Alarmanlagen geklont und Replay-Angriffe auf Funkübertragungen durchgeführt.

Visualize radio signals with Raspberry Pi 5-based QuadRF 4×4 MIMO software-defined radio tile (Crowdfunding)
QuadRF is a 4x4 MIMO software-defined radio (SDR) tile powered by a Raspberry Pi 5 SBC that functions as a real-time RF camera, allowing users to visualize radio signals in their environment using a phone or computer running an augmented reality app. QuadRF measures differences in signal arrival time using four coherent antennas and renders a live RF overlay directly on your phone or laptop at 30 FPS, letting you see RF signals from Wi-Fi devices, wireless cameras, smartphones, drones, beacons, and lab transmitters. QuadRF specifications: Compute & Signal Processing Raspberry Pi 5 SBC for onboard computation and control. Lattice ECP5 FPGA (LFE5U-45F-7BG256I) for distributed DSP and beamforming. Analog Devices MAX2850 (Upconvert) & MAX2851 (Downconvert) Mixers. 5.6 Gbit/sec MIPI data path between the RF FPGA and the Pi 5 Direct local processing on Pi 5 or network streaming for external processing. RF & Wireless 4x Rx / 4x Tx full-duplex
