A hardware project has repurposed the Gemtek W1700K Wi-Fi 7 router's MediaTek MT7996 radio chip as a wideband software-defined radio receiver, capturing raw 14-bit IQ data at up to 320 megasamples per second. Custom firmware, built without any MediaTek code, drives the radio from cold boot and streams captured data over 10 GbE to a Linux host, which renders a live spectrum and waterfall display in a browser.
Veteran Spanish radio hobbyist Mauricio Molano used software-defined radios and directional Yagi antennas to capture FM broadcast signals from the Carolinas, over 3,700 miles away, during a sporadic-E event on July 19. He also documented an African opening in May that brought in Togo for the first time, and observed a distinctive 'barber-polling' waveform effect during an Azores opening from his station in Cáceres, Spain.
A new project compiles the GNU Radio DSP engine and its Qt GUI sinks to WebAssembly, letting users build and run software-defined radio flowgraphs directly in a browser tab without installing Python or GNU Radio. It supports the same .grc flowgraph files as the desktop app, includes sample flowgraphs and IQ recordings, and can connect to RTL-SDR, PlutoSDR or HackRF hardware through WebUSB.
