W1700K SDR turns a Wi-Fi 7 router into a 320 MSps software-defined radio receiver

Just a few days ago, we wrote about the ESP-SDR project, which turned an ESP32 into an SDR receiver (and now SDR transmitter), but the data was streamed over UART, which couldn’t keep up with the sample rate. Now, developer h0m3us3r has released w1700k-sdr, also an open-source project that turns a Gemtek W1700K Wi-Fi 7 router into a wideband SDR receiver. The project uses the router’s built-in MediaTek MT7996 radio to capture raw 14-bit I/Q samples at up to 320…
