13 cm DATV with just an Android phone and two cheap ESP32 boards, no PC 📡📺 ATV RX/TX is an open-source app: 📥 RX: an ESP32-S3 on USB OTG samples the 2.4 GHz band; leandvb on the phone demodulates DVB-S2 (QPSK/8PSK, 40–500 kS/s) and shows the picture, spectrum, constellation and MER 📤 TX: the ESP32-C3's own Wi-Fi radio is the transmitter. The phone encodes the camera or a test card to H.264 and DVB-S2 itself and streams the symbols to the C3 📌 Stand-alone beacon: record a loop with your callsign on the phone and store it in the C3; it then transmits by itself after every power-up 🔧 Firmware for both boards is flashed straight from the app Based on SP8ESA's ESP32-DATV and TA7W's ESP32-DATV-SA. Thanks! APK and guide: github.com/ok1cdj/ESP32-ATV For licensed radio amateurs only. @BATCOnline @hackaday @EspressifSystem #hamradio #DATV #ESP32 #DVBS2 #SDR
