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

kQSO 1.9 is out 📻 Any Icom now works with the logger through the little M5Atom: band, mode and frequency from the radio, tune it by typing in the log. IC-705 over Bluetooth as before. github.com/ok1cdj/kQSO Build the keyer and CIV interface: keyer.ok1cdj.com/build.html #hamradio #SOTA #POTA #amsat #icom

M5-ESP32-keyer v2.1.0 is out 📻 New: Icom CI-V support. The keyer now reads the frequency and mode from the radio and shows them on the AtomS3 display, the web page, and over BLE to logging apps. • finds the baud rate and rig address on its own and remembers the rig • needs only one MOSFET (BSS138/2N7000) for the level shifter, wired from the Grove port • CI-V tunnel lets a logger tune the radio through the keyer • the display can now be rotated Tested with an IC-706MkII.
