News Summary

• The ESP32 series of microcontrollers have had hidden software-defined radio (SDR) facility revealed.
• This receiver uses a Seeed Studio Xiao ESP32-C5 board with a simple resistor-ladder DAC to produce the video.
• It has a simple button channel interface, and a serial link for more in-depth options.
• There’s no digital cliff-edge to lose your picture if you fly into somewhere with bad propagation of radio waves, and perhaps more importantly, it has an extremely low latency.
