This is an update of ESP32S3 all-band radio receiver DIY project we posted before, which is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building an all-band (including AM, FM, SSB)radio receiver based on the SI4735 .
In aviation communication conventions, radio waves in HF range of 2-30MHz
and VHF range of 118-137MHz are commonly used as communication bands.The solution for radios to receive air band wave is as follows: add a pre-frequency conversion circuit including SI5351A,NE602, and 10.7MHz ceramic filter, and then send the the output wave to SI4735 for tuning.
The whole project is open-sourced on GitHub.
