This project is intended to be coupled with my other LoRa board based project, 70cm Ham Radio Fox Hunt Beacon, which can be found at the link below:
https://lora-ham-fox-hunt-beacon-70cm.sourceforge.io
The receiver, also ESP32 LoRa-based, is designed for simplicity and accessibility, requiring minimal user setup. It features an OLED display providing real-time frequency readout and received signal strength indication (RSSI), presented numerically in dBm, as an S-meter value, and via a graphical bar. The system supports direction-finding applications, with provision for a compact 4-element Yagi antenna to enhance signal localisation.
CODE FOR THIS PROJECT HAS NOW BEEN RELEASED.
