Finding Radiosonde

Based on an article i the Danish OZ magazine december 2023 written by OZ2OE I wanted to build the described radiosonde receiver.

This is the Lora 433MHz board I bought at Aliexpress:
LILYGO® Disaster-Radio LoRa V2.1_1.6.1 ESP32 433/868/915Mhz WIFI Wireless Bluetooth Module 0.96 Inch OLED SD Development Board

The firmware has to be changed, so see it here: MySondy GO v2

Here some pictures of the display after update of firmware:

The ttgo can communicate with a android phone, install the app “MySondy GO”

The blue line is the recorded track, the red is the distance to the sonde. Shown are the last measures received. The left one with GP antenna, the right with external antenna about 8 m high.
