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.

"IO91pm is the Maidenhead-Locator for Maidenhead" ========================================= Background --------------- * For another little project, I wanted a QTH-Locator calculator for the UNIX (GNU/Linux, bash) command-line. * There are many, some very good, online QTH resources, but I wanted...

In this project a made a filed strenght meter to check my antenna. The fielduino have a sensitivity control (using a non inverting op-amp)

If you don't own a frequency-meter and if you are an amator-radio, this program is for you ! It allow to convert frequencies between 25.610 and 28.310 MHz.
