The main goal of this project is to extend functionalities of ham radios with addition of a small PCB board that contains ESP32 microcontroller. As such following features would be enabled: time domain scrambling (based on the HEKTOR 128 project) custom digital modes (modulated and demodulated by the ESP chip) more advanced messaging could be served as webpage by the esp chip itself or have a mobile client as Meshtastic wireless UART connection to the radio turning any radio into IoT device via JSON API served from the ESP The physical inteface layer between the ESPRI and the host radio will be through the Kenwood connector. The audio input and output (for the means of time domain scrambling) would be through the Kenwood connector.
