DIGIPEATER IZ6RND-12
Digi Terminal

The ESP32 module REPORTER sends all APRS telemetry parameters via DRA818V, both in standard and complete mode, as well as communicating the system's position. This terminal displays the beacons actually received via VHF radio from the IZ6RND-12 digipeater repeater station
