Welcome to the documentation of the APRS 438 Tracker, part of the 438 MHz amateur radio LoRa automatic packet reporting system that extends range by saving bytes.

Unlike the vast majority of other LoRa projects, the firmware of this project employs licensed frequency spectrum exclusive to the use of amateur radio. You need a valid amateur radio license to be able to use APRS 438 firmware. Contact your national government or local amateur radio club to find out how to obtain an amateur radio license.
