APRS 438

Welcome to the home of **APRS 438**, the 438 MHz LoRa APRS amateur radio project that **extends range by saving bytes.**

Unlike some other ham radio LoRa APRS projects, this white paper and project aims at deploying LoRa the way it was intended; namely by being frugal about the number of bytes put on air. Doing so, reaps a number of benefits:

  • less airtime,
  • increased battery life,
  • higher chances of good packet reception,
  • hence, increased range,
  • lower probability of packet collisions,
  • therefore, more channel capacity.

The documentation of this project was moved to https://aprs438.readthedocs.io/
