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.
