The 434 MHz LoRa APRS project that extends range by saving bytes.

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/

Is the SX1268 chip supported?

Hi,

The docs mention support for the "TTGO T-Beam 433 MHz v0.7 or v1.1". There is a (new?) version of the TTGO T-Beam V1.1 with a SX1268 chip instead of the (older?) SX1278. This one has a bit more power and lower current draw. Is this chip supported as well?
