LoRa APRS at 1 W performs comparable to narrow FM APRS at 5 W.
Yet, LoRa gives more accuracy from fewer lost data points. (More about APRS, LoRa)

LoRa modules allow people to use smartphones to send short messages without using the cell network. The Meshtastic app allows people to send messages to all nodes on the network.

We use APRS tracking to help keep volunteers safe in major events. Members need to carry VECTOR radios to do so. What if we could give members small trackers and let you use your own radio?

A small, low-power tracker may make our civic events work easier. LoRa (Long Range) is a proprietary modulation that uses chirp spread spectrum to achieve long ranges with low power use and high immunity to interference. We intend to use the 433 MHz version to test APRS, telemetry, and short messaging.

We need two to four people to help field test mini-trackers in June and July. Anthony VE7XAK has offered to lead the project and set up all the gear.
