| | ===== LoRa APRS Background ===== |
| |
| For those that don't know, APRS over LoRA is exactly what it sounds like: [[https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System|Automatic Packet Reporting System (APRS)]] packets sent using using [[https://en.wikipedia.org/wiki/LoRa|LoRa]] radio modulation, instead of the more common FM modulation used in standard APRS. | For those that don't know, APRS over LoRA is exactly what it sounds like: [[https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System|Automatic Packet Reporting System (APRS)]] packets sent using using [[https://en.wikipedia.org/wiki/LoRa|LoRa]] radio modulation, instead of the more common FM modulation used in standard APRS. |
| A LoRa-only APRS map can be found at [[https://lora.ham-radio-op.net/]], though packets from LoRa based devices are still found on common APRS sites like [[https://aprs.fi/|aprs.fi]]. | A LoRa-only APRS map can be found at [[https://lora.ham-radio-op.net/]], though packets from LoRa based devices are still found on common APRS sites like [[https://aprs.fi/|aprs.fi]]. |

| The digi runs on a Lilygo T-Beam v1.2 with an SX1262, and uses the firmware from [[https://github.com/richonguzman/LoRa_APRS_iGate]]. Tracker firmware for similar boards can be found at [[https://github.com/richonguzman/LoRa_APRS_Tracker]]. | There is also a new map and database specific to LoRa APRS running CA2RXU firmware ([[https://github.com/richonguzman/LoRa_APRS_iGate|iGate]] or [[https://github.com/richonguzman/LoRa_APRS_Tracker|tracker]]) is at |
| | [[https://lora-aprs.live/]], and this has the added benefit of including signal quality data which is not usually forwarded over APRS-IS. See the [[https://lora-aprs.live/help.html|help]] page for information on setting up your own device to feed this, it does not interfere with APRS-IS feed and can be operated alongside it with no problem. |

| | ===== Technical ===== |
| | |
| | The digi runs on a Lilygo T-Beam v1.2 with an SX1262, and uses the firmware by CA2RXU at [[https://github.com/richonguzman/LoRa_APRS_iGate]]. Tracker firmware, also by CA2RXU, for similar boards can be found at [[https://github.com/richonguzman/LoRa_APRS_Tracker]]. |
| |
| There are plans to create some interaction with the packet node [[nodes:gb7bsk|GB7BSK]] which is located at the same site, so you can interact with one from the other (within some limits, no large transfers over LoRa which would swamp the frequency!) | |
