| MB7UBA runs APRS over LoRA. | MB7UBA runs APRS over LoRA, located in Basingstoke, Hampshire (IO91kg). |

| 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. | ===== LoRa APRS Background ===== |
| |
| 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]]. | 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. |

| 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]]. | While packets are still logged via APRS-IS and viewable on common APRS sites like [[https://aprs.fi/|aprs.fi]], or LoRa only equivalents like [[https://lora.ham-radio-op.net/]], much more detailed information about LoRa APRS specifically can be found at [[https://lora-aprs.live/]] for devices running the very common CA2RXU firmware ([[https://github.com/richonguzman/LoRa_APRS_iGate|iGate]] or [[https://github.com/richonguzman/LoRa_APRS_Tracker|tracker]]). |
| |
| There are plans to create some interaction with the packet node 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!) | This has the added benefit of including signal quality information which is not captured through APRS-IS, and also preserving all activity rather then the de-duplicating of packets that occurs on APRS-IS, so you can see in detail exactly where you're packets went. |
