| | The VHF-LoRa gateway function means packets received on LoRa are digipeated on VHF from [[aprs:mb7ubk|MB7UBK]], and packets received on VHF are digipeated on LoRa. This cross-band digipeating is done with the "directonly" setting in APRX for the VHF side, and there are rate limits applied more stringently on the LoRa side (though normal traffic for the area is well within these limits). |

| | ===== 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. |

| 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!) | 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!) |
