One advantage of this type of connection is the ability for SREJ, or selective reject, to be used. Normally, several packet may be sent out in order, and if one of them is not received correctly the entire batch is rejected with a REJ message. The whole set of packets then has to be retransmitted. SREJ allows only specific packets to be rejected, so only those individual packet need to be retransmitted. | One advantage of this type of connection is the ability for SREJ, or selective reject, to be used.

- | ===== LoRA-APRS ===== | ||
- | |||
- | APRS over LoRA is also run under GB7BSK-10. Initially this is a separate system, but there are plans to create some interaction with the packet node so you can interact with one from the other (within some limits, no large transfers over LoRa which would swamp the frequency!) | ||
- | |||
- | This runs on 439.9125 MHz, Bandwidth 125khz, Spreading Factor 12, Coding Rate 4/5 (ie. enter " | ||
- | |||
- | For those that don't know, APRS over LoRA is exactly what it sounds like: [[https:// | ||
- | |||
- | In fact APRS packets are in the AX.25 format, just like regular packet radio, but it uses the format in a different way and so is not directly compatible at the protocol level with traditional packet radio. It is possible to run a packet node and/or BBS over the LoRa modulation as well, and GB7BSK may experiment with this at some point as well. | ||
