Nodes

Medical District memphisme.sh v2 (👀)​

View !67812a87 on meshmap.net.

This node provides good coverage in the medical district, downtown, and in the neighborhoods nearby. The closer you get to the I-240 loop, the more marginal performance becomes, though rooftop nodes can consistently get connections.

This node is configured for LongFast preset and the default channel 0 with key AQ==.

Hardware​

This node is a MeshAdv Pi Hat running on top of a Raspberry Pi 5B. The node has a Callboost 915 MHz Band Pass Filter to help reduce adjacent interference, which this site has plenty of between cell, public safety, and hospital paging systems.

The node is inside a 2 post rack adjacent to amateur radio equipment from HamWAN Memphis Metro and Tri-State Repeater Association. From the cabinet to the tower, the site is fed with 30 ft LMR-300. The antenna is a MikroTik 915 MHz 5.2 dBi antenna.

Connectivity​

This node is configured to uplink to the official Meshtastic MQTT server on the us/memphisme.sh topic.

AI-enabled bot​

This node also is setup running the meshing-around bot, which provides basic ping/pong, web search, weather alert, weather forecast, and ask AI capabilities powered by a local Ollama and the Llama 3.2 3B model. Try it out by DMing the node "cmd"!
