Meshcore is a distributed mesh-network, similar to Meshtastic, but incompatible with it. Some say it is better.
The space has joined the network with a so-called repeater. We are talking with people to install a repeater in the light masts in the old stadium of FC Wageningen, which would put it at a height of ~75m. With that we should be able to see a really big area.
Space repeater
Repeater name: NURDspace_repeater
Chip: LilyGo T-Beam 1.1
Antenna: 6dBi Dipole
NOT currently battery-backed!
other member's repeaters
aetios: aetios_rp001
Melan: Melpeater
Folkert has one but it's not currently connected to our network.
other member's nodes
Sparcie: SPARCie (running from her place)
