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
Raspberry Pi running piMc-repeater software. It has a signal booster.
Antenna: 6dBi Dipole
cavity filter
To improve the reception of the nurdspace repater, we're going to order a cavity filter: https://shop.sysmocom.de/868-863..870-MHz-cavity-filter-ISM-LoRa-SigFox-Helium/cf866.5-kt30 This reduces the noise significantly and thus improves reception. Kinda expensive device but the following people chipped in!
other member's repeaters
aetios: aetios_rp001
Melan: Melpeater
Folkert: vanheusden.com
other member's nodes
Sparcie: SPARCie (running from her place)
settings
- UK/EU narrow
- 869.618 MHz
- 62.50 kHz bandwidth
- Spreading factor (sf): 8
- Coding rate (cr): 8
- sync word: 0x12
- explicit header: true
- CRC: true
- preamble length: 16
See https://unsigned.io/understanding-lora-parameters/ for an explanation of these (and more) LoRa variables
meshcore channels
- #nurds => bridged to #nurdsmc
