Frequency Settings for Meshtastic
Meshtastic uses LoRa radios, which operate on different frequencies depending on regional regulations. Using the correct preset is important to ensure you stay legal and compatible with the local mesh.
Ottawa / Canada Preset
For Ottawa and the rest of North America, use the following setting:
US/LongFast – 906.875 MHz
This is the community-agreed frequency band for our local mesh. It ensures maximum compatibility between nodes in the region.
How to Change Your Frequency
- Open the Meshtastic app or Web UI.
- Go to Radio Configuration → LoRa.
- Select the correct Region / Preset (United States).
- Save and reboot your device.
