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

  1. Open the Meshtastic app or Web UI.
  2. Go to Radio Configuration → LoRa.
  3. Select the correct Region / Preset (United States).
  4. Save and reboot your device.

For detailed instructions, see the official docs: [1]
