About This Tool

This calculator implements the same frequency slot algorithm used by the Meshtastic firmware. It uses the djb2 hash function on the channel name to determine which frequency slot to use within the available spectrum for each region.

Important: For nodes to communicate, they must use the exact same channel name, modem preset, and be in the same frequency slot. This tool helps you determine the frequency slot for any given channel name.
