are a crucial configuration file in Betaflight (since version 4.1) that tell your flight controller exactly how to communicate with your Video Transmitter (VTX). They map specific frequency channels and power levels (mW) to commands sent via protocols like SmartAudio or IRC Tramp . Key Components of VTX Tables

Newer VTXs use SmartAudio 2.1+ (power in dB), while older ones use 2.0 (power in 0-3 values). vtx-tables

Defines available power output, mapping mW (e.g., 25, 200, 800) to dB values. Why You Need Them are a crucial configuration file in Betaflight (since

Are you trying to configure this in ?

In Betaflight Configurator, check the Presets tab for your specific VTX model (e.g., Rush Tank, TBS Unify). Defines available power output, mapping mW (e

Without a correct VTX table, you cannot change your video channel or power output via your radio (OSD/stick commands). If the VTX table is wrong, it may revert to default settings (often 25mW) every time you plug in your battery. How to Configure VTX Tables (Betaflight)

Maps channels (e.g., A1, R7) to specific frequencies (e.g., 5865 MHz).
