Why is my Fat Shark Transmitter reception so poor?
- E
  Eric Thomas DVMAug 5, 2025
  Poor reception with your Fat Shark Transmitter can occur for several reasons: * Using RP-SMA antennas instead of standard SMA connectors. * RC antennas being too close to video antennas; maintain maximum separation. * Shadowing of the VTX antenna; try a different VTX antenna with a longer coaxial section. * A loose VTX antenna connection; ensure the VTX antenna and any adapters are secured. Disconnecting during operation can degrade performance and damage the VTX. * VTX entering overheat protection mode; cycle to a different flight mode. * Overheating; disconnect power and allow cooling, then reconnect. * Poor airflow; improve airflow to the video transmitter RF board or add a cooling fan. * Loose MMCX connection on TX5M.1; ensure the MMCX connector is seated securely.

What to do if video recording is not working on Fat Shark Transmitter?
- A
  Ashley ReedAug 14, 2025
  If your Fat Shark Transmitter isn't recording video, it could be due to: * The SD card not being in FAT32 format. Use another device to format the card to FAT32. * Insufficient space on the SD card (less than 200MB available). Replace the card or clear space. * An unstable video signal. Focus on improving the reception first.
