The LST 5.8GHz 48CH 2-8S 3W VTX Video Transmitter is a high-performance video transmission system designed for long-range FPV racing drones. Offering adjustable power levels, robust build quality, and advanced features like temperature control and smart audio compatibility, this VTX is ideal for drone pilots looking to enhance their video transmission capabilities. Below is a detailed breakdown of its features, specifications, and functionality.

Key Features:

Ø  48 Channels, 5.8GHz Frequency Range: The LST VTX operates within a 5.8GHz frequency range, providing 48 channels across multiple bands (A, B, E, F, R, L) with frequencies spanning from 5362MHz to 5945MHz. This wide range ensures that you can find the clearest possible signal, even in areas with heavy interference.

Ø  Adjustable Transmission Power: With power levels adjustable between 25mW, 1000mW, 2000mW, and 3000mW, this transmitter offers flexibility based on your FPV racing requirements. You can select a lower power setting for short-range flights or dial up the transmission strength to 3000mW for long-range applications.

Ø  Wide Input Voltage Range (2-8S Compatible): The LST VTX supports input voltage from DC 7V to 36V, making it compatible with 2-8S LiPo batteries, which provides broad applicability across different types of FPV drones.

Ø  Smart Audio via IRC Tramp: The transmitter supports IRC Tramp Smart Audio, allowing you to change channels, bands, and power levels remotely via your radio transmitter. This feature enhances the ease of configuration, making mid-flight adjustments possible without landing the drone.

Ø  Temperature Protection System: Equipped with a smart temperature protection feature, the transmitter automatically adjusts its power level if it exceeds 100°C. If the temperature remains high, it will step down to the lowest power level of 25mW until it cools down to a safe operating temperature of 95°C or lower. This safety feature prolongs the transmitter's lifespan and ensures reliable performance in various weather conditions.

Ø  Efficient Heat Dissipation: The transmitter uses an aluminum alloy heat sink and cooling fan to efficiently dissipate heat during operation, ensuring stable performance even during high-power transmissions and extended flights.

Ø  Compact and Lightweight Design: Measuring 37.7mm x 36.1mm x 11mm and weighing only 16g, the LST VTX is compact and lightweight, making it easy to integrate into any FPV racing drone without adding unnecessary bulk.

Ø  MMCX Antenna Connector: The transmitter features an MMCX antenna connector, known for its durability and secure connection, providing a strong, reliable signal during your flights.

Temperature Protection Notice:

The LST VTX is equipped with an intelligent temperature protection feature that actively monitors the transmitter's heat levels. If the temperature exceeds 100°C, the RF power output will be automatically lowered to the next available level. This continues until the transmitter reaches its lowest power output of 25mW to ensure it cools down effectively. Once the temperature falls below 95°C, the transmitter will return to the previously selected power level, protecting the unit from potential damage due to overheating.
