Kimpok Analog Transmitter ALV3303AC

Kimpok ALV3303AC Analog Transmitter – 3.3 GHz FPV VTX with up to 3 W Output Power

Kimpok ALV3303AC is a 3.3 GHz analog FPV video transmitter built for hobby pilots who need stronger transmission power, flexible channel selection, and simple on-device control. This 64-channel VTX offers up to 3 W output power, Pit Mode, and IRC support for easy integration with your flight controller.

With its compact 50 x 36 x 16 mm form factor, SMA antenna connector, 7–26 V input range, and clear LED display, the Kimpok ALV3303AC is a practical choice for custom FPV builds. It is designed for users who want stable analog video transmission, broad frequency options, and quick setup without digging through complicated menus.

• 3.3 GHz analog FPV VTX for hobby and custom FPV setups
• 64 channels across 8 bands
• Output power: Pit Mode / 1 W / 3 W
• IRC support for flight controller integration
• Single-button control for channel, band, and power changes
• LED display for quick status checking
• Wide input voltage: 7–26 V
• SMA antenna connector and JST-6Pin cable connector

Up to 3 W Power Output and Pit Mode for FPV Setup

The Kimpok ALV3303AC lets you choose between two transmit power levels plus Pit Mode, making it easy to match the VTX to your flying style and setup needs. Lower power is useful for bench testing and short-range use, while the maximum 3 W output is made for more demanding FPV conditions where a stronger signal matters.

• Pit Mode – ultra-low transmission mode for setup and working on your model
• 1 W – a balanced option for stable video transmission and reasonable power draw
• 3 W – maximum output for more challenging FPV applications
• One-button power switching – fast adjustments without external tools
• LED display – clearly shows the current channel, band, and power level

64 Channels in the 3.3 GHz Band

This analog FPV transmitter supports 64 channels divided into 8 bands with 8 channels each. The wide frequency selection makes it easier to match the transmitter to your receiver and find a cleaner working channel depending on the environment. In FPV systems, proper frequency and antenna selection can make a real difference in video stability.

The frequency range covers 3060 MHz to 3500 MHz. Bands are marked A, b, C, d, E, F, G, and H, and both band and channel can be changed using the button on the transmitter housing.

IRC Support and Simple One-Button Operation

The Kimpok ALV3303AC supports IRC, making it easier to connect the transmitter to a flight controller in more advanced FPV builds. For quick field adjustments, the manufacturer uses a straightforward single-button control system for channel, band, and power selection.

• Short press – switches between the 8 available channels
• Hold for about 2 seconds – activates band selection: A / b / C / d / E / F / G / H
• Hold for about 4 seconds – switches power level
• Hold for about 6 seconds – enables or disables Pit Mode
• LED display – shows the currently selected band, channel, and power setting

This setup is especially handy when tuning your FPV build outdoors. You do not need multiple switches or complicated button combinations—basic transmitter settings are available directly on the unit.

Wide Input Voltage, 5 V Output, and Compact Mounting Format

The Kimpok ALV3303AC works with an input voltage range of 7–26 V, and the manufacturer recommends using a 6S battery. The unit also features a 5 V output, which can be used in your FPV installation depending on the requirements of connected components.

The 50 x 36 x 16 mm housing and 30.5 x 30.5 mm mounting hole pattern make installation easier in many popular FPV frames. The SMA antenna connector provides a secure antenna connection, while the JST-6Pin connector helps keep signal and power wiring organized.

What’s Included and Usage Tips

The package includes 1 x Kimpok ALV3303AC analog transmitter. The antenna and any additional mounting parts should be selected to match your FPV setup, receiver, and intended operating range. Before installation, it is a good idea to verify compatibility for the power wires, video input, and IRC line.

Always connect an antenna to the SMA connector before powering on the transmitter. Do not run the VTX without an antenna, as this may damage the module. For best cooling performance, mount the transmitter in a position with good airflow—ideally on the upper layer of the frame. Use only frequencies and power levels that comply with your local radio regulations.
