Up to 7 W Power for Serious FPV Use

The Kimpok ALV3307AC is the most powerful version in the ALV330xAC series. It offers three operating modes: Pit Mode, 2 W, and 7 W. That makes it easy to match the transmitter output to your flying environment, antenna setup, range expectations, and local radio regulations.

Lower power settings are ideal for bench setup, testing, and shorter flights, while the full 7 W mode gives you extra signal headroom for more challenging FPV conditions.

• Pit Mode – low-emission mode for safer setup before takeoff
• 2 W – balanced output for stable transmission with less load
• 7 W – maximum transmitter power for long-range and demanding FPV flights
• LED display – fast access to current band, channel, and power level
• Quick power switching – easy adjustment with a single onboard button

64 Channels in the 3.3 GHz Band

The Kimpok ALV3307AC analog transmitter supports 64 channels across 8 bands, giving you more flexibility when matching your video link to a compatible receiver and choosing a cleaner frequency in the field. In FPV systems, image quality depends not only on output power, but also on proper frequency and antenna selection.

The supported frequency range covers 3060 MHz to 3500 MHz. The bands are labeled A, b, C, d, E, F, G, and H, with 8 channels per band. A short button press changes the channel, while a longer press switches the band.

IRC Support and Simple One-Button Setup

The Kimpok ALV3307AC supports IRC, making it easier to integrate with a flight controller and manage settings in more advanced FPV builds. At the same time, the transmitter can also be configured directly using the single onboard button, which is especially handy when you need fast adjustments out in the field.

• Short press – switches between 8 channels
• Press for about 2 seconds – changes the band (A-b-C-d-E-F-G-H)
• Press for about 4 seconds – changes the power level
• Press for about 6 seconds – enables or disables Pit Mode
• LED display – shows the selected band, channel, and power setting

This streamlined control method keeps things simple and practical. You can quickly check settings on the LED display and tune the transmitter without connecting a computer.

Cooling, 7–26 V Input, and SMA Antenna Connector

The ALV3307AC operates on an input voltage of 7–26 V, with the manufacturer recommending a 6S battery. It also features a 5 V output that can be used within your FPV installation, depending on the requirements of the connected components. Current draw for this version is listed as 1.84 A at 12 V or 0.88 A at 25.2 V.

The transmitter uses an SMA antenna connector for a secure and dependable antenna connection. Because this is a high-power VTX, proper cooling is especially important. For best results, install the module where it has access to airflow. Its compact size and 30.5 x 30.5 mm mounting hole pattern make installation easier in many popular FPV frames and custom builds.

Always connect an antenna to the SMA port before powering on the transmitter. Do not operate the VTX without an antenna attached, as this may damage the module. For best performance, mount the transmitter on the upper section of the frame or in a location with good airflow. Avoid standing too close to the active antenna, and use only frequencies and power levels that comply with your local radio regulations.
