4. Setup u Installazzjoni
4.1 Konnessjoni tal-antenna
Connect a 5.8G antenna to the MMCX socket on the VTX. Ensure the antenna is securely attached before powering on the VTX. Operating the VTX without an antenna can cause permanent damage.
4.2 Wiring tal-Enerġija u tas-Sinjal
Connect the VTX to your flight controller or power distribution board using the GH 1.25 6P connector. Refer to the pinout diagram below for correct connections:
- DC 7-36V: Connect to your main battery voltage (2-8S).
- GND: Konnessjoni mal-art.
- VIDEO: Video signal input from your camera.
- IRC: IRC Tramp control signal from your flight controller.
- 5VOUT: 5V output for powering a camera (maximum 600mA).

4.3 Immuntar
Secure the VTX using the 30x30mm (M3) mounting holes. Ensure adequate airflow around the unit for heat dissipation.
4.4 Optional Separation
The VTX features a separable design along a dotted line, allowing for a more compact installation if required. Carefully separate the board along the indicated line as shown in the figures below.

5.1 Mixgħul
After connecting the VTX and antenna, power on your drone. The indicator lights on the VTX will illuminate.
5.2 Aġġustament tal-Livell tal-Qawwa
Uża l- Buttuna tal-Qawwa (refer to Figure 6) to cycle through the five available power levels: PIT mode, 25mW, 200mW, 600mW, and 1600mW. The power indicator light will change or blink to indicate the currently selected power level.
5.3 Band and Channel Selection
Uża l- Buttuna tal-Kanal (refer to Figure 6) to cycle through bands and channels. The band and channel indicator lights will display the current selection.
- Stampa qasira: Changes channels within the current band.
- Agħfas fit-tul: Changes to the next available band.
5.4 IRC Tramp Kontroll
For advanced configuration, connect the IRC pin to your flight controller. You can then use Betaflight OSD or a similar interface to adjust VTX settings, including power, band, and channel, directly from your FPV goggles or ground station.
5.5 Frequency Tables
The VTX supports Universal (40CH), American FCC (37CH), and European EU (26CH) frequency tables. Ensure you select the appropriate frequency table for your region to comply with local regulations.
6. Maintenance and Warnings
To ensure optimal performance and longevity of your RAD VTX, observe the following:
- Konnessjoni tal-antenna: Always connect an antenna before powering on the VTX. Operating the VTX without an antenna can cause permanent damage.
- Tkessiħ: The VTX generates heat during operation, especially at higher power levels. Provide constant airflow and ensure a well-ventilated environment. Consider installing a cooling fan if operating in enclosed spaces or at maximum power for extended periods.
- Indafa: Keep the VTX free from dust, dirt, and moisture.
- Voltage: Aderixxi mal-input speċifikat voltage range of DC 7-36V. Exceeding this range can damage the unit.
7 Issolvi l-problemi
If you encounter issues with your RAD VTX, consider the following general troubleshooting steps:
- Ebda Sinjal tal-Vidjo: Check all wiring connections, especially power, ground, and video input. Ensure the antenna is securely connected. Verify that the VTX is powered on and the correct channel/band is selected on both the VTX and your FPV receiver.
- Kwalità Fqira tal-Vidjo: Check for interference sources. Ensure the antenna is not damaged. Verify power supply stability.
- Is-sħana żejda: Ensure adequate airflow. Reduce power output if operating in a confined space.
For persistent issues, consult online FPV communities or the manufacturer's support resources.
