सामान्य प्रश्न

Q1: Does the video signal search run continuously in a loop from 500 MHz to 8000 MHz, or do I need to press the search button each time?
ए 1: NS Wideband FPV VRX supports continuous auto-scanning. During the search process:

• If a video signal is detected, the VRX display will show a clear video feed.
• To lock onto this frequency, दबाओ SET बटन. Without locking, the receiver will automatically move to the next frequency after 3 सेकंड.
• Pressing SET again unlocks the current frequency and resumes the automatic scanning process.
• When the scan reaches 8000 MHz without finding a video signal, it will automatically restart from 500 MHz, continuously looping through the frequency range.
• The search will keep cycling until a signal is locked manually using the SET बटन.

This ensures uninterrupted scanning across all bands while giving you control to lock onto any active FPV video channel.

क्यू: Can I connect an external device (जैसे, ESP32) to the receiver to read or modify the frequency?
ए: हाँ, it is technically possible. Some customers have purchased samples and implemented their own custom modifications. तथापि, please note that we do not provide technical support for such secondary development. Customers would need to handle this independently.

क्यू: Does the receiver support frequencies that are not included in the preloaded channel list?
ए: हाँ. For frequencies outside of the preloaded channel list, the receiver supports automatic scanning within the 500–7300 MHz range.

Q1: What type of video signals does 500MHz-8000MHz 8G Ultra-Wideband FPV Video Receiver support?
ए 1: It supports standard analog video formats NTSC and PAL and automatically detects the correct format.

Q2: Can it work with drones over long distances?
ए 2: हाँ, depending on antenna and environment, it can receive signals up to 50 किमी.

Q3: What power supply is required?
ए 3: A regulated 12–28V DC power source is required.

Q4: Is the device safe to operate without an antenna?
ए 4: नहीं, always ensure the antenna is securely connected before powering on to prevent damage.

प्रश्न5: Can I lock onto a specific channel?
ए5: हाँ, it allows both automatic scanning and manual channel locking for stable reception.

Q6: Can it be used in high-temperature environments?
ए6: It should be used in ventilated environments to prevent overheating.

क्यू 7: Can your VRX work with future transmitters outside the 6–7 GHz range?
ए7: हाँ. Our VRX frequency range is 500–8000 MHz, not limited to the 6–7 GHz band. This means future transmitters supporting a wider frequency range will still be compatible with our receivers, ensuring flexibility for long-term upgrades and diverse applications.

क्यू: The specification states that the receiver works from 500–8000 MHz, but the product description only shows part of this range. Can you provide the full frequency range and explain how to tune it?
ए: हाँ. The receiver fully supports 500–8000 MHz.

क्यू: Does this 500–8000 MHz FPV VRX come with a remote control? so I can manually enter a frequency to search channels.
ए: वर्तमान में, it does not include a remote control for manual frequency input. The receiver automatically scans channels within a preset range of commonly used frequencies. Please test the sample first. If you confirm that manual frequency input is required, we will develop this feature for you and can customize the device to support manual frequency entry for channel searching.

क्यू: Does the UWB VRX support automatic frequency hopping between different VTX bands (उदाहरण के लिए:. 1.2 गीगाहर्ट्ज और 3.3 गीगा)?
ए: Although our UWB (Ultra-Wideband) VRX supports a wide tuning range from 1.2 गीगाहर्ट्ज से 7.2 गीगा, it can only operate on one frequency at a time.

The VRX cannot simultaneously receive FPV video signals from VTXs operating on different frequency bands, जैसे कि 1.2 गीगाहर्ट्ज और 3.3 गीगा. When the VTX is working at 1.2 गीगा, the VRX must be tuned or scanned and paired at 1.2 गीगा. If the VTX is switched to 3.3 गीगा, the VRX must also be retuned or rescanned to 3.3 गीगा, and the previous 1.2 GHz link will be disconnected.

इसलिये, automatic recovery or frequency hopping across different bands is not supported. The VRX supports frequency scanning and tuning within the same band, but it does not support cross-band operation or simultaneous multi-band reception.

क्यू: What is the gain of the UWB antenna? Is it omni or directional?
ए: The default configuration uses a दिशात्मक एंटीना with a gain of 6 dBi. You may also use your own antenna. सर्वोत्तम प्रदर्शन के लिए, it is recommended to use a narrowband antenna optimized for your target frequency range—for example, antennas designed specifically for 6.1–7.2 GHz can provide lower VSWR and higher gain than a general-purpose UWB antenna.

क्यू: Do you offer multi-frequency fusion VTX/VRX that combines two signals into one stable image?
ए: वर्तमान में, our FPV VTX and VRX systems do not support cross-band operation. Even with a high-power amplifier (जैसे, 5 W+), it is not possible to achieve 50 किमी रेंज using analog 1.2 GHz सिस्टम्स.

For extended range and stable cross-band operation, we recommend using our digital video transmission solutions. These systems support frequency hopping across bands, हस्तक्षेप से बचाव, and can maintain clear image quality and reliable links over distances of 50–200 km.

क्यू: Can I remotely change the frequency of this FPV drone repeater?
ए: वर्तमान में, the frequency must be adjusted manually using the buttons on the receiver and the on-screen parameters. If remote frequency control is required, your software engineer can implement it by reading the frequency-setting commands and connecting a microcontroller. Through a 100-meter Ethernet connection, the frequency adjustment commands can be transmitted remotely, allowing the operator and the remote controller to stay in a safe location while modifying video signal settings.

क्यू: I want to receive good signal strength from a drone without knowing its exact direction. Can I use an omnidirectional antenna for this purpose?
ए: वर्तमान में, there is no single omnidirectional antenna that can cover an extremely wide frequency range from 500 MHz to 8 GHz. To achieve full coverage across the receiver’s frequency range (1.2–7 GHz), engineers recommend using four separate receiver units, each with its own omnidirectional antenna, tuned to different frequency bands.

Recommended Setup:

टिप्पणियाँ:

• Each antenna covers a specific frequency range with relatively low gain.
• Using multiple antennas ensures the receiver can maintain omnidirectional coverage without needing to know the drone’s direction.

क्यू: Why isn’t the 4.5–6 GHz frequency range listed in the specifications?
ए: The frequencies shown on the screen are preset commonly used bands to make channel scanning faster and more convenient for users. Even if a specific frequency (such as 4.5–6 GHz) is not listed, the receiver can still detect and match it by using the automatic scanning function, allowing it to find the video signal transmitted by the transmitter.

क्यू: How much time is needed for a full scan in 5 MHz increments from 500 मेगाहर्ट्ज से 8 गीगा?
ए: A full scan typically takes about 15–20 minutes. If no signal is found, the device will automatically restart scanning from the beginning. When a signal is detected, the user needs to press a button to lock onto the current frequency and video; अन्यथा, the device will resume scanning to the next frequency after 5 सेकंड.

क्यू: Why does scanning take 15–20 minutes, and can I change the channel grid?
ए: The scanning range is very wide (500–7200 MHz), so 15–20 minutes is normal. The frequency step size (channel grid) is optimized in the firmware to balance scan speed and detection performance, and cannot be changed by users. To speed up coverage, you can run two or three devices simultaneously instead of relying on a single device.
