- Keep the antenna as high as possible because the ground absorbs the signal.
- Try to be at point B instead of point A. Because according to the transmission principle of the antenna, it propagates in an umbrella shape. The signal at point A is often very weak.
- The Transmitter frequency range can change to 1.4G or 1.34G.
- The receiver frequency range only supports 170-860Mhz, if you need 1.4G or 1.34G, you need to install a frequency down converter block at the receiver.
- We don't have the frequency down converter block now, maybe you can contact the below supplier. (Performance is much better than China supplier now)

ڊرون UAV وائرليس وڊيو ٽرانسميٽر ۽ رسيور Vcan1870 لاءِ COFDM رلي ريپيٽر ماڊل
From some UAV customers have measured 50km when they are testing, and the height of the UAV is about 300 ميٽر.
- If the transmitter modifies the wireless parameters such as constellation, GI, CR, and BW, the receiver must be restarted to lock and display normally.
- Another possibility is that your transmitter modifies the constellation parameters through the AT command, but the parameters are not actually written into the baseband board. You need to restart the transmitter board to confirm.
- Our one-way cofdm video transmission is not designed to consider your current usage scenario (fast switching frequency).
- This may not work, the delay of TX switching frequency involves many aspects, such as the delay of the encoder board itself (currently the main program processes parameter changes in a cycle of about 1 ٻيون), and the processing delay of the baseband board, so add It takes about 2 second to switch. The processing delay of the encoder board can be squeezed to within 1 second by modifying the firmware, but the delay of the baseband board is not easy to squeeze, and the most important thing is that it is not easy to update the firmware (you must return to the factory to use our equipment to update the firmware).
- Summarize:
The encoder board may be able to reduce the processing delay of 1 second by updating the firmware, but the delay of the baseband board cannot be squeezed, so the final optimized delay is about 2 سيڪنڊ.
- Our Vcan1726 can support one HDMI and one auxiliary CVBS audio and video input at the same time, which can be connected to external microphones and power amplifiers.
- The current software can only support one sound source, which can be modified and selected through the parameter configuration board, HDMI sound, or CVBS sound, and cannot handle two channels of audio at the same time.
- ڇاڪاڻ ته COFDM هڪ طرفي ٽرانسميشن آهي, both video and audio can only be transmitted in one direction. From the transmitter to the receiver, the audio cannot have a two-way intercom, just like an ordinary radio, which can only broadcast in one direction.
The UART command is here.
