MATEK VTX 6-36V Video Transmitter, 1.2 GHz, 1.3 GHz
Caution: It is NOT RECOMMENDED to use channel 1 (1080 MHz), because the use of this channel coincides with the operating frequency of the ADS-B transponders (1090 MHz) of the piloted aircraft. ADS-B transponders are used for airborne identification as well as in the TCAS airborne collision warning system.
Setting:
Button A sets the transmit power: 0 (blue LED) = 0.1 mW, 1 = 25 mW. 2=200 mW, 3=800 mW.
Press and hold button B for 2 seconds to enter the frequency setting. The frequency indicator will start flashing.
Press button B to select the frequency (in US 2CH version only 1258 and 1280 can be selected)
While the LED is flashing, the transmitter is not working.
The new frequency and the transmitter will be activated if no button is pressed for 3 seconds.
Control from flight controller
Connect "RX" to any free UART-TX of the flight controller, enable "VTX (Tramp) protocol" on the appropriate UART.
Copy and paste the following command into the CLI of BF4.1 or later.
