While the video transmitter was turned on, the harmonics caused the RC control signals to be attenuated. The list below shows the interference through all the 15 channels.

			The test was done using a FrSky 2.4GHz rubber duck antenna on the transmitter and dipole wire antenna on the receiver, 12 meters apart. The video transmitter had a custom dipole antenna tuned for 1180 MHz.
