The remote control device crystal frequency stabilization using pulse amplitude modulation transmitter, A simpler circuit, high frequency stability, launched 28MHZ are continuous carrier amplitude.

LED linear can be of warm or cold white color, multi-colored and RGB (with remote control), they also differ in LED disposing frequency on the linear and intensity.

Range of remote control device can radiate entire flight-run, and transmitting frequency throws no impact on airport and airliner communication.
