Ok thank you for the tip 

Hello,and thanks for all your help  I already checked the radio, remove the usb charger and confirmed the noise comes from the motor when it accelerates the buzz increases and vice versa when decelerating the noise decreases I will have to check all the ground connections

Thank you Jaribu7252 and Bosi72 I will check those points and thanks for the link 

Hello everyone

Ask if someone can help me with my next problem

I have an MGL V6 radio installed in my ELA 07 gyrocopter with Rotax 914 engine and I use Flycom helmets

The problem I have is that when they speak to me I hear a buzz in the reception  I thought it was the gasoline pumps but when I turn off the engine and leave the electric pumps on, the buzz stops, the noise is coming in when they call me or when I listen to the ATIs

I already checked all the ground ok antenna ok Also I put another radio with its harness and the same thing happens The interference is being generated by the engine when it is on, has this happened to someone?

THANKS FOR YOUR HELP 

ANTONIO
