Buzzing through earplugs?
I'm using the video out USB cable (bought from the Mobius website) to connect the Mobius camera to a 600mw tx Immersion RC (UNO5800 V2 5.8GHz RX, fatshark goggles Base model with ear phones).
The plan is to add this setup to a glider to use for thermal soaring and will install an L1D vario. I would like to hear the airflow noise and the vario, so I have wired up a Tiny Mic v2 using the power, ground and white audio cable from the TX. Power for the camera will come from a separate bec, for now the camera is running off it's internal battery to keep things simple.
I am receiving a good picture from the camera but hearing a buzzing noise through the earphone. The buzzing starts only when I turn on the camera, if the whole system is on and the camera off, no buzzing.
I have tried all three ground wires coming out of the camera mini usb cable but no joy. Any help to get rid of the buzzing would be appreciated
