What's powering the RC Rx? ESC's BEC, or the HK UBEC?
If the latter, where in the circuit is the UBEC? Before (close to the battery) or after the LC filter?
ET OSD directly links the receiver and the video system so any noise at the Rx (servo noise, or
ESC noise) bypasses your LC filter. With the connections between Rx and OSD, you
may have also created a ground loop.
