Hi Stefan,

I suggest that you cover the LPF and FET with a piece of tin to stop any external signals entering the circuit after the LPF.

A thin piece of metal from coffee tin or similar food container can be bent in a U shape to cover the components and then soldered at a few points to the copper ground plane.

Just leave a small clearance holes at the ends for the wires to pass through.
