I have a 9303 2.4 radio thats about 3 years old and I just notice that it makes a humming noise is this ok ? everything works fine.

There is nothing in this world constant, but inconsistency.

This is the voltage regulator that knocks the TX voltage down to a level that the 2.4ghz board can safely handle. All is fine my DX7 buzzes slightly as well.

Good luck
