I have a 9303 with a spektrum 2.4 mod. When I turn on the tx it is making a buzzing sound. Is this normal, or is there somthing wrong with it? I have never noticed this before..

Ok thanks for the reply! I just noticed it today. I guess it is the first time I messed with it when it was quiet. Lol. Thanks again.

I'm pretty sure it's not the voltage regulator that makes that high pitch humming sound. Rather it's the 2.4GHz circuitry.

Ha ha. I though the same thing when I got my first 2.4GHz radio. I was thinking maybe I needed to send it back to get it fixed. Sounds like some tiny crickets inside.
