I've been chasing down some noise problems in my bitx40 kit. For a start, my switching power supply is generating a _ton_ of noise. Using a 12V battery fixes that one. Now, when I plug in the Raduino, I immediately get noise very similar to the one presented in this video:?
I'd like to build a simple power supply filter as shown in the video, but I'm not sure where to start. He shows a RC filter in a Pi configuration. Would this go inline between the bitx and the Raduino on the 5 pin cable (P3)??
I'm hoping a filter like this will reduce the noise introduced by the LCD and other components on the Raduino.
Thanks!
