Quick question / comment about the noise in my system. After listening to it more I have highlighted two distinct and separate noises.
The first is engine / alternator whine, is linked in with the RPM. I'm guessing an inline ground loop filter might help with this? Such as

I am also getting some noise from the computer. With the DAB_Master test app, after I open the COM port I can hear what sounds like Morse code, beeping on and off. If I close the port the radio continues to play, but the sound stops. Similar to this I also get some noise when I touch my touchscreen, this is more noticeable if I "drag and drop" something as I am touching the screen for longer than just a press. Eg: if I drag the test app from one side of the screen to the other. Would a better shielded cable as discussed earlier help with this?
Just trying to work out if I need one or the other, or both.
Thanks, Tom.
