Re: Feedback noise using dongle with power
It's dirty power from the charger, and a possible ground loop. Ground loops happen when two or more paths to ground exist and are at different potential. I run across this a lot in sound system installations, particularly in churches. Additionally, the 12V charger is probably picking up ignition "hash" and passing it on to the audio because of the ground loop. The inverter might solve the problem.
