I have a Pi 4 which I have powered via a Mausberry 4AMP circuit.
I've noticed that when powered up there is interference in my FM radio and I've recently installed a DAB adapter to my headunit.
When powered on the DAB signal drops and radio disappears.
I've traced the issue back to the Mausberry circuit by powering the Pi with a powerbank which doesn't cause the issue.
Also when the Mausberry isn't sending power through its ports, by detecting via GPIO pins that is should shutdown, the interference is also not there.
I've seen similar issues with DAB and dashcam power and the suggested solution was to install ferrite cores on the cables, I did this for everything and this didn't fix the issue.
Has anyone else come across this issue or got any ideas?
