Cheap chinese rubbish again. People on here have sneered at me about
worrying about these voltage converters, saying who uses radios these days,
well...
My suggestion is a ferrit ring on the two sides of the circuit, but if its
built into one of the units it depends where its getting into the system,
if its through the electrics, than a choke and capacitor might sort it, but
if its radiating from the power cable to the dab aerial then apart from the
ferrite bead idea, I'm at a loss, You don't get such problems with the less
efficient series regulators as they are analogue. Of course it could be some
interference from the camera electronics, but that is less likely.

My DAB has been breaking up recently and the radio automatically drops to
FM. This is a bit annoying though die to the slight time difference.

Grubbing about on a Facebook Group someone asked if I had anything plugged
into my Cigar Lighter Socket - I have - a Dashcam. I unplugged it and the
problem went away.

It seems the 12v to 5v ciruit causes interference. I found a couple of
YouTube videos that seem to confirm it.

Now I need a solution!
