Ranger Mods

Have discovered a few golden oldie channels on my DAB radio which up to now was always on FM. But when vehicle was running the DAB stations would chop in and out. From Google deduced it could be because of running lights, globes or similar. After trying a few light configurations came up negative
In frustration started isolating a number of electrical feeds from main battery which run the spare battery, internal box lights, box alarm etc, no go
In the end looked at the cabin fuse box, pulled the double fuse lead which powers the forward camera and full time rear facing camera, success
Does any one else have a similar problem, and would it be likely i have a power leak?

Update, radio unaffected by rear camera, forward video etc. Have pulled plugs etc to isolate
When i place it into drive, DAB cuts out, back into park,radio plays again?
Any clues

Digital signal blackspots. I get them on my 2020 Camry and the ol Ranger

Drop outs I have had seem to be due to digital signal blackspots. Often happens around the same spots when driving. Have had the volume reduce when reversing and sensors going off then not return to the set volume. Never had it stop altogether when in drive.
