What can I say?
35 years of diagnosing electronic problems leads me to the conclusion it's the new lights that are causing the problem.  Got - 2017 SDV8 Autobiography in Loire Blue

Interesting reading -

"I did some research on this and came across a lot of boat people complaining that after they had fitted LED lights in their boats they had problems with their comms radios. It would seem that it is the cheaper Chinese made LEDs that cause the biggest issue. It is because of the use of cheap switching power supplies that don't suppress EMI properly." Got - 2017 SDV8 Autobiography in Loire Blue

Certainly is ... my DAB ant is at the rear, and only close to my boot LED's. Will try leaving the engine on and opening the boot, there's 2 x 24 SMD chinese lamps in the tailgate and another 24 SMD lamp in the boot itself, as well as the 6 in the roof, so no doubt that should cause an issue.... Land Rover Addict

I got these and fitted the other day. Shows how well made they are that when I open the door, the DAB signal all but disappears!

Yep, can report the lights up the DAB signal when they are on Still, I don't often drive around listening to the DAB radio with the door open!  SDV8 AB MY 2019
