I've had two Fords over the past 2 years, both with built in DAB radio.
I've noticed when driving around Sheffield there are various times when it goes silent and the message "station unavailable" appears on screen.
I can accept that this might happen near the tram tracks as I'm sure there is some interference from the overhead cables. However I have also noticed drop outs in areas away from the tram tracks.
For a while I put this down to blackspots etc. but recently became suspicious that this might have something to do with buses. At first it seemed coincidental, but more and more I have realised that whenever this happens there always seems to be a bus near by.
Tonight I was sat parked outside the chip shop on Abbey Lane for around 10 minutes without any interference when all of a sudden (without moving) the station went off. It happened exactly as the 76 drove past on the other side of the road.
So I was wondering if anyone else can corroborate my experience and if so, if anyone can explain why this might happen (and whether it should). I know it doesn't happen when going past every single bus, but I'm convinced it happens far to common for it to be a coincidence.
