I understand that MW radio is lower quality than FM but yesterday when trying to listen to the Euros I noticed a distinct pulsing interference. It's definitely ground speed related and not engine speed related.

I haven't noticed this before and was wondering if anyone had come across this?

The only thing I could think it might be that's electronic and ground or wheel speed related would be the abs sensors but the pulses (and I'm guessing here) seem to be at most a single pulse for each wheel rotation but probably even less, like one pulse every two or three wheel rotations.

I don't listen to MW often but have certainly never had this before. Last week I had my brake disks replaced and was wondering if it was related. I'm not a big believer in coincidence.
