I think it is because the implementation of FM reception on some modern

Good reason not to buy new then. ;-) Since non of mine exhibit this.

Tuners sold as DAB tend to have this problem more than most. It
manifests as curious flanging effects as you move between the sound
fields of different radio receivers. It wouldn't surprise me if mobile
phones used a software solution for FM reception.

Different DAB tuners show it much more profoundly.

As do Freeview TVs both tuned to the same channel.
