This is bad news for those of us in the East of England who like to enjoy high quality FM stereo. Here in Cambridge, under ‘lift’ conditions, stereo FM is no longer fit for purpose because of co-channel interference. Had the band been as crowded back in the 1960s as it is today, I guess that the current stereo FM system might have been rejected as too vulnerable.

These problems are despite a 4-element external aerial and decent tuner(s), one with selectable IF bandwidth. In particular, there’s a continental station that causes annoying ‘birdies’ on the Radio 2 frequency of 88.9 MHz, forcing me to switch to DAB to silence the background. I guess that the North Sea offers rather little attenuation under these conditions.
