I'm a tad surprised, because it was pretty-much in the centre of Britain where it was, and now it's way up North. I had noticed at Rugby (which has hundreds of aerial masts which you can see as you drive past on the motorway) that the VLF transmission towers, 12 of them in an oval about half a mile across, had been taken down some time ago, but I never did know which of the rest was MSF. I have to say that the move (at least 100 miles further away) doesn't seem to have affected any of my clocks, so presumably the signal strength is still very good. I do find that interference can stop them, though - too near a CRT television is a good one!
