That phase modulated data is a real pain. In the Scottish borders Droitwich
beats with Westerglen (between Glasgow and Edinburgh) which either doesn't
have phase mod data, or has different data on it. The net result sounds as
if the Daleks have taken over radio 4. Surely there are better ways of
signalling to electricity meters or whatever it's for?

Yes, but it is not so easy to use "right out of the box" because it has a
lot of phase jitter (intentional PSK) that has to be smoothed out.
