Late digital pips

SIR – Paul Grimsdell (Letters, January 6) explains why the sixth pip of the BBC time signal is sometimes missing from digital radio.

Surely the more important fault is that the BBC’S digital broadcasts of the time signal are three seconds later than FM broadcasts.

My clock, radio-controlled by the National Physical Laboratory transmitter in Cumbria, tells me that the FM broadcasts are correct.

Can’t modern digital broadcasts of the time signal be more accurate? Alan Williams

SIR – Some years ago, the last bar of a Mozart symphony over-ran the beginning of the 8am time signal on Radio 3.

The announcer drily remarked: “I trust the Mozart did not interrupt your enjoyment of the pips.” David T Price
