Yes, the BBC time 'pips' always were and remain good value.  However, if you have a 'Digital Audio Broadcasting' (DAB) radio in the UK, you need to be aware that whilst the analogue broadcast pips always were and remain spot on, the DAB pips can arrive up to three seconds late because of the digitisation process.  This isn't seen as the problem it might have been, because accurate digital watches and radio clocks are so common these days that a what was once seen as an essential service is no longer thought necessary. 

Another 'classic' which is the playing of 'Sailing By' by Ronald Binge  https://www.youtube.com/watch?v=dFdas-kMF74  before the late night BBC Shipping Forecast.  This was introduced to help North Sea trawler crews and others who had to listen to long and medium wave forecasts against a background of static and spurious signals get their receiver properly tuned in before the commentator started reading the actual forecast.  If I remember correctly, the early morning forecast was preceded by a medley of sea tunes, but it's a long time since I was required to get up to listen to it, so I'm not sure if it's still there. Dave P
