All radio controlled alarm clocks in the UK, pick up their time from NPL , which is a radio signal broadcast from the Anthorn radio station near Anthorn, Cumbria which serves as the United Kingdom's national time reference. The time signal is derived from three atomic clocks installed at the transmitter site, and is based on time standards maintained by the UK's National Physical Laboratory (NPL) in Teddington. The service is provided by Babcock International (with which former providers VT Communications merged) under licence from the NPL and is funded by the Department for Innovation, Universities and Skills.
The signal, also known as the MSF signal (and formerly the Rugby clock) is broadcast at a highly-accurate frequency of 60 kHz and can be received throughout the UK, and in much of northern and western Europe. The signal’s carrier frequency is maintained at 60 kHz to within 2 parts in 1012, controlled by caesium atomic clocks at the radio station.
Its important for people to check which radio signal their alarm clock is tuned into. Virtually all radio controlled alarm clocks in the UK are automatically set to the NPL, however if you purchased a radio alarm clock from Germany, France, or most other European countries these would be tuned into their own national signal, so if you tried to use it in the UK, it would show the wrong time.
Radio controlled alarm clocks are available in many different styles, shapes, colours and designs, from traditional radio controlled alarm clocks to modern digital radio controlled alarm clocks. The main reason why people but these clocks is because they are reliable, accurate and the clock will set the time itself, leaving you rest assured that your alarm clock has the correct time and will awake you when its time to wake you up in the morning.
Most alarm clock makers have a range of radio controlled alarm clocks, companies like Acctim and the London Clock Co have a wide range of analogue and digital versions. A really popular radio controlled alarm clock is the Pulse radio controlled alarm clock. The Pulse digital alarm clock from Acctim is radio controlled for split second accuracy so it synchronises its time with the UK’s national time signal from Cumbria. It has a silver and black finish to it and a well laid out and smart digital display which makes ready the time easy and straightforward, it also displays calendar and indoor temperature. The alarm clock has the Smartlite technology which illuminates the display for easy night time viewing.

A lot of modern alarm clocks have the radio controlled feature built in however its important to double check as some people get confused with radio alarm clocks, which play radio music and does not necessarily set it’s own time accurately. In summary radio controlled alarm clocks make great accurate clocks that will wake you up on time every morning.
