The digital radio standard was initiated as a European research project in the 1980s. The Norwegian Broadcasting Corporation (NRK) launched the very first DAB channel in the world on June 1st 1995 and the BBC and SR launched their first DAB digital radio broadcasts in September 1995. Digital radio receivers have been available in many countries since the end of the nineties. Digital radio may offer more radio programmes over a specific spectrum than analogue FM radio. Digital is more robust with regard to noise and multipath fading for mobile listening, since digital radio reception quality first degrades rapidly when the signal strength falls below a critical threshold, whereas FM reception quality degrades slowly with the decreasing signal.
When manufacturers added an alarm clock feature to the digital radio is took the use of this great electronic device into the bedroom and has vastly improved the way people now perceive their alarm clock. Instead of getting stressed about the wake up alarm people can wake up to their favourite digital station or they can snooze back to sleep with the sound of soothing music. Virtually all digital clock radio alarms are powered by the mains electricity, so they are ideal to plug into your bedroom and sit on your bedside cabinet. These devices tend to be more expensive that alarm radios with just FM and AM receivers as they use more technology.
Most of the devices have extremely easy to read digital LED or LCD digital displays, the LED displays are normally red, or even green and the LCD displays are grey/black, virtually all models have built in backlights for easy night reading and also a handy snooze feature when the alarm clock radio turns on in the morning.
Most people are prepared to spend that bit of extra money to get the digital clock radio alarm they want, normally as the price increases so does the quality of the device gets better, with improved electronics and also extra features. Some of the most expensive versions can be a couple of hundred pounds with basic versions on the market available for around £50 pounds. If you buy your digital clock radio alarm abroad you need to check if it picks up the UK’s digital radio stations and is not set for a foreign country. One of the most popular and feature rich range can be found from Roberts, an example is there Digital radio Clock alarm, which can pick up hundreds of digital stations in the UK with great sound quality and an accurate and reliable alarm to wake up to in the morning.
