4.2.7Types of Receivers

A selection of DAB digital radios has been on the market since 1999 in models for the home, the car and the PC. Handheld radios also entered the market in 2003 with competitively priced models for radio listeners on the move. Stations can also be accessed using a PC equipped with a suitable receiver/decoder card.

Availability of DAB digital radios varies from country to country where DAB is available. Department stores, independent retailers, supermarkets and multiples in most major cities in the UK carry a wide range of receivers representing a mature retailer market scenario. In the UK there are nearly 150 products in the market rising to around 200 products by the end of 2005. In Germany, Belgium, Nordic countries and Singapore, DAB is becoming available via specialist stores, independent retailers and some department stores in small quantities, and in Italy through manufacturers’ catalogues. In Spain and France, receivers can be ordered and delivered on demand.

Prices of digital radios were high at first, but as with most new technologies, over time, prices have fallen dramatically. Receiver prices vary from country to country, so it is impractical to present specific price points within this guide. However, DAB digital radios can now be found retailing from €60. A price guide is available from the WorldDAB Project Office, on request, on the WorldDAB website, www.worlddab.org/dabprod.aspx.

Models delivering additional features have also been developed, with rewind, pause, record functionality and Electronic Programme Guide (EPG) already integrated in some models.
