UK Radio Frequently asked questions

This section contains answers to questions commonly asked by visitors to this site. If your question isn't answered here, please post it to our visit our forum, and we'll try to help.


How do radio stations know who's listening? Both the commercial radio and BBC radio stations use a body called RAJAR to conduct independent research. This is normally done by RAJAR representatives handing out diaries on a door-to-door basis during sampling periods. Listeners mark in the diary which station they listen to, and RAJAR compile the results, informing stations of the ratings. Ratings are collated four times a year.
For details, see www.rajar.co.uk

How do stations get their Travel news? Local radio source their travel news in several ways, but most commonly, they'll make use of the services of one of the dedicated companies that provide voice and text reports to radio stations: Until recently, AA Roadwatch was probably the best known of the companies providing travel information, but changes announced in late 2004 means that their role is to be reduced (see Times News Story). This leaves Trafficlink as the prime source in the UK.
Some stations have their own in-house travel staff as well, to add a local voice to reports. Travel is gathered from various sources, including: local police, motorway control, rail companies, courier/taxi firms, listener "jamlines", and spotter planes.
The 2015 FM Switchoff?

The Digital Britain report published in June 2009 talks about a "Digital Radio Upgrade" plan to be complete by the end of 2015. This would involve existing FM and AM statiions moving to D.A.B by 2015, and the space on the FM band being used for low-powered community radio stations.

More details on the FM Switchoff on our FM Radio page.

How do stations keep their clocks accurate? Radio stations use radio-controlled clocks that are synchronised to atomic clocks via the MSF time signal. It's now possible to buy such clocks for use in the home for under £10. See our section on radio-controlled time for more information.

DAB vs Digital TV?

A common area of confusion. in the last few years, a host of new "digital" radio stations have appeared. There is common confusion over what exactly "digital" stations are, and where you can find them. The following all class as digital stations:

  • Watching radio on your TVStations that broadcast on audio channels of Sky and Freeview (such as BBC1Xtra and BBC Radio 7). You can listen to these through your TV speaker, and connect the output from your set-top box to a Hi-fi system if required. For a list of radio channels on Sky, click here. For more on Freeview's radio services, click here
  • Stations that broadcast on DAB - Digital radio that can be picked up with a special DAB receiver. Portable, in-car and hi-fi DAB receivers are available. For more on DAB, click here.
  • Stations that broadcast on the Internet. Streaming audio to your PC via an internet connection. For more on Internet radio, click here.

Some stations broadcast on all of these formats, including the new national radio services from the BBC. If you're looking for more radio choice, you may find that the station you're looking for is available on all of the three options, otherwise consider whether listening to radio through your TV suits your requirements, or whether a portable DAB receiver more suits your needs.

Radio listings Looking for listings of upcoming radio programmes? Try a powerful listings program for your PC, mobile phone or pocket computer. Listings are uploaded over the Internet. The advantages are: searchable, cheap, greater listings, configurable. See our dedicated TV and Radio guides page

Distant stations

What happens if you want to listen to a specific station, but you're out of the area? Suppose you're a fan of a local radio station, then you move away from the area... or perhaps you want to listen to a local station from work... maybe you've even moved countries and want to keep in touch with news from your home town... There are a few options to try:

  • Internet Radio - More and more stations offer a streaming radio service - with their signal being available over the Internet. To receive these, you need an Internet connection (preferably Broadband). Go to the station's website and see if they offer a Listen Live service. If you prefer to listen on something radio-shaped, and not your PC - try something like a BT Voyager or a Wi-fi Internet radio - More on our Internet Radio page
  • Digital TV - An awful lot of radio stations (including many local stations) are available on the digital TV platform - The widest choice is available on Sky Digital, including the BBC regional stations, Heart 106.2 (0124), BBC London (0152), LBC (0177), Spectrum (0185) and RTE (0160). Freeview and cable providers also offer radio stations - See our Digital TV page for the options
  • Get a good aerial - If you're only a little out of the area, a local aerial contractor may be able to fit a directional FM aerial, pointing directly at the station's transmitter. If you want to Do-It-Yourself, you'll find what you need at Maplin Electronics

Can I use my UK DAB receiver overseas? The UK uses Band III (Band 3), while other parts of the world use the lower-performance L Band (1452-1490MHz). The UK may be extended to cover L Band in the future (a recent report states that this may happen by 2007). Most DAB radios available to the UK support Band III only, although some receivers for both Band III/L Band are expected to be released in 2003. If in doubt, check the manufacturers website. For details of which countries use Band III and L Band, see the DAB Ensembles site. Note that we're not aware of any UK stations being transmitted overseas on DAB. Worldwide travellers may still be better off with shortwave or satellite services to receive UK stations abroad. If you can add anything to this section, please let us know.
For more on DAB digital radio, see our DAB page.

Radio on your PC? If you're looking to listen or record radio onto your PC, you'll need an internal card or an external USB receiver. Note that a Freeview TV card or USB box can also receive radio stations, and offers both radio and TV for your PC - worth a look.

For more on listening and recording radio on your PC, see our Radio on your PC page.

Internet radio? Thanks to the Internet, you can now tune in to radio stations from around the country and around the world over the Internet. Get yourself a broadband connection, and there's a host of radio stations to choose - you can even start your own for next to nothing.
BT Internet Radio
For more, see our Internet Radio page, or consider getting a BT Internet Radio

Then there's also the new form of broadcasting, known as Podcasting

See our Mobile Audio page

Music copyright

If you know a little about music copyright, you may now that each time a piece of music is played to an audience, a royalty payment is due. In the UK, there are three main bodies that are responsible for collecting royalty fees from radio stations and apportioning the money to their members. They are as follows:

  • PRS (Performing Right Society). Body that collects royalties in respect of music played by radio stations for artists and composers. More details at www.prs.co.uk
  • PPL (Phonographic Performance Ltd). Body that collects royalties in respect of music played by radio stations on behalf of record companies. See www.ppluk.com
  • MCPS (Mechanical Copyright Protection Society). Body that collects royalties in respect of music played by radio stations, specifically jingles and music used in adverts. See www.mcps.co.uk

Most music radio stations own a 'blanket' licence, that allows them to play whatever music they wish, in return for an annual licence fee (based on audience size and revenue). To allow the likes of PRS to apportion the revenue, PRS ask each station to return a detailed summary on what was broadcast, via a series of random "sampling periods", where all music played including jingles, advert music, and even the presenter singing, gets logged and returned to PRS for analysis.

What was that song?

If you've heard a song but don't know the title or artist, there is a service out there that may be of use. Shazam allows you to dial a number from your mobile, hold the mobile so it can hear the track, and then get the information on title and artist back as a text message. The fastkey number is 2580, and you can find more details on this service at www.shazam.com

Once you have a title and/or artist - try Amazon to order the CD, or download the song legally with napster.co.uk . (over 1 million tracks available!)

How do I start my own radio station?

We quite often get asked what's involved in setting up a radio station in the UK (legally), so here's a few considerations:

  • Licensing - UK commercial radio stations are regulated by OfCom. If you want to run a radio station, you need to get a broadcasting licence from OfCom. This includes FM, AM, community, restricted-service and DAB digital stations. For more on licensing, see http://www.ofcom.org.uk/radio/ifi/
  • Technical - You have to have a technical plan in place to get your signal broadcast. For FM and AM stations, you need a transmitter - Two firms can help: Arqiva (formerly NTL Broadcast) and National Grid Wireless (formerly BBC/Crown Castle). Those looking to broadcast on DAB will need to reach an agreement with a Multiplex operator covering the required area. If you want to broadcast on Sky, you'll need to negotiate for space on their satellite transponder. Ofcom offers some guidance on this on their website .
  • Business plan - To run a radio station, you need a sound business plan to make sure that you can pay the bills, recoup the setup costs, and generate revenue.
  • Music - To broadcast music, you'll need to reach agreement with the UK copyright bodies PRS, PPL and MCPS - see above
  • Costs - Vary depending on the type of station and the length of the licence period. Costs include transmitter rental, music copyright licence, broadcast licence, premises, studio equipment, broadcast circuits, promotion budgets and staff costs, as well as the standard costs of running a business.

The above gives a general idea of what's involved in setting up a UK station. There are a couple of books on the subject, which may be worth considering. The Ofcom site also carries information on the licensing process and what's involved. For non-UK stations, contact the appropriate regulator in your country for guidance.

Another option open to you, is to consider broadcasting on the Internet - to get started, all you need is a PC and an Internet connection. We have some information on how to set up an online radio station over on our Internet Radio page.
You could also consider creating a podcast - see our DIY Podcast section for notes on how to get started as a podcaster.

Why is there a time lag with digital radio?

One of the slightly annoying things you may notice about digital radio and TV, is that there's a slight time delay in the digital transmissions - sometimes up to a couple of seconds. This can be a pain if you are listening to a digital service with an analogue service in another room,or you're using the BBC pips to set your watch.

The delay is due to the way channels are combined together (multiplexed) and compressed - it's one of the limitations of having a system that can squeeze loads of channels onto a single frequency. Your digital radio is receiving the encoded and compressed signals and using an onboard microprocessor to decode the incoming data and convert to audio - something that doesn't happen with standard analogue TV.

Satellite listeners note that there's also the delay of a round-trip to the satellite and back (Typical delay is 900ms and 2200ms, depending on the data encoding/decoding used, and allowing for the 72,000 kilometre journey)
