I am not interested in traffic information at all. I want to hear radio without interruption, especialy when I sit at home. How can I prevent traffic information interrupting my radio ?
MostRDS radios can receive short messages which might include informationabout the presenter, station or programme you are listening to. Forexample, BBC Radio 1's RadioTEXT always gives information about thepresenter and programme e.g. JOHN PEEL - TONIGHT IN SESSION.. ETC.., whereas Classic FM gives information which includes a web address for the station, e.g. CLASSIC FM ON THE WEB - WWW.CLASSICFM.COM.The information will usually scroll across the display on a home tuner,but this could be distracting to a driver in a car, so the RadioTEXTmessage in a car hi-fi does not scroll.
Theradio display can show if the station broadcasts travel information.Since most stations do anyway, this feature by itself is of limitedvalue. The Traffic Announcement (TA) feature allows interruption of aCD or cassette tape when there is a travel report from the radiostation that is currently tuned-in. The radio will automatically switchfrom CD or tape to the radio for the duration of the travelannouncement. Commercial radio stations willbroadcast three tones or 'bleeps' before and after the travel bulletin,but BBC radio stations do not need this. These DTMF tones are used whenthe transmitter (where the RDS inserter physically is) is locatedremotely from the studio, and for reasons of cost or practicality thereis no control path from the studio to the transmitter to tell thetransmitter when to switch on the TA flag. The only link from studio totransmitter is the station audio itself. Inthese situations, "in-band signalling" is used. A unit at thetransmitter site listens out for the DTMF tones in order to switch theTA flag on and off. The DTMF tones are recorded on the traffic jinglesto make life easier for the presenter. For the TA feature to work underany circumstances, however, the function marked TA, TI, TP or 'Traffic'must be switched on. It is possible to search out only those stations broadcasting the Traffic Programme on some radios.
