Tim Johns, a producer on Radio 2, tweeted: “Oh dear - there's a current problem with BBC DAB reception in central London. You may need to check that all parts of your receiving system are fully earthed. For more information on interference, please see our RTIS site. A qualified aerial installer with local knowledge will be able to advise further. If you know your location, you can use our, If you are having continuous reception problems. Check whether any of these is being used when you experience the problem. If there is a problem with one of the transmitters you can receive, you may start to hear burbling noises or break up as there may now not be enough signals for good reception. Timing can be random, or there could be a pattern if the lights are on a timer. If you can still receive radio stations via digital television this doesn’t mean that DAB radio is working—radio stations use a different technology to broadcast on digital television than DAB. If the transmitter is on reduced power or undergoing any transmitter maintenance work, this can cause hissing or fading. Note when the nearby lamps switch on and off and compare it with when you experience the problem. They come in a variety of powers; in most cases a small reduction is all that is needed. It may be necessary to call someone to give your installation a health check. There is a very small chance that 4G signals will affect your television reception as they use frequencies that are close to those used by Freeview television. This is normally the BBC Radio Leeds medium wave frequency. Distortion - fuzzy, gritty, scratchy sound. This needs to be rotated to find the best signal. It is sometimes possible to hear distorted speech through your TV loudspeaker or radio. For example you receive one signal directly from the transmitter and another is being reflected off a nearby hill. If you live close to a transmitter or can get a strong TV signal, then it could be possible to use an aerial in your loft or an indoor portable aerial. For more information on how to retune manually see our, If you are still having problems, it is possible an unwanted signal is the cause. Street lamps can sometimes cause buzzing and crackling sounds. The problem could be due to a number of reasons, the station may have stopped broadcasting or have moved multiplexes rather than a radio fault. There are all kinds of aerials available on the market and some which are specific to certain frequencies. For example, if water were to get into a masthead type, they can start to boost the result of the fault.
