 Hardly any of the receivers made before 2008 support the newer codec, however, making them partially obsolete once DAB+ broadcasts begin and completely obsolete once all MP2 encoded stations are gone.Most new receivers are both DAB and DAB+ compatible; however, the issue is exacerbated by some manufacturers disabling the DAB+ features on otherwise compatible radios to save on licensing fees when sold in countries without current DAB+ broadcasts.As DAB requires digital signal processing techniques to convert from the received digitally encoded signal to the analogue audio content, the complexity of the electronic circuitry required to do this is higher.
