As expected, and widely promoted to listeners ahead of the change, UCB (United Christian Broadcasters) have switched to using DAB+ for both UCB1 and UCB2. Both stations are now on the D1 National DAB multiplex, and are using 24 kbps DAB+ stereo (from 56 kbps Mono LSF for UCB1, and 64 kbps Mono LSF for UCB2).
As part of this, UCB2 moved from the SDL National multiplex, and has now gained wider coverage by being on the D1 National multiplex. However, this is at the expense of sound quality, and some DAB radios will not be able to receive both stations at all, due to not being DAB+ compatible. UCB2 was removed from the SDL National multiplex without any recorded re-tune loop advising listeners to retune.
With UCB relinquishing space on the SDL National multiplex, and reducing overall bitrates on D1 National by a further 8 kbps, this represents a significant cost saving for UCB. Also on the SDL National multiplex, Sunrise Radio (national/London station) have also reduced their bit rate, dropping from 64 kbps to 56 kbps (retaining mono LSF).
In a separate move that has also taken place relatively recently, the three national Jack Media services; Union Jack, Union Jack Dance, and Union Jack Rock, has left the SDL National DAB multiplex. All three services remain available online, and the local Oxfordshire services remain unaffected. The reason for this change is yet to be confirmed.
