When we began broadcasting to the Greater Norwich Area in September 2015, we operated our main DAB transmitter at a radiated power level of 100 Watts. Following discussions with the the UK broadcast radio regulator, Ofcom, it was agreed that this power level could be doubled to 200 Watts. After new equipment has been purchased and commissioned, we expect to begin transmitting at the higher power level early in 2016.
For copyright reasons, we aren’t allowed to publish our Ofcom coverage map, so (courtesy of Glyn Roylance at Associated Broadcast Consultants) here’s an alternative interactive version showing where you should be able to pick up our DAB transmissions once we’ve increased the power of our Markham Tower DAB Transmitter:

Green = 62 dBµV/m = Good indoor reception and strong mobile reception | |
Yellow = 54 dBµV/m = Limited indoor reception and adequate mobile reception. | |
Note: | In Yellow areas domestic receivers may need aerial fully extended / more carefully positioned. |
