Ed Thompson: Did you a "first time retune" at switchover? Switchover ends in Berkshire and North Hampshire

Alan wardle: 4G tranmitters will probably be on 3G locations - see http://www.sitefinder.ofc….uk/ .

Angela: I presume you have a FreeSAT box, rather than FreeVIEW - if so the postcodes are provided to the set-top box by the satellite signal, so it could be that the dish is not aligned to the correct satellites.

Dave Lindsay: Quickly looking at the maths from
Bit Rate Calculation for COFDM Modulation
A=54E6 * (packet length/204) = 54E6 * 1
B=A*Bandwidth= 54E6 * 1 = 54E6
C=B*modulation scheme (16QAM=0.5) = 27
D=C*code rate = 216 * .5 = 13.5E6
E=D*guard interval value = 13.5E6 * (128/129) = 13395349
So the bitrate for the multiplex is 12.77Mbps, which probably explains why the services will be SD and you can't really get more than one HD service in 12.77Mbps.
