tony: There are several reasons why reception of the COM muxes from Rowridge on C22, C25 and C28 might not be possible in Bridport despite reception of the PSB muxes being ok. Firstly, with the aerial mounted for horizontal polarisation, the signal is only transmitted at 50kW horizontal, a quarter of the power of the PSB muxes. Additionally the same frequencies are used by Stockland Hill, the signals from which, despite being obstructed by local hills, are likely to cause interference to any signals from Rowridge. Secondly, the antenna for the SDN and Arqiva A&B COM muxes from Rowridge is lower down the mast than that used for the other services.The radiation pattern, which has not been made public could be tailored to limit interference to viewers to Stockland Hill. With the aerial mounted for vertical polarisation you might stand a better chance of reception from Rowridge as the COMs are 200kW vertical, however there is still the question of the radiation pattern possibly having a restriction towards Stockland Hill and the possibility of low level interference from S/H.

Stephen: Cullingworth was off air from 08.50 to 15.42 (from a BBC radio and television service check). If you were still wondering, Cullingworth is a direct relay of Emley Moor.

Darren: Most unlikely, since Sandy Heath only transmits horizontally polarised signals on each of the Freeview muxes. Sometimes raising or lowering the aerial, or moving it a short distance either side or backwards/forwards can make a significant improvement to the strengh of signal being received, albeit sometimes a case of improving the signal on one mux to the detriment of another!

trevorjharris: erm, just looked at the listings for Sky1 today, 22nd August 2014, all the programs are repeats!

Michael Simon: There is currently (August 2014) work taking place at Caradon Hill affecting the BBC local FM service and DAB transmissions. The reserve DAB antenna is a single dipole mounted below the BBC aperture, so it is likely that the strength of the DAB signal you are currently able to receive (or not!) is somewhat weaker than normal.

i garner: On the map used in Ofcom documents, Dartford is shown as being outside the area currently covered by the transmitters of the Kent local DAB mux. If and when this service is added (as is proposed) to the Wrotham mast, the signal is more likely to be available in Dartford.

D Mitchell: BBC South is only in SD at present. The English service of BBC1 HD does not yet have opt-outs for local news.

E.R.Bryan: What kind of receiver are you using to receive your TV channels? The numbers you mention apply to Sky then Freesat boxes. A generic satellite receiver will not use either of those epg positions. Likewise if you have a Freeview tuner and are able to receive signals from both Crystal Palace (for London) and Sudbury (Anglia) you will usually find London channels in the LCN positions of the channel list and East Anglia channels in the 800s. A tuner that only stores the variations will probably store Anglia at 800 and BBC1 East on 801 in the channel list ( as Anglia is found on C41 from Sudbury,before the BBC channels on C44) If the whole mux is stored the BBC channels will probably appear about 810.

Ian Fitter: Digital UK predict, correctly, that you should have Liverpool LM loud and clear.

Rog Parsons: RTE could not afford the increased costs for the rights to show material over the whole of the UK.
