elaine: From Wednesday (24th October 2012) UTV, C5 etc will be carried on Mux D3+4 at 100kW. This is an increase in power from the present 2.3kW on Mux2. You should have much improved reception from then.

KDM: As with my post above to elaine, following DSO stage 2 on Wednesday 24th October 2012, when the Divis PSB muxes will all radiate at 100kW and the COM muxes will be at 50kW you should notice a considerable improvement in reception. At present some receivers do not perform well on the low power transmissions due to the presence of the high power Mux BBCA.

George Buchanan: Well, yes, the owners of the commercial multiplexes base the economics on the cost of providing and running a transmitter in relation to the number of listeners (or viewers for tv) which are served by the transmitter. The extra transmitters for local multiplexes being built as part of the commitment to an FM switch-off serve populations which are considered too small to be viable in economic terms, so an agreement has been reached whereby the cost of providing these transmitters is shared between the commercial radio stations, the BBC and the government. Hence, in part, why the MXR multiplexes are to close and the 'savings' put into running the extra local multiplexes.

Steve: If BBC1 SE is giving reliable reception but the other BBC channels are poor it shows that you are receiving signals from two or more transmitters, your receiver decides to store the first option found rather than the best quality signal for those channels that have identical content from the available transmitters. If your aerial is pointing to Whitehawk Hill clear the channel list, then do a manual tune for each of the Whitehawk frequencies C60-_, C53, C57, C56, C48 and C51(HD)if required. If manual tuning is not possible commence the channel scan with the aerial unplugged, missing out the weaker signals on the lower frequencies, then plug it in before C48 to store all the Whitehawk Hill frequencies.

jerry: You need a Freeview box that supports MPEG4 to receive a picture on RTE. Either a BT vision box or a Freeview HD box would be suitable, otherwise a use Saorview box.

Fergus Maunsell: Your TV appears to be listed as "HD ready" which means that it is ready to display a HD picture when fed via the HDMI connection with a suitable HD source, such as a Freeview HD box, HD satellite box or blu-ray player. You need a Freeview HD box (or receiver with in-built tuner which supports DVB-T2) to receive both the Freeview HD channels from Divis and the NIMM from Black Mountain.

Steve: Not only Holme Moss missing. Other important BBC transmitters were Kirk o'Shotts, Ashkirk, Meldrum, Thrumster, Fort William, Orkney, Morecambe Bay, Peterborough, Manningtree, Swingate and Les Platons. For the IBA there were St Hilary, Mendlesham, Chillerton Down, Richmond Hill and Membury. I have not mentioned a few low power relays that were also missing.

Cee: You need to use either a Saorview box or Freeview HD box to receive a picture on the RTE channels. This is because Saorview uses the MPEG4 video format, unlike standard definition Freeview which is only MPEG2.

Mark: You need to try an aerial pointing directly at Clermont Carn, preferably a group B for best signal pick up of C52. If your present aerial is a group A for the Divis frequencies it will not be very effective at receiving anything over about C40. Even if it is a wideband type, the angle between Divis and Clermont Carn will probably cause you to lose quite a lot of the available signal from Clermont Carn.

Jacke: If you are referring to satellite reception of BBC4, the transmission has moved to transponder 45 on Astra 1N.
