Charles Stuart: This is not unusual. Reception on an indoor aerial is often hit and miss,with each mux having the best signal in a differing location. Notice how an FM radio might receive different stations in different locations in the room. It is not always realised that in some locations even outdoor aerials have to be positioned in a compromise location to receive all the available muxes!

terence porter: Check for single frequency interference on or near C60. Also check your cables and connectors are in order and try changing the position of any HDMI cable.

Martin: You say the aerial is pointing towards Pembury, is it mounted with the rods vertical for the Pembury/Tunbridge Wells relay or is it pointing NNE with the rods horizontal for reception of Bluebell Hill? The reason I ask is because you are not currently predicted to receive signals from Pembury with any chance of reliable reception, whereas Bluebell Hill is shown as giving variable reception on the same frequencies that it shares with Tunbrige W. As you mentioned there is a power increase at Pembury on 22nd February 2012 after which a chance of reception (albeit poor) on muxes 1,2 and D is predicted, but this also muddies the waters for Bluebell Hill by causing a deterioration on shared frequencies. You are also predicted to have good reception from Dover (aerial horizontal and pointing E) but only on muxes 1, A and B, with MuxC variable, MuxD poor and no prediction at all for Mux2. Poor analogue reception does suggest possible reduced power working that has not been announced or either a problem with cables or connectors, an obsruction in the signal path (trees in leaf?) or the TV is tuned to a different transmitter to that which the aerial is pointing to.

Des Collier: Many people listened to radio Luxembourg through the night. Mind you it was totally different 50 years ago, children had bed times, pubs closed at 10.30pm, even the street lights went off at midnight. It was only night workers that didn't go to bed at least before 1am.

Briantist: Most BBC local stations finish "local" broadcasting at 7pm (unless there is a football match or other event to cover), a regional service takes over until 1am when 5 Live takes over until 5am. The idea that afternoon programming should be shared is not new as there used to be Afternoon Special, a very popular program which linked Derby, Nottingham, Leicester and Lincoln. I remember when Radio Derby started to do local broadcasting in that slot many listeners switched to Radio Nottingham, some even had FM aerials installed pointing to Nottingham in order to continue receiving the service! Personally I think Radio Derby, BBC East Midlands TV and commercial free Radio 1 are excellent value for money at less than £3 per week. As for local commercial radio, the rot set in when the regulators insisted on different outputs on FM and medium wave. The public service element from the original IBA model was put onto GEM AM which proved very popular, which I suspect was to the annoyance of the radio station owners who really wanted the flagship FM service to be popular. GEM then became part of Classic Gold, the local team of presenters moved to Saga 106.6 where the good work continued until Saga was bought by GMG who changed it to Smooth Radio and ended local broadcasting except for traffic news during drive time.

Surely the cost of providing the EPG should be shared out among all the channels appearing in it, at so much per channel. It should not be treated as a transmission levy as Sky do not incur transmission costs on other companies' channels. Sky could bear the cost of providing an EPG as a service to their customers, but that does not seem to be the way of working, not only at Sky but in telecommunications in general as custommers are charged large fees for services that cost little extra to provide.... example call baring on landline phones!

Steve: The CB10 postcode area covers quite a large area with regard to predicting reception, however it does lie in an overlap area between Sandy Heath and Crystal Palace which causes problems for reception of C31 in some locations. You did say that you were missing Sky News. This is carried on MuxC which is currently transmitted on C67. If there is no signal on C67 it is usually either a single frequency interference problem from an RF modulator set to C67/C68, or simply that being the highest frequency the losses in the cable and/or lower aerial gain at that frequency result in "no signal" at the receiver. Note that on 23rd November 2011 a retune will be required as from that date MuxC/ArqA will be transmitted on C52 at higher power and use 8k mode, so reception should improve on this mux.

Ian Grice: If everyone knew that 901, 902 etc gave the familiar BBC?ITV channels many people would go straight to 900 and skip everything before it.After all a Sky Sports fan does not work through every channel from 101!

Ceejay: Check for single frequency interference on C67, such as an RF modulator of a VCR or Sky box set to C67/C68.Also check cables and connectors. You are predicted (using the postcode of the local primary school as a reference) to have good reception on all muxes from Mendip.

Iona Price: Dont worry, there is a fault causing loss of transmission from Cwm Twrch and Ystalyfera. The BBC are aware that service was lost at 00.56, but no time is shown for expected resumption of service.
