Gill Lyons: The power of the transmitter for the SDN mux was increased slightly at switchover, but changes to the technical parameters could have resulted in a net decrease of effective coverage. If you have a manual tune facility select C41, then without scanning/storing channels note the signal strength and quality indicated. Does that differ significantly to that indicated for say C44?

Gill Lyons: The rest of the post, which got cut off reads: If it is indicated that the signal strength is just below the threshold for reliable reception, with reasonable quality, you could try amplifying the signal. It is possible that the aerial is positioned in a null for C41; if signal strength for the other muxes is noticeably higher it would support that suggestion, in which case having the aerial repositioned could be of benefit. Also check cables and connectors are in good order and try repositioning connecting leads in relation to the receiver in case there is any interaction present causing the signal on C41 to be corrupted.

Susan Hopkinson: If you stop paying your Sky subscription you will still receive "Freesat from Sky" channels, that is all those which are not tied to a Sky package. Removing your card temporarily will reveal which channels you will continue to receive via satellite. With regard to your in-built Freeview, with an aerial pointing to Dog Hill you should be able to receive all the BBC TV and national radio channels plus ITV1&2, C4, C5, More4, E4 and ITV1+1, C4+1. If you are able to have an aerial pointing to Winter Hill you are predicted to be able to receive the full Freeview service, this being subject to there being no trees or tall buildings blocking the signal.

Carl: transmitting in HD is more expensive than SD, hence on satellite many commercial broadcasters choose to charge a subscription to view HD services. This is also the case in Germany. It is worth noting that NHK chose to close its SD service, and now transmits free to air in HD only. Such a move by other broadcasters would, at the present time, leave many viewers who have SD only receivers unable to view the channels.

Tony Hill: The available HD channels are identical on Freesat and Freesat-from-Sky. It is really only worth buying Freesat equipment if a PVR is required, otherwise staying with what you already have is a no-cost option. When funds are not limited I would personally opt for a generic satellite receiver that supports Diseqc and use a dish fitted with a second LNB in order to receive some real alternative to a multitude of shopping channels!

michael o,neill: The best course of action would have been to ask the landlord or building management company responsible for the communal aerial if it was possible for the aerial to be changed to Sandy Heath in order to receive the missing three COM muxes. As this is an issue affecting all the tenants, if they are using Freeview they would welcome such a change. Regarding the Freesat box, as a connection to a dish was required there should be clear indication in your tenancy agreement if a satellite connection is provided through the communal aerial and if an additional charge is made to make use of it.

kath clements: A build up of snow on an ordinary aerial can reduce the signal to a "no signal" level in the same way as it can on a satellite dish. Normal service is resumed when the snow melts (or is brushed) off.

KM: Do the missing HD channels appear in the 800s as working channels? If they do, a factory reset will be necessary to clear the memory of the original data in the LCN positions before scanning for channels.

Corofin: BBCA from Mendip moves to C49 on 27th March 2013. The change shown in 2018 is from an Arqiva suggested plan for freeing up further spectrum.

linsey: It is worth checking that your receiver is tuned to the transmitter that the aerial is pointing to. If your aerial is mounted with the rods vertical it is intended to receive from Brierley Hill, if rods are horizontal it is intended to receive from Sutton Coldfield. Both transmitters are in the same direction (53 degrees or NEish), so incorrect tuning is a possibility. Have a look at the frequency/channel being received for each of the muxes. B/H is 60-, 57+, 50, 59+, 55 and 53(HD). For S/C the UHF channels are 43, 46, 42, 45, 39+ and 40+(HD). These correspond to muxes carrying BBC1, ITV1, ITV3, Sky News and Film4 respectively.
