Lionel lewis: It is unfortunate that setups such as yours are falling fowl to the clearance of C61 to C68 for 4G services.
"If" Mendip's PSB1 (BBC One etc) had moved to a channel greater than 51 but one of the others which is available from Wenvoe was displaced to C49 then you would still be able to view BBC One West.

David:
It may be possible along the south and east Kent coast and just possibly along the East Sussex coast but it is unlikely to be receivable further west due to distance from the transmitters near the north coast of France.
I have no details of the locations nor transmission channels of their transmitters nor of the encoding or modulation methods used though they are likely to be similar to those used in the UK and I have to assume that they use same format standards as we do now. They used to use 819 line 50 field transmissions for many services in addition to 625 line 50 field, but that was all analogue and not digital.
How about doing a search for information on the internet and letting us all know?

I have just been told that in the near future BBC is only going to transmit in HD.
Is this correct please?
If so when is this to happen?

Bob F: Next year the BBC will broadcast all their services in HD, as well as SD.
Sometime between 2019 and 2025, it is expected that all broadcasts will be HD (DVB-T2), but this is "expected to be" rather than "official policy" at the moment.

Hi Briantist ,
Thank you for the HD services information.
I have just bought a 40" L1333 Full High Definition LED TV - Toshiba, but cannot get any HD programmes via Freeview from Mendip transmitter.
My post code is GL10 3BJ.
I tried a manual search of multiplex C58, but could find no signal.
What do I need to do to get the HD programs on 101, 102, 103 & 104 please?
I have the TV link to a Humax PVR 9300T hard drive recorder which was needed with my previous 15 year old analogue TV that has just died.
I can also receive Freeview directly from the boosted aerial type C/D E

Bob F: Your TV does not have the required Freeview HD / DVB-T2 tuner. See the "Tuning" section of 40" L1333 Full High Definition LED TV - Toshiba - it only has DVB-T.
