Hello there, knowledgeable people! ^_^ I'm having a terrible problem with Freeview Reception and was wondering if anyone could confirm or deny that the Mendip Transmitter is having any engineering work done to it? After the slight channel change on the 28th of March when all the channels were set to full whack, we had perfect reception for a day or two (I forget how long exactly ^_^;) but after that day or two, like I said, our reception is terrible. Channels 54 & 48're not perfect but definitely the strongest, next is 52, and depending on the time of day 61 & 56 are unwatchable. I've noticed a few other people with similar problems so is it us, or is there something going in Mendip that we don't know about? Thanks for reading! ^_^

Dave, how I do I tell what transmitter a channel is tuned to? Is absence of info about this a limitation of different F.V. boxes?
My standard def. BBC1 (and its alright today) is indeed tuned to C61, but I'm not sure from which transmitter.
Thanks,
Ben

Ben Ward: C61 is that used by Mendip for BBC standard definition, so it is tuned to Mendip.

Ben Ward: The problem is that the relay transmitters retransmit the exact same datastream that they receive, it can't be subdivided. In fact to save costs, there are actually only 27 or so sets of Service Information, with even some main transmitters sharing the same information.
Therefore, a few years ago, the region descriptions changed from being the main transmitter in the Service Information region to being a rough geographical area. All of Mendip's relays, including the line-fed full Freeview transmitters at Bristol Ilchester Crescent and Bristol Kings Weston Hill, are simply described as 'West'. It was felt this was less confusing than signalling 'Mendip' when it might not be.
You can find the users of a specific channel by clicking the channel number in any post that mentions one, or in the list of pre/post-switchover channel numbers on a transmitter page - that gives you a map. It shows the pre-switchover state unless you clicked a channel in the 'After {switchover date} section. Or, you can go to Find a Freeview transmitter by frequency | ukfree.tv - independent free digital TV advice and click channel numbers to search.

Mike Dimmick: Is there a list available of the region names you refer to that transmitters identify themselves as?

Dave Lindsay: I became aware of the SIP Regions through the preparation of the 600 MHz band auction (that will not now go ahead), as one of the requirements for Single Frequency Network operation is that the transmitters sharing a frequency are part of the same SIP region. (SIP = Service Insertion Point.) The most recent planning document for that is at http://stakeholders.ofcom….pdf , and the SIP regions are listed in Appendix 5 (p50).
Since this was published, the BBC have decided to move Whitehawk Hill from the South to the South East region, and so it can no longer be a part of the Rowridge SIP region, but ITV have decided to keep it as Meridian South rather than move it to South East, so Whitehawk Hill (plus its relays) is now a region of its own.
I don't know of anywhere that lists the descriptions that are actually broadcast, though.

Mike Dimmick: Is the "600MHz Band Auction" that you say won't go ahead the auction of channels 31 to 37?
And if so, what will it be used for?

Yes, and if you look at the Transmission Frequencies towards the top of the transmitter pages you will see the channels allocated to additional commercial services COM7/8/9.

Street is close to the Mendip transmitter. Can you see the transmitter from your location?
Your postcode, put into the box on the top RHS of the page will help people to give more specific advice.

No, there are no known problems at the transmitter. As advised to Ed Stone, your postcode put in the box will enable more specific advice. Did you have any problems before this last change and power up?
