It costs nothing to join and only takes a few minutes. We have 200,000 different people visiting our site monthly and this amount of motorhomers in one place guarantees a fast response to any questions you may have. We also have unique facilities not found elsewhere such as our Online Logbook, stopover tracker, Motorhome directory with Ebay type feedback and the largest repository of motorhome campsites reviews found anywhere
I have been maintaining a spread sheet of the location and status of cutover of the UK's main TV transmitters from analogue to digital. I keep this in a CSV format for loading into the Ordinance Survey maps of the British Isles from Memory Map. The spreadsheet is attatched as a download along with the icons I use. It is up to date as of today. It may be of interest to other members?
Whilst it is in a format to load into my mapping on my laptop, those with the know how may like to change it for loading into other formats for their mapping systems.
I use it like this:
Once loaded into my mapping I can at a glance see where the nearest TV transmitter is from where I am parked and what is the best signal to receive, analogue or digital. Using my GPS bluetooth mouse linked up to this mapping I can also establish the magnetic bearing to this transmitter. It then becomes a simple exercise to point a directional aerial very accurately for the best reception. You would be amazed at how different this often is from other aerials on the same site!
If this is of use to anyone, I also have a spread sheet of all the repeater sites but I am not sure with all the changes over the last few years how up to date this is so I have not attached this but if required I can make this available as well.
With thanks to Spykal for the original positioning information.

Peedee,
I commend you for finding the time to do this. However, it only lists 68 of the over 700 transmitters including Relays. It also lists those Main Transmitters that have not yet gone through switchover as Analogue although they are currently transmitting Analogue and Digital at the same time.
It also lists, for example Oxford, which is currently at DSO1 and will be at DSO2 next Wednesday.

It was spykal (Mike) who provided the basic information. All I have done is tailored and updated it for my own use with the goal of mapping all the areas which have fully completed switchover. For me this creates a useful resource for accurately setting up of digital terrestial TV reception where a directional aerial is used. Not everyone will have the mapping and equipment to find it useful but as I already had it, I took the opportunity to utilise it further. As stated above I do have a csv file of all the locations of repeaters (relays) but with so many of them I have not bothered to keep track of what has or is happening to them during switch over. I only consider their use if signals from a main transmitter are no good.

Peedee,
I am not trying to knock your efforts, they are highly commendable. However, it is the relays and the ongoing switchover that will cause the many complex issues of overlaps within the next week and for the remainder of switchover.
There is also the issue that many of the main transmitters switching later this year and next are not omnidirectional. Some, Guildford for example have a complex beam pattern designed to minimise the impact of overlaps in heavily populated areas. In other areas some relays will transmit dual regional programming to satisfy historical news boundaries.
There will be many households or pockets in the Country that are likely to be able to tune to up to 10 transmitters from the same location, and next week with the completion of DSO2 at Oxford some locations will see 7 transmitters.
The next 12 months will see a very complex stage in switchover with many transmitters facing up to 8 retunes as they switch frequencies to clear channels for others and also to fit in with the requirements of mainland Europe and Northern reland.
As an example, Sandy in Beds will have to go low power on one Mux to allow Bluebell Hill in Kent to power up on the same channel whilst it waits for Dover to clear the final resting channel. Dover cannot complete its channel resting places as it is waiting for Calais to finish. Calais in turn cannot complete due to changes in Belgium and Holland.
To say that there are serious concerns within the industry is an understatement.

This is the only site with mapping based on actual transmitter footprints. The Freeview postcode checker runs from the back of this site.

Blimey! I thought I was lucky in having a choice of 3 main transmitters using a wideband aerial http://www.digitaluk.co.uk/ is the site I have been using to keep my information up todate.
For the motorhomer, and even a household, sounds like we would all be better off with Freesat!
