I've been working on this for the last few weeks and reckon it's now ready for a public "beta" viewing.

The aim of this collection is to pinpoint every broadcast radio and television transmitter in the British Isles (i.e. the U.K, Ireland and surrounding islands).

Sites are shown by either a yellow or red pushpin. Those that are yellow have been positively identified and the co-ordinates adjusted so that the pin appears next to the mast itself. Red pushpins indicate the site as given by NGR or lat/long but the mast has not (yet) been identified. This is either because the map is not high enough resolution or, in the case of minor relay transmitters, simply because I've not been able to find it in the picture!

I have plans to expand the collection to also include aeronautical VOR/DME beacons etc, maritime radio stations and military installations. Some of these are already present but this is definitely a work in progress. Also, there are currently very few entries for Ireland and I intend to concentrate on this in the next few weeks.

If anyone has corrections or additions, I would be very grateful to receive them and they will be incorporated in the collection as soon as possible.

I will in any case, be making updated versions available, as I add more sites.

15/8/07 - kmz file updated. Quite a lot more sites identified, mainly thanks to the additional hi-res google pictures.

A few more sites added as well.

Still need better pictures for Scotland, Ireland, IoM & CI before those areas can be done fully.

17/09/07 - another update. Quite a few Irish sites now but still more needed.

04/10/07 - another update. Now adding MF sites.

17/10/07 - another update. Should now include all BBC sites and a lot of ILR stuff. Also all Digital 1 dab sites. The Irish sites from the posting below are also included.

11/01/08 - a fairly major upgrade. Now includes all mf/lf broadcast sites, as well as FM, TV & DAB. Some aero VOR/DME beacons also added. Have confirmed locations for those parts of Wales, Scotland and Ireland that have received hi-res map updates recently. Will do more when the mapping allows.

30/01/08 - more updating. Only one or two broadcast sites added now as I really do think most are on there at last! Some main microwave sites (BT etc) added. The criteria for most is that they are large structures. There's no intention to add lots of mobile phone sites - just stuff that's interesting. A new pin colour (blue) has been introduced to indicate non-broadcast sites.

08/04/08 - more position updates because hi-res data for Wales is now available. A couple of new sites but this is more of a cosmetic update than anything.

15/05/08 - minor update only.

If there are any transmitter sites not included (of any type) please let me know!

Nigel.
