I've just put a quick page up at

http://jcgl.orpheusweb.co.uk/temp/dttv.html

This is to show the results I've produced having obtained a set of data for
the current UK DTTV TXs and the changes intended for 4G. I'll write the
blurb later on, but thought some people would find the maps of interest.

I've posted this message to rec.audio as well as digital-tv because of the
relevance to audio (i.e. sound radio) listeners. A year or two ago I did
similar maps for DAB and VHF. But at that time I didn't have the matching
TX data for DTTV. And of course if 4G upsets DTTV reception anyone wanting
to use DTTV for sound radio will be affected!

There are three PNG maps on the page. One simply shows all the TXs above
100W EIRP. The second shows which ones will be changed to clear space for
4G. The third shows the ones which will - if things go to OfCom's cunning
plan - use ch59 and/or 60 when the clearance is done. These second maps
extend down to lower powers.

Note that the sizes of the circles DO NOT show the coverage areas! The
diameters of the circles simply indicate the TX nominal ERPs. The idea is
just to show where main/high-power TXs are affected, and where lower power
ones are involved.

Slainte,

Jim
