Please forgive me if these questions are elementry for someone more
fimilar with the BBC, but I've only recently moved to England.

Is there a method for determing what radio & TV stations are available
from a given lat/long (or, equivelently, National Grid reference)?  If
the best method is to compute it ourself from the list of transmitters,
is there a master list of all relevant transmitters?  The info under
http://www.bbc.co.uk/reception/transmitters may be sufficent, except the
local radio tables are in many cases malformed -- the tables have two
cells run together.

For reference, I list the tables that I'm aware of below:

Channel 5 transmitters -- very nice:

Map of TV 1-4 transmitters -- but no data table:
http://www.bbc.co.uk/reception/transmitters/tv_trans/index.shtml
MW/LW transmitters -- very nice:

FM transmitters, by country:

http://www.bbc.co.uk/reception/transmitters/radio_trans/scotland_fm.shtml
http://www.bbc.co.uk/reception/transmitters/radio_trans/england_fm.shtml
http://www.bbc.co.uk/reception/transmitters/radio_trans/wales_fm.shtml
Local radio -- but tables seem malformed:
http://www.bbc.co.uk/reception/transmitters/radio_trans/lr_al.shtml
http://www.bbc.co.uk/reception/transmitters/radio_trans/lr_mz.shtml

And, of course, there's an additional problem with using this
information -- the BBC terms of use prohibit using this information,
which is not a part of backstage.  Would it be permissible to use this
data regardless?  A one-time import would certianly suffice for this
data, which is not liable to change often -- and any changes I think are
likely to show up on the BBC news well ahead of them becomming live.

        Thank you,
