The BBC map for BBC London 94.9 FM from Crystal Palace Map also shows the MF contour for the 50 kW Brookmans Park transmitter which is now used by independent radio (Sunrise etc)

IBA map for ILR Greater London (Capital Radio and LBC) VHF Transmitter is at Croydon and the map was drawn when this was rated at 2kW.  Power is now 4kW and coverage will be slightly wider (see below). Map can also be used to predict approximate coverage of other ILR services from Croydon i.e. 100MHz  102.2MHz  105.4MHz  106.2MHz though aerial patterns may be slightly different.

The above plot, done by RadioMobile, shows the predicted coverage of LBC and Capital Radio from the Croydon transmitter at the original 2kW (mixed pol') power in green,  and the predicted increase in coverage from the transmitter, shown in yellow, with the current radiated power of 4 kW (mixed pol')
