Here is what I've heard in the last couple of month's at home on the West Sussex coast.

Receiver: Sony XDR-F1HD
Antenna: 3 element beam facing north.

87.5 Raw
90.6 Cyndicut
91.6 Genesis
92.6 The Rock
95.1 Origin
98.5 Code South (strong)
101.2 Unique
101.5 Empire
103.0 LDN Live
104.3 Cystal

Raw and Origin are currently the strongest, Crystal was previously the strongest from London until it went off.
