Since the callsign "London Radar" is already taken. What will they call themselves? If they are going with the river motif (a la "Thames Radar") how about "Lea Radar" for the bit north of the Thames and "Mole Radar" for the bit to the south????!!!!!!
Or we could resurrect some names from the past "Kent" and "Bedford" perhaps??
G W-H
(Just been to the pub - full of good ideas!!)
