I suspect that the BBC monitoring folks at Caversham might do something similar, only with a specific set, or sets, of frequencies. A quick search of the bbc web site gave only this, but I'm sure there's a lot more info on the BBC Monitoring Service if anyone cares to dig for it. http://www.bbc.co.uk/rd/milestones/1980s.html "Active steerable high frequency receiving array installed at Crowsley Park near Caversham for the BBC Monitoring Service." -- ....................paul It is important to realize that any lock can be picked with a big enough hammer. -- Sun System & Network Admin manual -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
