I believe they have a radar screen for situational awareness but are not allowed to use it.I used them that day whilst outbound on 124.6 as far as the boundary but on the way back from Ostend was totally unable to raise them at 2500 feet. They were very busy and possibly bandboxing as I could hear aircraft talking to then as far away as Enniskillen and St Athan.I like to use them but it never worries me if I can,t raise them.Much better service from the units on the other side of the channel.Regards Stampe.
