Jan 2015 New radio stations picked up on 87.6 & 87.8 Escape FM In Clacton Essex 87.6 seems to only stay on a short time then go off. Wonder if its a little car thingy some one is using close by? Though 87.8 has been playing dance and garage stuff last few days. Also citylockradio 89.4 is putting out a strong signal if from London the last few months.
