Hi Edward!

While I live in North Belfast and I get most of my channels from Divis which I would say it is about 40+ miles from your location in a different direction, I haven't found any problem with signal strength or quality. It would appear that Arqiva are currently undertaking some work on the transmitter but this work appears to effect Radio Services only. The info provided by the BBC indicates that while there is still transmission of all radio channels - some are at a weaker strength than normal.

Regards

P. Kieran Ward
