I would like to remind the Deputy, as I stated in previous answers to parliamentary questions in this House, that investigation of problems with the reception of RTE 1 and Network 2 is a matter for RTE in the first instance. RTE have the technical expertise and the local resources to investigate such complaints effectively. If, following those initial investigations, there is evidence of interference from another frequency spectrum user, RTE will inform my Department which then takes responsibility for the matter and liaises directly with RTE.
