Chris: The Northern Ireland Mini-Multiplex that will carry RT will come on air at the completion of switchover on 24th October.

Brian: There has been engineering works in preparation for switchover.
Don't retune if you have difficulties as these won't be caused or resolved by retuning and you may end up loosing affected channels from your receiver altogether.

Jill, it would be better if you left your own postcode, but from one I found in Ballynahinch then you should be able to pick up the NI mux after switchover - Postcode Checker - Detailed View
However you will need Freeview HD equipment to get RTE.

According to the Postcode checker at
Postcode Checker - Detailed View
Black Mountain (very close to Divis) will transmit the special NI Mux on channel 37 at 2kW from 24 October 2012. This Mux carries RTE1, RTE2 and TG4 - however it is likely rights restrictions will prevent some sports coverage from being transmitted (BT808NU)
