Paul Rice:

Further to that said by Amanda Hughenkis, look at the blue digitaluk trade box under your posting. That leads you to Coverage Checker - Detailed View which shows you are 7 km away from the Divis transmitter. Please ensure that your signal strength is between 60% and 85%, more will cause your problems.

BT7 3EE freeview channels disappeared and I had to re-tune. This wiped all my pre-recorded settings. I think fault happened about 11.13am today.

david: Keep It Country is on the COM7 multiplex which is not broadcast from Limavady.

Deirdre Kearney: Retuning is the worst thing to do if your channels disappear and is never recommended unless you have eliminated all other possible causes of the problem.

Carl READE:

Because they are the channels used to transmit the COM7 and COM8 multiplexes. Arqiva, who own and operate the transmitters, are providing some additional services on channels 55 and 56 on some of the main transmitters only. They are a temporary service whilst further frequency changes are being made to free up the 700 MHz band.
