The symbol shows the location of the Divis (Northern Ireland) transmitter which serves 440,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Divis (Northern Ireland) mast?

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.

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.

Hi!
I reside in Belfast and my question relates to changes due to COM7 HD and COM8 HD. Currently I receive COM7 HD on UHF 33 and COM8 HD on UHF 34. There is a retune event due for both COM7 HD and COM8 HD on the 4th September 2019. This retune will move COM7 HD currently on UHF 33 to UHF 51 and COM8 HD currently on UHF 34 to UHF 60. A further retune event is planned for the period January to March 2020. In this retune COM7 HD will move to UHF 55 and COM8 HD to UHF 56. My interest in these retunes is; I currently receive Saorview from the RTE transmitter located Clermont Carn in North Co. Louth. They currently use two Multiplexes and they transmit on UHF 52 and UHF 56. Does anyone on UKFreeTV know what will happen to Saorview at the retune planned for the period January to March 2020?

Soarview have a plan, like Arqiva, to reallocate multiplexes to different channels as part of the 5G adjustments. They are working together to ensure that there is no interference between any channels.
At some stage, Soarview viewers will be required to retune as is happening with Freeview viewers.

MikeP: Well all I can say is it's going to be a disaster. I was out even today sorting out 4g issues and last week with customers years after it came in. Should never have been allowed in the first place.

4G uses parts of the spectrum that will not be used for digital television transmissions. The point us that these are being moved away from any 4G transmissions and sited below 700MHz where they should not be subject to interference from other transmissions. Surprisingly few people have had problems with the presence of 4G signals, especially those whose local transmitter uses the lower channels well below channel 60. Therefore there is no expectation of the disaster you fear.

Currently, no signal at this location from stations on Com 7 and Com 8 so I presume both multiplexes are off air.
Maybe some engineering work in preparation for next Wednesday's retune ?
