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?

Hi all!

I was just rescanning UHF 30 which carries the LBT from . I am aware that Northern Visions TV (NVTV) will not be on-air until about September 2014 - due to my understanding funding issues. When it does come on-air it will occupy the No: 8 position on the Electronic Programme Guide (EPG). BonanzaBonanza is also carried on this UHF channel EPG position 64. Along with BonanzaBonanza I am receiving another - POP. My understanding is that this station is only available via - Am I right or have I missed the News regarding this station. I receive it on EPG position 791 as a TV station.

Regards
