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?

Brian!

I sent you a private email regarding this matter. I included correspondence I had with NVTV regarding the re-launch date. This station was on the air in analogue up to DSO from a local transmitter in north-west Belfast.

They (NVTV) had to start to raise the money required to pay the transmission fees to Arqiva I am lead to believe.

Haven't heard that one KMJ. September 2013 was supposed to be the original start date, and Thursday was widely publicised as the revised one.

Disappointed it didn't appear but not really surprised. Can't say I'm optimistic about September 2014 either, given the nature of these things.

Indeed Kieran, I could receive it over at my parent's house in East Belfast but no sign of it on analogue at this location. Channel 33 is mostly receivable but it does break up on occasions.

From what I saw, the programmes on NVTV were actually quite good and much better than their radio station when it was on air a few years back.
