Hi,
BT19 7XS, aerial on roof
I've been having issues with the ARQ-A channels for the past week or so. Tried various troubleshooting steps but they're still pixelated and unwatchable. Up until then the channels worked perfectly with no issues. They are still working on a TV in the next room. No issues with any other channels (although BBCA has started being spotty this evening). A
I see there was planned engineering on Divis starting 27/11, could this be the cause? Is there an estimated end date? Not sure what else to try save getting someone out to look at the aerial.
