In the years before DSO, LM did suffer from various outages, but typically only one of the channels would vanish at any one time -- the carrier would stop broadcasting. However, it was pretty infrequent, and nothing like as often as the outages post-DSO. As for whether or not it's unique to LM or whether any of the relays (or any of Blaenplwyf's other relays) suffer the same problem, I've no idea.

aerialman: It doesn't really matter what you "think not", does it? What matter is how it is done now.

Briantist, with due respect, we don't think we've identified a problem, we have identified one or more problems. Aerialman is right, LM was far more reliable pre-DSO than it has been post-DSO. As for reporting it to BBC Reception, yes, done that, made no difference. It must go to dev/null on their server.

Richard Jones: Well, that's the official reporting point. If you don't wish to use it, there is no other way.

It's not a case of not wishing to use it, I would use it if it made any difference, and have used it, but typically either they don't reply, or they do in their patronising manner, but the end result is the same: nothings gets actioned. It can't have, as we're still stuck with the problem over a year later. I also post about this to the uk.tech.broadcast newsgroup hoping that someone from Arqiva reads it. It's Arqiva who need a swift kick up the rear end.

Yes, that's broken or just gets ignored. As such, it may as well not exist. Meanwhile, outages still continue...

I imagine,that Arqiva are more than aware of the problem,and maybe even looking at a resolution,and have in the past had many a constuctive conversation with them over various issues, more than i could ever say for the old NGW regime!
I can only repeat,Briantist,if you were watching from this transmitter,with all the outages which are taking place to annoy the viewer,you might not have such 'a sweep it under the carpet attitude'
