I know. Airwave uses a separate mast. I go walking around that area quite a lot.

"Did you say that the problem used to happen to you analogue services in the past?"
Sometimes, but very infrequently. What used to happen was that the carrier would drop -- I'd know this because my VCR for a start would complain about it. Typically only one channel would go, I think BBC2 was the worst. The other three would carry on transmitting as normal and with no degradation of picture or audio quality. Video dropped off BBC1 one evening, but audio carried on as normal as if nothing happened. Again, confirmed on multiple piece of equipment off separate aerials.

Llangurig SHF: I've got something in the back of my mind trying to remind me about this, possibly a conversation I had with someone at Crown Castle some years ago. A dish not always in correct alignment? It was a long time ago, but something might pop back in my memory.
Touch wood, LM has been reliable since the major outage at the beginning of the year. That's not to say it hasn't happened again, but I haven't observed that it has.

I spoke too soon. PSB2 fell off air 18.41. PSB1 working fine. Digibox complains "No programme specific information," no Network or Provider showing up on Channel Information. Signal strength 25dB, 100%, Signal quality 0.00e+00 100%. Back on air 18:44.

PSB1 and PSB2 fell off air c. 14:45, about 25 minutes ago, and LM is not even broadcasting them as a blank carrier. Whatever frequency they broadcast at is just static. My Philips box is complaining "No signal. Please check antenna/cable", and same fault off all devices off both antennas here.

Back on air c. 20:30. Arqiva confirmed it was caused by a HV cable failure to the site. Why the backup generators didn't function, I've no idea. FM radio lasted until c. 16:30 before all that went off air also.

I had to resort to using www.tvcatchup.com to watch the first half of the rugby tonight. Not good. I may as well not have bothered anyway...

Friday's failure had nothing to do to with the method of transmission, but I don't recall such a long outage. I thought it was meant to be covered by backup generators? But this is a separate issue to the one of its unreliability post-DSO.

All five go off at the same time, and come back on the same time when the problem is resolved. I have 3 TVs, one fed off a Philips DVT-B box and sharing the same aerial with a Goodmans IDTV (the 80% signal device), and a Panasonic IDTV downstairs fed off a separate aerial. The problem usually lasts 5-10 mins or so, during which time I turn all three on, turn the volume up, tune to the same channel, and keep an eye and ear on them until the signal returns. It's fairly obvious when it does as I then hear each TV, and check I get a picture. I then turn off two I don't need, and carry on watching, usually on the old Ferguson while I do some PC time. As to times of day, I only notice it in the evenings and at night, as that's when I most typically watch TV, but it has happened during the day as well.
