Since Christmas there have been at least three occasions when we have switched on our television set only to see the message "no or scrambled signal".This seems to be happening more and more-can you explain?

LONG MOUNTAIN transmitter - Freeview BBC Digital TV Off Air from 22:05 yesterday to 22:21 yesterday [BBC]

Jackie: The channels you get depends on the direction your aerial points (and also the group of the aerial if it not the wideband type).
However, you are not predicted to be able to receive any additional channels this way. You may need to add Freesat to your system - see All about Freesat | ukfree.tv - independent free digital TV advice .

Roger Callow:
These outages have been occurring ever since LM switched to DVB-T in 2009, but they've been getting more and more frequent. Both MUXes still get broadcast, but they carry no data or programmes. Sometimes one MUX goes blank, sometimes the other, and relatively infrequently both go blank. I've confirmed this on multiple pieces of equipment off two separate aerials.

Very interesting.Long Mountain gets its feed from parent transmitter,Blaenplwyf via a microwave link at Llangurig,just wondering whether this is cause of outages.Also are the dependant relays of LM,such as Llandinam affected by these breaks in service.Certainly not a good advert for digital advancement!

OK Briantist,lets put it this way,if the punters are watching TV,and then experiencing breaks in service,as they might do using LM Transmitter,then i imagine it is a very frustrating time,particularly in the middle of a favourite programme.As an analogue transmitter did LM experience the same problems? i think not.

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.
