Salisbury

A system retune has restored service to 'Film 4' and 'Yesterday' channels on one set, but with distorted and fragmented reception on another set (from a different aerial) within the same house. All other channels on this second set are working perfectly.

W L PENDER: What transmitter are you using?

Digital UK suggests Salisbury may be the best. However, Rowridge is also good and only 30 degrees away from Salisbury at your location.

My guess is that the TV with issues is tuned to Rowridge instead of Salisbury.

Fortunately Rowridge uses low channels and Salisbury high ones, so (if you are on Salisbury) then run the automatic tuning scan with the aerial unplugged up to 50% in order to avoid Rowridge but get Salisbury.

Kevin: No transmitters are being taken down that have already switched over.

There are a few transmitters which have closed at switchover, but only if they were being replaced or the service they carried was removed. Three BBC One Wales/S4C transmitters in north-east Wales (Flint, Bagillt and Holywell were replaced by much better services from the Storeton transmitter (which is in England, on the Wirral peninsula). Three ITV1-only relays in north Hampshire were switched off completely as they were there to provide the Meridian Southampton service to viewers who would otherwise get best reception from Hannington, which used to provide the Meridian West, later ITV Thames Valley, service. That service closed and merged into Meridian Southampton in 2009.

There have also been a couple of closures in Dundee (Camperdown) and on the Wirral (Bidston), due to the buildings that the relays were erected on being demolished. In both cases, new relays (Dundee Menzieshill, Sunningdale) have been erected on nearby buildings.

I don't know whether the broadcasters will re-evaluate the coverage of all the relays at any point, and decide to shut some down. Treharris was predicted to cover 4,700 homes which couldn't get even one of the commercial multiplexes from Wenvoe or Pontypool; it also feeds the Abercynon transmitter which covers 2,300 households. The cut-off for erecting a relay used to be 500 households.
