I'm living in Lylehill Road East (BT39 0HQ) about 300m from where the Roughfort Pub used to be. After the DSO & re-tuning several times I've lost BBC1, BBC2, Film4. My aerial is positioned in the loft. Can you explain this ?

Brendan : Some older receivers won't work with the post-switchover signals which could explain why BBC One and BBC Two aren't being received. Knowledge of the make and model number will allow advice to be provided as to whether this is the case or not.

You have posted on the page for the Carnmoney Hill transmitter which does not broadcast Freeview before switchover. At present it only broadcasts BBC standard definition services and after 24th October will carry Public Service channels only (so no Film4, Dave etc).

Does your aerial point to Divis which is at 168 degrees? (Aerial will be horizontal)

Carnmoney Hill is at 100 degrees with the aerial vertical.

Brendan: According to Digital UK's postcode checker, you should be getting excellent reception from both Divis and Carnmoney Hill post DSO, as well as the NI mux from Black Mountain and Carnmoney Hill.

Dave could be right, though this shouldn't affect Film Four at this stage.

The BBC 1 and BBC 2 problem could be caused by signal overload, so you may need to get someone out to either remove/bypass an amplifier, or fit an attenuator.

Gail: I've no idea as I don't know what the set up proceedures are on your T.V.

However, after the 24th there should be no need to switch to analogue T.V. as all analogue signals will be switched off on that date.

I presume you are receiving Carnmoney Hill as this is the first time you've actually had Freeview stations ?

Wait until next Wednesday when you'll no longer need analogue T.V.

Gail: If you are sure that you saved the chanels picked up during a Freeview auto-tune as not all TV's / boxes will automatically save them, then you should completely reset your TV by carrying out a "factory reset", sometimes known as "default setting" then follow this with a normal auto-tune.

If this does not cure the problem then please indicate the model of TV or box in question, although I would wait until after October 24th when switchover is complete before making any alterations, as you would have to carry out a rescan then anyway.

Will we be receiving any COM4/5/6 ( i think) channels such as 4Music, Viva, etc? and Is there anyway of picking up signal from the Divis Transmitter?
