Gill: I would guess something has happened to the splitter. If it is powered, it could have blown a fuse. Please also see Freeview reception has changed? | ukfree.tv - independent free digital TV advice

I have a digital high gain aerial with 5 top and bottom elements.
My TV is a Panasonic TH-37PX70BA with a built in freeview tuner.
I also have a PVR, Panasonic DVD DMR-EX95 again with its own freeview tuner.
On both freeview tuners I can no longer receive the following channels: 8 Channel 4 , 11 PICK TV, 19 Dave, 20 Really, 29 E4+1, 46 Challenge, 49 Food Network
I have also had intermittent problems with:
12 Yesterday, 15 Film 4, 18 4Music, 21 VIVA, 24 ITV.
All were received in the past with no problems.
I have run the tests to exclude any Local analogue interference. I have also zeroid the TV and freewiew tuners before retuning them again.
I switched to Freeview fairly early so my aerial is pointed/lined up to the Mendip transmitter.
Since the Calne transmitter is now broadcasting digital, do you think I would receive the missing channels if I re-aligned my aerial to the Calne rather than Mendip transmitter?
If not, any other ideas how I can get the missing channels again.

Phil Smith: Which transmitter is your aerial directed at?

You mention Channel 4 being on Logical Channel Number (LCN) 8 which implies that it is tuned to a transmitter in Wales as it is displaced from LCN4 by S4C.

If you are receiving from Mendip then Arq A and Arq B are on low power until 28th March. These carry the services you identify as missing, except Channel 4.

I wouldn't go with Calne unless there is no other option as it is a Public Service Broadcaster (PSB) transmitter only as it does not carry the commercial (COM) multiplexes.

If Channel 4 does not appear on LCN8, then is it present on LCN4?

We get our signal from the Bathford relay transmitter and have relatively few channels. Wondered if there is likely to be an upgrade of this in the near future so we get a wider choice of channels?

You should be able to get Mendip, according to Digital UK tradeview, and get all the channels.

Sue Gill: It's not likely that the commercial broadcasters will install transmitters at Bath.

They choose where to site their transmitters and operate so as to generate a profit.

They currently cover around 90% of the population from approxiamately 80 of the largest (by population) transmitters. For them to broadcast from the other 1000 or so relays would roughly double their costs of transmission. They were asked if they wished to increase their coverage and declined.

As Pete Green says, the best thing you can do is have an aerial installed for Mendip. Note that two of its commercial multiplexes are on very low power until 27th March, so this might affect your reception until then.
