I have had no signal for my TV all afternoon and evening ?
Please can you tell me what is going on ?
I live near shepton mallet, Somerset and so I presume my transmitter is the Mendip Transmitter

I'm on the Mendip transmitter and there has not been any problem at all. Perhaps it is worth checking your aerial system and all the connections?

Since late afternoon we have only had semi-reliable service on the Muxs on Channels 48 & 49, and dropping in and out (more out than in) on channels 52 & 56. Nothing at all on channel 54, so no HTV/Channel 4/Channel/E4. Is that likely to be the result of the planned "MENDIP transmitter - MainPossible weak signal" advertised on Digitul UK and mentioned above? Or just the weather?

R Bennett: Because ITV Be is carried on COM4 multiplex, the Commercial (COM) multiplexes not being available from Crewkerne transmitter.
The thing to do is to see if you might be in with a shot at receiving from Mendip to give you all channels. A postcode would allow some idea of likelihood of success to be gauged.

I 'm sure I heard a little bird say that it was thought that BBC West was going HD, YES HD in 2015. Does anybody know if there's a grain of truth in this?

Hello team
I am having fun and games with 3 of 4 TV's since we moved to Portishead. An older Panasonic plasma (about 6 years without HD) always tunes to ITV Wales when I use auto tune but so long as I manually retune is fine but I don't understand why. Postcode is set to home.
In a variation my brand new Samsung and 3 year old Humax HD box works fine for normal TV broadcast but for ITV HD it selects the Central adverts and local news whether I tune manually or auto - I am selecting transmitter 2 on channel 58 which is what this site and the other sites have agreed with. A really basic TVonic box on an old analogue TV does not pick up basic Wales BTW and all are on a common aerial via an 8 way distribution box in the loft.
Any thoughts?
thanks, Andy

Andy: You havn't given a postcode (please everyone, if you want help, then a postcode is extremely important!), but at a guess its the way the algorithm driving the TV's search software - each one is slightly different.
Have a look at your localish transmitters on Digital UK, the frequencies are different, but so is the response of the software. Really cheap set-top boxes like my Goodmans vaguely look in the right direction, and pick the first transmitter, even if its wrong. Better brands (like my Sony PVR) pick the proper transmitter perfectly. And of course you might be getting a strong signal from the transmitter facing away from the direction of the aerial as well.
I'm sure others can go further with the various quirks, etc of picking up the signal, but basically, if you want the all the same, you'll have to manually tune them.

Andy: It's probably got more to do with the different ways in which the devices "decide" which signals to go with. Some go with the first they find, others work out which is the strongest and others ask you which network/region you want (this actually being a question as to which transmitter where they are from differing regions).
We don't know your exact location but Portishead slopes downwards, towards the water, meaning that Mendip is likely to be out of line-of-sight, but Wenvoe, across the Severn, may be stronger.

Andy: All Welsh transmitters broadcast Central (West Midlands) ITV HD, so you're probably receiving that service from Wenvoe as suggested by Dave.
