Which companies have run the Channel 3 services in the Mendip transmitter area
We use Mendip as our main Freeview source and there are no problems with the transmissions. So I concur with StevensOnln1 that you should carefully check all the aerial connections right from the aerial to the back of your TV set.

There have been recent problems in my area (North Cadbury, Somerset BA22) with drop outs in HD. This may be related to the new channel changes. A total retune seems to have cured the problem.
However WARNING: I receive regions West (Mendip), South West and Wales. Most TVs will ask which region you want in cases like this. I found that many channels were missing after retune, and these needed manual retuning.

Indeed a retune should resolve any reception difficulties in this instance. That you have several transmitter options available means that you have to be careful to ensure it tunes to the Mendip transmitter if you want HTV West, BBC 1 West, etc.
Whilst you are checking the channels the TV has tuned to, check that the signal strengths aree between 60% and 85%. Either less or more will give you picture breakup and sound problems.

Graham: As you've posted on the Mendip page, presumably you are talking about receiving ITV Central HD on Freeview. This is because ITV currently only transmit four of their regions in HD on Freeview in England (London, Meridian, Central and Granada). More ITV HD regions are available on satellite, but as ITV HD is broadcast on Freeview capacity belonging to the BBC, we probably won't see any further ITV HD regions being made available via Freeview until the BBC are in a position to start broadcasting regional versions of BBC One HD (both are broadcast on the PSB3 multiplex which is owned/operated by the BBC).

No COM7 or COM8 (UHF chs 33 and 35) at the moment (~3am), are they off at night time for engineering work? COM7 was fine earlier today. I see that they will disappear at the end of March this year, perhaps that is related. Other muxes e.g. the man HD mux (ch58) are fine.

TimH: It would be very unusual for any engineering work to take place overnight (unless there was a fault). COM7 & COM8 are not closing in March, they are moving to form a national single frequency network (SFN) on UHF channels 55 & 56 (where they will remain until some time between 2020 and 2022), although according to Digital UK those changes aren't happening at Mendip until Spring 2019. Several multiplexes will change frequencies around the same time (although it looks like this will happen in three steps on different dates). The only changes taking place at Mendip this year are that COM5 will move to UHF 33 and COM7 will temporarily move to UHF 36 on 27th February.

we have a Philips HD pvr HDT 8520 working off Mendip: all channels OK and decodable, including CH33. It lost the mux which includes BBC4 HD, so I ended up doing a factory reset and retuning. It pauses to ask which network to choose: "West" (116 tv's) or "Com78 National" (28). You can't choose both. If I select "West", it then puts the BBC4 HD mux channels up in the 815 channel area with no metadata to enable program recording. If I choose "Com78 National" we have the correct channel numbering for BBC4 HD (106) and the other HD channels in Ch33 mux, but not for the normal BBC1/ITV/Ch4 hd's etc, which end up with no metadata, numbered in the 200's I think. Can something be done to make the networks converge? There must hae been a change incompatible with with the box's firmware?
