Mr Scott: A simple google search for "uhf (channel) frequencies" would give you this list UHF channel and frequency guide - Tech Information - Digital Spy
Use the centre MHz frequency and ignore those above 60 as they are not used for TV anymore.

Every time I watch the BT sports (Rugby) I get picture breakup and then a message that I am not receiving a signal. I can get all other channeld except for the BT ones.

Jim Robertson: That is odd because you would expect to have the same issue with other services carried on COM6 multiplex (which is what BT Sport services are on). Other COM6 services include 4Music, Yesterday, VIVA, Ideal World, ITV4, QVC Beauty, Film4+1, 4seven, RT. Do you have the same issue with these?

Mr Scott
Remember that the programme numbers used on a TV set are only used to assist viewers to select a particular service. The are often referred to as 'Logical Programme Numbers' for the very reason of avoiding confusion between the actual transmitting frequency (the UHF channel number) used to deliver a particular multiplex of programmes and the number you select on the TV. (A multiplex will contain the information for several programmes at the same time, see the listing for the different transmitters to what services are carried by each multiplex.) There are channels from 21 to 60 used for terrestrial TV broadcasting in the UK and the large number of transmitters are allocated a set on channels to use. The original intention had been to keep the channels used within a particular aerial group so that only one was needed. Nowadays, that is in the process of changing so that Ofcom could make more of the UHF spectrum available for other uses, such as mobile phones. There are discussions on-going about how that should be implemented, if at all, and hence what channels should be used by which transmitter, but there will not be much information available until the plan is agreed, if it is, and it is then likely that a further re-allocation of channels will be needed.
Note that Freeview main transmitter will use at least 6 channels, but that some are gaining further services requiring the addition of one or two extra channels. Many of the smaller transmitters only provide a Freeview 'Light' service containing just the PSB services like BBC and ITV, but often none of the purely commercial services, such as QVC, etc.

I too had this problem several weeks ago, and complained bitterly! However, I did then notice that my telephone wifi base station is close to the box on which I get BT Sport, and when the phone rang it pixillated - I've moved the base station a few inches - problem solved!!

We have just recently purchased a new LG 32LG3000 tv with built-in freeview. I have done numerous auto re-tunes and tried turning it off and on again and done a factory reset but still nothing works. We don't get channels 3, 4, 5 and 6 and some other random ones through out. We previously had a sharpe tv with built in freeview and that worked perfectly fine so I don't understand the issue, please help.

can you please show a diagram of the back of the hd box as we have had it unpluged to move it and are not sure where the wires thank you

e byrom: Voila
the mains power connection (1), carefully unscrew the satellite dish links (2) and (3), and then take out the HDMI lead (4) to your HDTV. If you have an "surround sound" amplifier, you may also have a digital audio connection (5).

Apropos Mike P's response to Mr Scott which touched on channels not all being in the same aerial group. If/when this is so, avoid at all costs the so called hi-gain aerials which achieve their high gain characteristic by narrowing the frequency coverage as well as the directionality. When/where you have a situation similar to mine with some Mux channels below 30 and the remainder around 50 (ie, a wide gap between the groups) then you'd be better with a wideband aerial (probably a log periodic array). This should have a substantially flat frequency response across all of those channels, albeit with an aerial gain of only about 11dB. This can then be compensated (if necessary) by an additional downstream amplifier, possibly as part of your aerial distribution system.
