The symbol shows the location of the Tacolneston (Norfolk, England) transmitter which serves 330,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Tacolneston (Norfolk, England) mast?

Hardy: I do understand that these are on lower power but my TV tuner using the loop through from the box manages to show the Com7 and Com 8 channels without any problems.
I recall that when the power levels were much lower a few years back I'd get some pixellation on some of the channels from this transmitter.
Today when I get a constant clean picture on the TV and none at all from the box is confusing. It's been suggested that the amplifier I am using could be the issue, but surely it would be a problem for the TV tuner and the Youview tuner.
Aren't the power levels on Com7 and Com8 far higher than the power levels we had prior to switch off of the analogue channels? The steady picture I get through the TV suggests that they are and that the tuner in these Youview boxes are the main issue.

I'm not sure about the power of COM7/ 8 after analogue switch off . I know its now 18 killowatts . wheras the main channels are 100KW. The local Norwich channel comes through fine on 10Kw because it is standard definition. A stronger signal is needed for proper reception of HD. I agree that the youview boxes are less sensitive than many tvs . But it can be tricky to get the right degree and type of amplification that would fix it. The "proper" technical solution is a better aerial that is sensitive to com7/8 . The super solution is the use of two aerials one of which is filtered or sized to just pick up com7/8 . But is the expense and bother worth it.? Especially as in the future com7 and 8 are likely to be discontinued.

Hardy: COM7 & COM8 did not come into existence until several years after analogue TV was switched off. According to Digital UK, COM7 & COM8 are both broadcast at just over 18kW from Tacolneston. The local mux uses QPSK modulation which is much more resilient but comes at a cost of providing much less capacity and therefore is able to broadcast at a much lower power level than the main muxes.

yes Stevens . the point being that before the recent change they were 27.4kw and 24kw .At the new level of 18kw they are a bit harder to receive in fringe areas.

Paul White: It's highly likely that you're getting interference from other distant transmitters that you would not normally be able to receive, due to the current atmospheric conditions caused by the hot weather. Do not attempt to retune.

Paul. I assume you retuned your tv after the frequency change of june6th? You are so close to the transmitter even a small indoor aerial should work. Though indoors where the aerial is placed can be quite critical . I don't think interference from other transmitters would be strong enough to cause problems. Outdoor aerials are always preffered (in youre case a short log type should be ideal) . In the loft being a second choice to place it . With such a strong signal an attenuator (signal reduction device) may be needed inline with the cable.

Hardy and Stevens,
COM7 & 8
This is news to me. I only ever saw both being broadcast at 24Kw never18! My sources were this page and a more reliable and up to date one. Had I see 18 I would immediately have complained to my MP.
Stevens, you say the new mix is able to broadcast at a much lower power level - you mean is restricted to a much lower power level not able. It is transmitted power that matters.
It is unbelievable that a main HD channel is transmitted at such low power. No wonder people are annoyed.

If these muxes are being broadcast at 18Kw shouldn't you update your table as it still shows 27.4 and 24?
