    I was just wondering does any body know if the new 4000T have the same problem with COM7 ?.

    The problems reported in this thread look likely to be due to various factors, possibly including location, weather fluctuations, environmental conditions (RF interference, aerial problems, setup, etc), and (as a contributory factor in the case of YouView boxes), lack of manual tunung capability. (The 4000T does have manual tuning capability, I understand.)

    Some of these factors, such as the weather, location of nearest and any possible competing transmitters) are not within the user's control. Others, such as setup, aerial, local RF interference, can be corrected.

    First step - to find out which transmitter your Freeview tuner is most likely to receive from, try putting your full postcode in the search box at https://ukfree.tv/prediction. Gives a very good report on nearby transmitters.

    I agree but I have also have another make of HD recorder as well and HD TV and they have had no problems with COM7 channels, just my Humax 2000T. I don't think we will ever get to the bottom of this issue unless Humax and Hannington can get it sorted, but some how I think this problem is here to stay.

    I hazard a guess that the basic problem is COM7’s weak signal, and the reason Hannington figures in a number of reports is down to geography and the presence of multiple relays and competing transmitters.

    Eventually, difficulties in receiving COM7 are likely to be resolved by spectrum reallocation. No more COM7, no more tuning problems.

    You are making the assumption that COM7 is a weak signal, yet my TV says it is actually stronger than COM8, which I have no problems with at all. When present, my youview box says COM7 is 75%. I remain unconvinced it is solely related to signal strength.

    It's not an assumption. See https://ukfree.tv/transmitters/tv/Hannington

    Reception for any given installation can be affected by various other factors, as mentioned above.

    I'm well aware that recently they have added the "possible weak signal" line. The word possible does not mean definite, and this problem has been ongoing for around 6 months now, long before that status was updated. It's just "possible" they don't know what the problem is either.

    According to the link Com 7 has more power than Com 5 and Com 6 (though of course the fact that it's DVB-T2 may be relevant).

    Current status is not the point. The page linked to shows the wattage for the various MUXes.

    It's just "possible" they don't know what the problem is either.

    Current problems are usually reported on the DigitalUK site. (http://www.digitaluk.co.uk/help_and_advice/engineering_works). Looks like the "possible low signal" is due to planned engineering works.

    It's extremely unlikely that there is any problem with the Hannington transmitter which DigitalUK is aware of but failing to acknowledge.

    Less than the PSB MUXes though. How does DVB-T2 affect it, could you explain?

    Because the set up chosen for DVB-T2 implementation in the UK favours capacity over signal robustness (Down to the chosen fec I believe).
