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.

Looks like all the Tacolneston channels are going to have different numbers around Apr - Jun 2018, maybe it will help our situation!

sounds a bit like the only change might be a new source of interference such as from a telephone mast . Or also possible that you are getting a signal from a Dutch transmitter . There are some on UHF channel 31 . But Dutch interference usually only shows up occasionally in times of high pressure weather. Loss of signal shows as a low reading of signal strength . Interference can read like high signal strength fooling you into thinking everything is ok. Also living near the coast I have reverted to Freesat to avoid continental interference . I may switch back to freeview next june when the freeview channels will be changed but there is not much incentive as you can now watch all the same channels on freesat.

Yup, time to switch to Freesat: Freeview is very likely to become unwatchable.
Bill, your BBC4HD on COM7 doesn't surprise me at all. This channel/mux drops s/s frequently. BBC et al refuse to admit it but you can watch s/s and quality shift, many people have exactly the same problem and excuses such as propagation issues don't wash.
That said, I would have thought that with the figs you give recording would be ok. Points to a transmission fault of some kind.

Mardler : North Norfolk has always been problematic for TV reception from Talcneston - the geography of the area means a lot of places are blocked, hence the reason why many aerials use Belmont instead.
Thats the nature of the physics - when people start saying that their reception has got a lot worse, then that points to problems within the home system - the transmitter is in the same place, with the same power output, etc. There are always people who insist it has to be the transmitter, the BBC, etc, but it very seldom is. And some will tie themselves in knots trying to explain signal loss away, often ending up confusing themselves.
If people find it easier to go to Freesat, etc, fine. There is no point in repeatedly trying to do what cannot be done - physics hasn't changed. But if the change is relatively sudden, then almost certainly its not the transmitter or even Freeview itself.

Looks like many others are having the same problem, and it does seem to be pointing to a BBC issue

Once again no TV reception at all (Bad or no signal) for three nights last week as located in a reception "dip". Had to watch TV on computer.

HIlary Woodward: Did you read or act on any of the replies to your previous post a year ago? No one else is reporting any problems with the transmitter so you need to look for a fault in your aerial system. Complaining about it online won't do anything to fix the problem if you don't act on the advice given.

A new breakthrough today. Done a re-tune for all channels, and BBCFourHD (106), has now come through on Channel 37 Com 8, and is recording fine. (All the rest of the channels that have come through on the original Com 7, still won't record, but nothing of interest on those anyway).

here is an interesting website where you can check the quality and reliability of tv signal that you are likely to receive at any given post code . You can see from Tacolneston that there is a retune required in February 2018 and one in april. The changes are due to frequencies above 700mhz being given over to mobile phone use. Digital UK | Clearance events in 2018
The channels marked orange are not guaranteed to always give 100% perfect reception . But as Mike remarked it has always been difficult to provide perfect reception in ALL parts of Norfolk ALL the time for genuine technical reasons .
I also note that in most areas a wideband aerial is the best future proof choice but in difficult areas after april I think I would recommend a group B aerial

Hardy:
That is a useful website that some of us contributors already use. If people put their post code into this website one of the blue boxes underneath their posting is a link to the digitaluk website with the information relevant to the given post code. Used together with the reception prediction and the terrain information, it is very useful for us to offer suitable advice specific to a given location.
The use of a Group B aerial only applies to some areas as others use higher or lower frequencies and will continue to do so for some years. It is better to use a Log-Periodic aerial that is able to cover all the forseen frequencies, they are sufficiently directional to eliminate most extraneous signals and sufficient gain (if you choose the correct one for the reception area) so most will not need an amplifier, though some will if they are some distance from their chosen transmitter.
