Adam B: What you have been told as far as prices are concerned is perfectly correct, as although the average price for a Ch59 4G filter is around £10.00 or so, however when Ch60 comes into the equation the financial situation somewhat changes as the very lowest price of one of those devices, namely the Filtronic / LTE : PSD008-V5-P is £32.67.
Although bang up to date information is not generally available as far as phone companies intentions are concerned, but should a 4G installation be commissioned in an area where one TX stations muxes operates on Ch60 it would be interesting to find out what grade of filter is being sent out to viewers.
The top link shows the various types of filters, and the bottom link the outrageous prices of some types.

Adam B: If the second link fails to open try this one, once opened selecting LTE and scrolling down the list.

MikeB: Well yes! but as far as I am concerned at800 are the people who are most likely to be kept up to date "before anyone else" with regards to the situation, although I suppose that if Fiona contacted at800 and enquired as to why she had been sent a filter they just might have explained the reason, or of course on the other hand possibly having informed her that she had been sent the device in error!
But though, when taking into consideration the fact that Fiona's location is in Liverpool then I would think it to be almost guaranteed that a 4g installation (or multiples of) is very likely to be in the pipeline, something which at800 is possibly aware of hence the reason for them sending her the filter.

nick: When you mention "your small portables" are you referring to digital TV's or analogue ones being used as monitors? the only reason for asking being that on having looked though all of the postings made on MikeB's digital spy forums link one well known reason for this problem being experienced on analogue sets is conspicuous by its absence of being mentioned, namely video overdrive resulting audio buzz and which the intensity / frequency of is heard as being in sympathy with the white level of the picture.
You can up to a point get the same effect on poorly designed digital TV's and due to the following reasons, (1) a combination of PCB tracks of a sensitive nature running too close to each other, or (2) PCB earth loop problems, (3) poorly designed power supplies and which (2) also comes into the equation.
In all of those cases, using excessively high contrast levels on the picture generally results in making the problem worse.

Trevor: As far as manual tuning is concerned the channel number is suffice, as although two of CP's muxes (HD & COM6) are transmitting with a negative offset of 200Khz under the set frequency for the channel, this on a modern set is neither here nor there and as such can be disregarded.
On the subject of using a short length of wire, any wire such as twin flex used on some table lamps or even bell wire, the point of the test being to get an idea of strength of the signal in your area as although you should in theory be receiving a strong signal from CP, however in reality you might not be as witnessed by the large number (approx 7) of low powered PSB fill in transmitters located within a few miles of your area.
Just a little point I was wondering about, I noticed in your original posting that you had mentioned "we" when referring to the problem, is this an indication that your neighbours who are also on the same communal aerial system as yourself are also experiencing similar difficulties? however no matter what you should select a programme channel on the TV whose reception is a bit iffy, then without touching anything else remove the aerial and connect a short length of wire into the middle receptacle on the aerial socket and see the picture returns.
Please note though, that should you be located on a ground floor then this test might not work.
When referring back to the strength / quality indications previous made, are they being given against a possible maximum indication of 100% on the scale that you are observing them on?

dvae: Your box isnt by any chance a Huawie brand? as this is well known fault with these boxes and which Talk Talk (if you obtained it from them) is well aware of.
Should that said be applicable then I would contact them.

Stuart Ahrens: Try removing the aerial followed by carrying out an auto-tune which should blank out everything stored in the tuners memory, once completed reconnect the aerial and carry out a second auto-tune as this in most cases will resolve the problem.
If though for any reason it hasnt, then you have no option but to carry out a "first time installation", this also known as "factory reset" / "default setting" or some similar sounding name dependant on brand.

A Walsh: Drama on Freeview is on the same transmitter as ITV3, if you can receive ITV3 OK then try removing your aerial connection followed by carrying out an auto-tune to blank out everything stored, once completed reconnect the aerial and carry out a second auto-tune which hopefully should have rectified the problem.

andy: No matter how many times you have retuned your TV this message is an indication that its not up to date.
Some TV's or boxes require whats known as a "first time installation" to be carried out, this also known as "factory reset" / "default setting" or some similar sounding name dependant on brand, this in most instances curing the problem.

kenneth coxon: This type of problem can be caused by more than one reason, but if your TV's are connected into the same aerial system then the problem could be caused by the signal level in the line feeding the Toshiba being lower than that being fed to the other TV, the obvious way to check being either to test the Toshiba out on the other TV's aerial connection, or alternatively the other TV on the Toshiba's connection.
However, should the Toshiba TV prove as being perfectly OK when used on the other line then you should check the aerial socket that the Toshiba is plugged into as well the arrangement used to split the aerial between both devices.
Maybe you could indicate what type of splitter you are using, passive or powered? also when you say that the signals are breaking up, what programme channels are involved?
Further advice dependant on feedback.
