Mrs Tracy Richardson: A post code or one from nearby (e.g: a shop/post office) is always required with queries of this nature as its impossible to check on the transmitters that cover your area without this info.

Duncan: Well Siemens equipment has always been regarded by engineers as being top brand, and on a browse through the spec of your C595 it certainly appears as offering virtually every facility that one could desire in a DECT phone.

But with regards to moving the base station, although your intention of moving the phone into another room is virtually guaranteed to eliminate any possibility of a re-occurrence of the problem, that is provided its not just on the other side of the wall, in practice you would generally find that the offending device need only be moved about 8 feet or so away from the receiver (including its aerial feed cable) to have the same effect.

By the way, although you will most likely have understood this anyway, but when I had mentioned "non frequency specific digital noise" I was not referring to the RF transmission side of the phone, but the noise that's radiated from any digital processing circuitry but which is mainly encased in plastic therefore offering zero screening, although your particular device will likely have an element of metallic screening around the processor area.

Catherine: Sorry about the delay in replying, as although I did see your reply on May 10th in answer to my query regarding the model number of the TV in question, but though I did not answer straight away simply because that your answer raised a problem that's frequently experienced when dealing with devices especially made for chain stores (Curry's in your case) the problem referred to being a total lack of info on the model in question, as user manuals for same cannot be downloaded albeit that amazingly I do have the technical service info for the set, however this does not give info on anything connected to the menu system used by the TV.

That said, if your communal aerial is mounted horizontally then it will likely be facing Mendip @ 15 miles / 185 degrees , therefore the programmes that you have reported as having difficulty in receiving are spread across the three commercial transmitters, the mux channels (not EPG) used by them being : 48 - 56 -52.

As the menu system used in your TV is unknown, first of all scrub the channels already stored by carrying out the procedure of removing the aerial followed by carrying out a complete auto tune, then once having verified that nothing is stored by witnessing a "no signal" warning when you press the programme guide, what to do next is go into the "set up" menu / tuning and look for "manual" being indicated, this usually always located next to "auto tune", if you see it click on it and that should come up with a box that you enter the mux channel number into, should you manage to get to that point enter 48 followed by pressing search or scan and storing anything found, then temporarily exit the menu and press on the programme guide to check the list of commercial programme channels found during the scan and with ITV3 (10) being first on the list, giving an update on results when further info can then be given.

I should say though, that on checking back all you have said since your original posting is inclined to suggest that your problem could simply be caused by a combination of the signal strength being received from the commercial services being on the weak side, but with this being coupled to the tuner used in your particular TV being of the less sensitive variety.

The reason for saying this being your report that one of your neighbours has perfect reception on the channels that you are having problems with, and so another thing you could do is to try using another jumper lead between your TV and the wall plate or box, this action preferably taken before carrying out the aforementioned procedure.

H.J. Clarke: Have you as yet tried the a signal strength / quality check using the manual tuning method? that is after you entered the mux channel or frequency into the manual tuning box this action NOT being followed by pressing search or scan, because by not doing the signal strength of the channel / frequency entered is usually indicated.

In other words this procedure results in the tuner acting like a form of signal strength meter devoid of the threshold levels that come into play once that search is pressed, this being the reason why some people find that although having previously witnessed signal levels being indicated relating to the mux channel having been entered that the scan did not result in any channels having been found, this simply because they were under the level required by the tuner to resolve a picture.

Floyd: The reason I basically mentioned commercial channels was that in your original posting it was only the commercials that you had referred to, albeit that you did of course include the BBC in one of your later postings.

However as far as the situation changing between day and night is concerned, this is something that's very commonly experienced by many who are receiving their signal via an element diffraction, that is bending around obstructions such as hill tops etc, and the type of situation thats very applicable where your signal is concerned, the changes in signal levels received being caused by the normally occurring atmospheric changes that take place between night and day that alter the reflective properties of the atmosphere.

Of course the simple way around this is to use a variable booster in line that can be adjusted as required to suit the occasion, as in many cases when the signal vanishes its just dropped slightly under the level required to resolve a picture and with a slight boost lifting it back up again.

But though this solution will only be successful provided that the variation in levels seen does not include the signal quality vanishing, as nothing compensates for a complete quality loss.

This being an example of the type of booster thats very successful in the type of situation referred to.

Lady Patrice Naughton: Although the Oxford transmitter is listed as being liable to interruption as from the 27th only one of the six mux channels used by Oxford (ITV3 etc) changed frequency today from Ch62 down to Ch50, and so this requires either a fresh auto-tune being carried out or alternatively Mux Ch50 being manually tuned in to regain the programmes on that mux.

However, if no signal whatsoever is being received then that can suggest a possible fault on your aerial system, as the "liable to interruption" notices generally never refer to any period of time longer than say 15 minutes or so, and nothing has been posted on the engineering notice board as far as faults are concerned.

James Paterson: I carried out a check on Walthams BBC mux Ch49 a few minutes ago and its perfectly OK in the Stamford area, and so although a complete retune should not really have been necessary as a manual tune on Ch49 should have been suffice try a complete auto-tune, of course making sure that you select east Midlands as the area if this request springs up after having carried out the auto tune.

Wendy Leak: Yesterdays retune was purely because the BBC changed from Ch61 down to Ch49 and so you should carry out a manual tune on Ch49 and the BBC will return to the EPG list.

Pat: You should try carrying out another retune as there were one or two reports of a glitch (short drop out) having occurred in the signal after the frequency change and this may have coincided with your retune.

If you have any problems then you might have to carry out a "factory reset" on your TV followed by using its "manual tuning" facility to tune in Waltham, that is "only" if you find that you are picking up a mixture of Waltham and Sutton Coldfield's mux channels as its possible to receive signals from both sources where you reside.

Graham Cole: If as I understand it, you are wishing to use add a Freesat box to your system then as MikeB has said you will require to run a coax from same to your dish, this being qualified by adding that provided the LNB on the dish has a spare output port, this being something which can be verified by looking up at where the existing cable enters the LNB and observing is any threaded spigots are seen.

As far as feeding the Freesat boxes output into your system is concerned, you cannot do that in the same way as done with a Sky box as Freesat boxes do not have RF modulators, and so a separate modulator would have to be used such as the types seen on the link, and with the RF output of the modulator being fed into Sky boxes aerial in socket and the aerial connection presently on same being connected into the RF modulators aerial input socket.
