DemThonp : Indications are that your location is line-of-sight with the Winter Hill transmitter @ 27miles / 126°.
However, you should carry out a signal check on the HD channel you are viewing to make sure that you haven't picked up Lancaster's HD service rather than Winter Hill, Lancaster's HD being on Mux C21 whereas Winter Hill's HD is on Mux C57, and with its new COM7 HD service being on C31.

DemThonp: No!. The channel numbers you have given correspond to that being used by two different stations, namely Lancaster and Moel-Y-Parc, neither of indicated as providing the best signal in your area. Nearly all of the aerials seen in the Falkirk Avenue area are pointing towards Winter Hill, therefore you should delete everything stored in your TV tuners memory by removing the aerial followed by carrying out an auto-tune, reconnecting the aerial on completion to ensure that "no signal" is indicated if you try to select a channel Should this be the case, then the next stage is to go into your TV's tuning menu / "manual" tune / and enter the following channel numbers "one at a time" followed by scanning each of them in turn and storing the results. Winter Hills channels being / C50 (BBC) - C59 (ITV) - C54 (HD) - C58 (ITV3 etc) - C49 (Pick TV etc) - C55 (4Music etc) - C31 (this being the new COM7 HD service)

hector: 60% is at the lower end of what is considered acceptable as far as the reception level of "quality" is concerned, however when you say that all channels are 60% apart from the HD channels are you meaning that nothing is being received on HD?, because should this be the case then are you sure that your TV is not just a Freeview HD ready model? as these types can only display and HD image from some externally connected source as their tuners are not capable of receiving it, HD reception requiring a TV or box to be fitted with a DVB-T2 tuner and "not" simply DVB-T as used for normal SD reception.
If you have the instruction manual for your TV have a look in the specifications section / tuner and check what's mentioned under that heading.
Should you experience any problem in finding this info, if you come back with the model number of the TV in question this can be checked out for you.

Mark W: If you are located line-of-sight at a distance of say under 10 miles or so from the transmitter then you should be aware of the fact than a signal that's slightly over the top in strength can block HD reception, this sometimes being in an intermittent fashion dependant on weather conditions etc.
Another point to note being, that the signal strength / quality indications (especially latter) cannot be relied on as being in any way accurate when a device is operating under signal overload conditions, as the excessive signal level upsets the measuring circuitry usually resulting in a low, or zero reading.
However, a more accurate assessment is not really possible without a post code (or one from nearby) being known, as this would then enable details of the signal strength expected at your location to be accessed .

hector : Well, although 60% quality cannot really be said as being ideal, it can however be perfectly OK on many devices provided that its observed to be completely stable if monitored over a minute or so, 80% + quality being a far more desirable level and with the signal strength usually lagging slightly under this.
If you have positively verified that your TV is indeed fitted with a DVB-T2 tuner? then its unusual "not" to be receiving anything at all on HD, therefore in order to get a better idea as to the cause of the problem maybe you could provide your location, this preferably being in the form of a post code or one from somewhere nearby, e.g: a shop / Post Office, plus also a run down on the aerial system you are using.

hector: The HD transmitter you are referring to is already one of the second most powerful in the country, and so your problem is really being caused by the aerial system you are using and not in any way connected with the transmitter.
However, unfortunately its not really possible to be able to offer advice as far as remedial actions are concerned without having knowledge of your location, PLUS of course knowing where your present aerial is located? although "if" by any chance its a "same room as the TV" type then there isn't much that you can really do about it except to try moving it around whilst you are observing the quality being indicated on the screen.

STEPHEN PARTNER: Engineering work is presently being carried out at the Ivybridge transmitter and so unfortunately breaks in reception can occur at any time, the main point to remember being "not" to try a retune or alter anything with your installation if its found that the signal has vanished as it will return of its own accord.

sam: This could suggest that the signal you are receiving from the high powered Clermont Carn transmitter is overloading the input of your receiver.
Try a test by checking the result of using a short length of wire (about 5 feet or so) connected into your boxes aerial socket rather than the loft aerial, the test only being applicable as far as the reception of RTE programmes are concerned.

Steve: Could well be! as older Sky boxes such as the DRX280 were notorious for power supply problems caused by leaky / dried out electrolytic capacitors. Try the undermentioned procedure, if all appears then the problem is most likely to be down to a defective power supply. LNB checking procedure: 1: Press Services and select 4" (opens with picture settings highlighted) 2:- Press: "0 - 1 - select" (opens with LNB set up highlighted) press on this. 3:- A list of the various settings will appear, and although they may match up with what's indicated below still press on the red "reset all settings" button (at bottom left hand side under the menu list) 4:- Use the up/down arrows to highlight "Save New Settings" then press select. The correct settings for the LNB are / Low frequency - 9.75 High Frequency - 10.60 The LNB power supply should always be set to on. The 22KHz Command should always be set to on.
