TERRY: As no faults are listed against the Caradon Hill transmitter, nor are any engineering works taking place at same, I feel that your problem is more inclined to be down to the fact of receiving signals from lower powered transmitters via a line of sight obstruction. The newer HD channels referred to, namely COM7 & COM,8 only radiating on 10.5Kw and 2.5Kw respectively compared to PSB3 (HD) on 100Kw.
By the way, the line of sight obstruction referred to can be seen by opening the undermentioned link.

DJC / Elizabeth Murray : True Movies (82) has now been removed from Freeview listings with the exception of the Manchester area covered by Winter Hills (low powered) G-Man multiplex transmitting on C57.

andy: Your location relative to that of the coverage area of Winter Hills L-Liv Multiplex transmitter indicates Chester as being well outside of same, DUK's reception predictor somewhat backing this up by listing reception of this transmitter under the heading of "poor".
As no faults are listed against this station nor is there any engineering work taking place at same, I feel that your problem is simply down to the erratic signal levels frequently experienced with out-of-area reception during changing weather / atmospheric conditions, the signal from the L-Liv Mux having dropped under the level required for reception.
If your TV has a "manual tuning" facility? enter C56/754.00Mhz into the box then pause at this point, do "not" press search etc, as if any signal is being received the level of will be seen on the indicator bars no matter how low it might be. This procedure working on most (although not all) devices.

GMAN73: Many thanks for your update on the situation, pleased to know that the compact log / booster installation turned out a success, something which I am sure would "not" have been the case with the dome aerial, as these devices basically comprise of a loop of wire coupled into a high gain amplifier.
I will say though, that if there hadn't have been any possible issues connected with outdoor installations in your locality I would have suggested fitting the slightly larger (2'6"/76cm) DM18 log, this type giving a "slightly" higher output, however, this type would obviously have attracted more attention over that of the compact log, something its best to avoid!.
Cheers / jb.

Robert Lee: Yes, but it has to be appreciated that your location is closer to the extended main lobe of the signal beamed out from Winter Hill, plus the signal path approaching your area does not run close to the ground, this being why DUK's reception predictor indicates your area as having excellent reception from all Muxes.
Andy on the other hand is well short of one of the side lobes of the signal, and which runs close to the ground from around 2 miles out from his location, this making the signal more prone to being affected by the surface of the terrain and what is growing on it, like for instance trees, the likely reason for most aerials seen in the area being mounted on top of high poles.

Andrew Harrington: Engineering work is presently taking place at the Sutton Coldfield transmitting station, likewise the problem referred to could well be related to events at said station, a notice warning of "possible weak signal" having been posted on the engineering page.

Nigel: Regarding your latter statement, the answer is yes!, as what you have reported is inclined to indicate that the internal hard drive is on the way out, not exactly unusual with that brand of PVR.

seb: Unfortunately you have moved into an area notorious for bad reception, both main stations that are receivable, namely Sandy (Anglia) and Sutton Coldfield (Central) predicting reception as only being good(?) on the main PSB (BBC / ITV) channels, reception of all COM channels indicated as "poor" from Sandy and "variable" from Sutton Coldfield.
To be perfectly honest about it there is nothing you can do, as the reception problem is caused by the signal path from Sandy experiencing a complete line-of-sight obstruction from approximately 11 miles prior to your location.
I would advise thinking along the lines of Freesat, as its about the only option you have to enable you to enjoy trouble free reception.
By the way, the line-of-sight obstructions referred to can be seen by opening the undermentioned link.

David Porter: If you are referring to using a Freesat box in its non-Freesat mode, try tuning the programme in using following settings, the FEC having recently been changed from 2/3 to 5/6.
11.385Mhz - Pol: H - SR: 27.500 - FEC: 5/6

Shirley: Your TV has likely picked up channels from another transmitter rather than from the station normally used, however, this possible reason cannot be checked unless a post code is supplied, one from somewhere nearby (e.g: a post office) being suffice.
You should though try carrying out a second retune, as this "might" correct the problem.
