Steve: have you checked your signal strength - it could well be that common problem of too much signal - Freeview signals: too much of a good thing is bad for you

There seems to be a lot of it around at the moment

MikeB: Hi Mike and thanks for your suggestion. I've not looked at signal strength before so I've taken the following readings from our Sony TV (gives % quality and strength) and TVOnics PVR (displays an analogue 'progress bar' for strength so a visual estimate). ITV/C4 channels remain unstable since your post.
18 Nov 6:15pm weather unsettled %Qual %Strength
TV BBC1 83 38
ITV 21 34
C4 23 34
PVR BBC1 60
ITV 60
C4 60
Didn't record BBC figures after this as it has been fine, and no further figures for any channel on the PVR as it remained about 60%. The rest are just for the TV.
19 Nov 10:40pm weather fine
ITV 46 38
C4 37 38
20 Nov 6:30pm weather unsettled
ITV/C4/More4 etc 0 26
24 Nov 5:15pm
ITV/C4 16 30

I'm not sure what to make of these figures. PVR signal strength seems to be almost double the TV whatever the channel. Signal quality seems more significant; compared with BBC1 (80/90%), ITV/C4 ranges from 0 - 34. NB I did rescan both units when this problem first started. I haven't found any other references to viewers having these problems and this has been the longest duration of reception problems that I can remember. Any further help or suggestions gratefully received!

Cheers,
Steve

Steve: It probably would be helpful to put in a postcode when you next post, so we can the signal path etc. However, its seems your right - the PVR is fine (ok, not fantastic, but if your are on the edge of reception, understandable), but not the TV. TVOnics tuners should be not much different from Humax (if I remmber the reviews), and I know Sony turners are really sensitive.

Ok - is the signal coming into the the PVR, and then being looped through the PVR and sent on to the TV? If so, it might as simple as a duff aerial lead! Try replacing the one from the PVR to the TV, and see if it makes any difference. Frankly, if you go to Poundland, you might get some Belkin ones for a quid, so buy two and see if there is any difference when you replace both.

If there is no difference, at least you can cross it off the list, for a couple of quid.

BTW - this new layout isn't really working all that well, or is it just me?

Our post code is GL10 3BJ - Eastington and we receive Freeview from Mendip.
Why does the map show that we can't get Freeview TV from Mendip please?

Bob F: Basically because coverage maps or reception predictors cannot by their very nature be 100% accurate, nor indeed can any prediction involving terrestrial RF signals as so many variables apply, and with in your particular case indications being that you are on the doorstep of a so called dead spot for reception, the terrain indicator revealing a rather large line-of-sight blockage to the signal path between Mendip and you whereby any signal received is via diffraction (signal bending), this generally resulting in reception being vulnerable to changes in atmospheric conditions at certain times of the year, or even weather related conditions that affect the surface of the terrain, a frequent reason for random picture glitching cropping up now and again for no apparent reason.

Or to put it another way, the only prediction that can ever be 100% accurate is in cases where cable is used to supply the signal to a household.

I have had no signal for my TV all afternoon and evening ?
Please can you tell me what is going on ?
I live near shepton mallet, Somerset and so I presume my transmitter is the Mendip Transmitter

Rob Page:

I'm on the Mendip transmitter and there has not been any problem at all. Perhaps it is worth checking your aerial system and all the connections?

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
