Sounds like interference. Maybe something that comes on at night?

Robert: Everyone's case is different depending on their exact location. Signal levels can vary greatly over just a few metres - good positioning of the aerial is important. How important it is, is down to the actual signal levels available: in areas with high field strength, and low or no co-channel interference, it's not important; in areas with high levels of interference, it's very important.

Signal levels vary with weather conditions. TV signals behave like light - they reflect, they refract, and they can be selectively absorbed by the atmosphere, depending on the amount and size of particles (dust, raindrops). The transition from night to day and day to night usually sets up different layers of warm and cold air, and signals can bounce off the boundaries between these layers rather than passing through, usually called 'tropospheric enhancement'. Less-common conditions, like extensive high pressure, can cause layers where the signals bounce along between upper and lower layers, exiting a long distance from the transmission point: this is usually called 'ducting'. Generally this increases the level of interference: if you don't have enough signal margin, the difference between the level of the wanted signal and the level of the interference, it causes the picture to break up. The distance between transmitters using the same frequencies is far enough apart that, for people in the expected coverage area, changes in weather conditions shouldn't cause problems 99% of the time.

The old advice to retune if you had a problem was because a number of boxes had buggy software that would corrupt their own settings over time. Resetting to factory defaults and retuning restores a good set. However, that advice is flawed after switchover, because so many boxes will happily store distant signals that are too weak to be reliable. I now tend to advise manual retuning if the person with the problem is predicted to have good enough signals. Only after confirming that the box has actually tuned to the correct transmitter is an aerial check indicated.

There are some boxes, however, which have no manual tuning functions. I was reading a TV manual a couple of days ago to try to help someone - can't recall which brand - that had manual tuning for analogue, but not for digital.

Equipment that's now on the market is *supposed* to tune to the best quality signals available, and if it detects more than one region, it's supposed to ask which one you want to store. However, I'm aware that the Humax Freeview HD equipment still doesn't do this correctly.

Retuning when you have a problem, and that problem is caused by higher-than-normal levels of interference, is likely to cause many boxes to store services from the wrong transmitter. In the wrong conditions, even those that normally do it properly might get it wrong, if the wanted signals are particularly badly affected.

For your particular case: make sure that your receiver is correctly tuning into the Oxford transmitter. BBC One (logical channel number 1) should be found on UHF frequency C53, ITV1 (LCN 3) on C60, ITV3 (LCN 10) on C62, Pick TV (LCN 11) on C59 and Yesterday (LCN 12) on C55. If that isn't the case, see Digital Region Overlap for ideas on how to make it do it, or replace the box with one that does it right.

For you, a box that stores the first version it finds could well pick Oxford for the BBC, but Mendip for all other services, if the Mendip services are strong enough to be decodable at all.

If it is definitely tuned to Oxford, then you should be looking at aerial problems. Looking at that postcode, there appears to be a stand of tall trees to the north-east of the buildings, which would be approximately in the direction of the transmitter. You may find you get better results if you can aim the aerial between the trees, or if you can get them reduced in height so the aerial can look over them.

You've posted before that you have multiple aerials for multiple TV points. You're likely to get more consistent results from one well-placed aerial, with the signal being distributed to the TV points. Look for installers specialising in MATV (Master Antenna TV) or SMATV (Satellite + Master Antenna TV) systems. The installer should ensure that the signal levels at each TV are adequate to ensure reliable reception.

Have been away since 10 April, so have only just checked the post-April 18th situation - all my channels seem fine (SN7 postcode) but have just realised that I don't have Channel 62 (TV Stars) on my digital tv downstairs, although it appears through the set top box connected to my tv upstairs. Not that there is anything on Channel 62 - it just says "coming soon". Very odd. Ihave all the other channels I am supposed to have and good signal strength as well.

Does anyone remember the days when we all watched analogue with only a few channels but no problems at all........?? Wasn't it great! No problems with adverse weather conditions, or picture breaking up, or no signal and just a simple aerial... I could go on, but I won't.

Tigminor; EPG programme channel 62 is on mux channel 59 from Oxford, and so if no actual programme is seen on the other TV either then it suggests that the programme hasn't actually started as yet, as Pick TV on EPG 11 and Dave on EPG 19 is on the same mux transmitter as Stars TV on EPG 62.

You should check with someone else local to you, as I have no way of verifying if the programme is operational as yet, but have you carried out a factory reset before re-tuning? as that's always advisable as it gets rid of any corrupted data that might be stored in the memory.

Regarding analogue, yes!! it did have a certain robustness attached to it that digital TV most certainly does not have, basically because of its reception threshold level whereby that under a certain signal strength it cuts off completely, unlike analogue that could slowly vanish into the background speckles.

jb38: Many thanks for that. I can get both Pick TV and Dave - and when I checked on my digital tv this morning, TV Stars is now there as well, though it has not actually started yet - coming soon. So it looks as though all is well. I probably won't want to watch it anyway - I just wanted to make sure I actually receive everything I am supposed to!! I will also remember your tip about the factory reset in case of need. Thanks again.

Tigminor: Yes, you have nothing to worry about as you are not missing anything, matter of fact I carried out a check on my own TV earlier on and found that "TV Stars" was one of three new channels found, and of course with the "coming soon" caption appearing (albeit sluggishly) exactly as you have described.

Well a different problem last night, although similar time. My bbc3 was freezing even though bbc 1 & 2 were fine.

I also noted the comments about C62. according to the list and my set up C62 is active with the '5's, ITV3 etc.

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.
