Judging from the comments in recent postings, I am not the only one whose TV reception quality is being affected by weather related co-channel interference.
The clue to this type of interference is a strong signal associated with a very high error rate as reported by the signal quality display.
In my case such interference is at its worst just after sunrise and during the morning. As I reported in my earlier postings, the interference is mainly confined to CH27, which means I lose all the BBC channels.
Retuning when this happens, results in the TV finding the BBC mux from Belmont, which I assume is a normally weak signal, received from the side or back of the aerial.
At night signals from Sandy tends to recover and I see messages reporting "New Service Found".
It is interesting that for 30+ years I received TV signals from Sandy without any problem, except under extreme high pressure lift conditions. Now we have digital TV, the channel planning is so bad, Co-channel interference is common. Could it be that pressure from Government, keen to sell off RF spectrum, has resulted in too few channels being allocated to poor old Free-View?

jb38: it rained yesterday, thunder storms , and heavy down pour....... i had all my stations !!! everything worked , no breaking up etc etc perfect picture...............turned tv on this morning, lost Pick TV again saying no or bad signal or this station my be scrambled. also lost Really tv, Yesterday keeps breaking up, weather today has been light showers, but mainly sunshine, seems i need it to constantly rain for to get a perfect picture with no lost of viewing at all :( i guess i will just have to resign myself to miss all my favourite programs. i will check again in a few days to see what the signal is like, but i wont keep messing around with it. thats it now, thanks again to all that has tried to help, seems like my only option is Virgin ir Sky and i cant afford either lol xx

Suzy: Why dont you opt for Freesat? as once the cost of the box has been paid for plus the fitting of the dish, then you will have ultra reliable reception for ever completely free of charge.
Dish kits (complete) can be obtained for as little as just over £30.00 or so from numerous e-bay outlets, and all you would then require is someone to install it for you.
By the way as far as your reception is concerned, rain clouds can on occasions assist Freeview reception dependant on their height, and caused by them reflecting terrestrial signals into areas that would normally be bypassed by the signals heading skywards.
Of course on the other hand, the very same rain clouds if of a really heavy thundery nature can block satellite reception for a minute or so, because microwave signals cannot pass through an intensely watery cloud any more than they can be received under water.

jb38: cant afford freesat, and like sky it is not good as there are trees around my garden ( council property ( so i cant cut them down, sky say there is no line of sight, ie trees blocking signal , which i already knew as being an ex sky employee, had a fantastic picture earlier then it rained :( all broke up then it stopped raining, it was fine, not its raining again, lost the picture l going to go and stick a huge umbrella over my aerial lol see it that makes a difference ! x

Suzy: With regards to not being able a have a satellite dish because of the trees blocking the signal, have you just been told this as a result of an enquiry? (no matter who you addressed your enquiry to) or was this what you were told by an engineer "after" having carried out a test? as although the image I am looking at is about three years old the angle of obstruction to the satellite position that I see "might" just be able to be cleared if the dish was mounted at near to gutter level.
This being said based on the fact that the dish when mounted on the rear of the building would be facing slightly to the left, and also on the assumption that you reside about the fourth property down from the start of the row, and not right next to the end where the other row adjoins at right angles.
Just really asking out of interest, and by the way I only mentioned Freesat as it is truly free, whereas Sky only is if you can get hold of an old box and have someone install a dish for you.

jb38: hi, i had an engineer out when i first moved in, am i in a ground floor council flat the woman who lives up stairs also wouldnt let me have a dish put on "her property" as she put it as she owns her flat up stairs, so my dish would have to be low and around the back of my property, I am in the property that adjoins at right angle lol, tipical isnt it, ive given up trying to watch my stations now i even just tried to watch a film on film 4 and it keeps breaking up, same with a few other stations now, may aswell get rid of my tv , as it will save me money not having to fork out for a tv licences for something i cant watch half the time, thanks for all your help and advice, time to get rid rid of tv !!!!

You're not the only one having the same problem with channels breaking up, not getting a signal.
NN169LG is my post code and getting the same results as Suzy is.
All tv's in the house are getting this problem, two of the tv's are brand new. Nothing is wrong with any of the boxes.

Suzy: I was beginning to have a sneaking suspicion that the property Google earth was indicating as corresponding to the code provided was possibly inaccurate as the whole row most likely uses the same postcode, however now you have said that you are in the corner position then I fully understand why satellite reception is out of the equation, as that particular position is almost completely shrouded by trees.
Before you give up though there is one final thing you could try and at no cost to yourself provided that you carefully remove it from its packaging without damaging it as it "is" a returnable item, the item in question being a signal booster sold by Argos item number 534 / 4235 and as seen on page 565 of the latest catalogue.
Admittedly I do have my doubts about exactly how effective it will be in your particular situation where fluctuations in the signal level are so commonplace, and I only really suggest trying because its known to be feeding into a box with a stable tuner, i.e: the Humax, but though a device like this can be easily adjusted to keep the signal received running high enough to keep it well away from the lower threshold reception level which should (in theory) help kill off some of the glitches you are experiencing, as boosters "do" serve a purpose albeit that they might well be seen demonized in certain places.

Sam: Out of interest where exactly are you receiving your main signal from? as on the property with a satellite dish mounted on the chimney stack I can see one aerial pointing at Sandy, another at Waltham, and an FM aerial that "appears" to to facing towards Sutton Coldfield.
