Gordon Britton,Mark S,Andrew Clarke.One possibility here is atmospherics or inversion effect as at this moment in time here in Halifax HX2 9JY while im typing this text to the above affected people,i am watching the Chelsea v Napoli football game on fuzzy snowy analogue ITV1 on three different South East England transmitters,Crystal Palace London Carlton/LWT on ch 23,Heathfield Meridian Maidstone on ch 64 and even Dover also Meridian Maidstone on ch 66 (All with and without signal amplification as such).These analogue transmissions travelling to my location can still occasionally occur but hopefully once analogue in the UK (TV analogue that is) ceases by Wednesday 24 October 2012 all digital TV transmissions after this date will suffer less interferences as such and possibly even disappear altogether but it is not guaranteed as such !

If i may add briefly it is atmospherics/inversion at work not any faults from any transmitters as such !

Pat chittenden: There is unfortunately nothing you can do about this as its basically caused by the atmospheric conditions that are presently applying, if you had refrained from carry out a re-tune it would have only have been a simple case of checking now and again to see if the situation had improved any, whereas now you have re-tuned you will have lost them, this meaning that you will now have to carry out frequent re-scans to pick the channels back up again.

To be quite honest about it, on checking your reception possibilities it doesn't appear that you will really have good reception from anywhere before June 27th, as then the transmitters that cover your area (Dover and Ramsgate's PSB only relay) will be switching over to higher powered operation.

Hello, Looking for help to solve a persistent interference problem on my Samsung D6530 set. Location is PE10 0AF. Aerial is 28 element DMX type aerial tuned to Waltham transmitter. Problem started about 6 weeks ago and is characterised by pixellation & loss of signal approx every 6.5 minutes. When problem is not present signal strength & bit error levels are 90% & 0 on Channels 29; 61 & 54: 74% & 0 on Channels 56 & 57 and 42% & <180 on the HD Channel-58. I have repeatedly auto-retuned all channels & three days ago manually tuned all six of the Waltham multiplexs, without any improvement to the problem.
I have also checked for any internal sources of electrical interference (c/h boiler, fridge, transformers etc) and still could not obtain any improvement. Any ideas on where to go next would be greatly appreciated?

MikeW - Is that an incessant and little varying 6.5 mins, or do you have periods of good reception?

Do you have neighbours to compare notes with?

Are you using an amp of any sort? Worth trying one if not - they are cheap, and you may be able to return of not needed.

For the last year or two we have suffered occasional blocking interference and 'No Signal'on channels 3,4,5,9,10 and others. This is now becoming very regular usually commencing about 8.30pm and clearing about 9.30/10.00pm. There does not appear to be any connection with the weather or time of the year - it is just very annoying and spoiling our evenings viewing. We have checked with other people tuned to the Hastings transmitter in our area (Hellingly East Sussex)and they have the same recurring problem. Will this improve after the switchover or will we have to make some other adjustments?

MikeW: This type of problem can only really be caused by interference being picked up either via the aerial or alternatively from the mains supply, and this not necessarily being from within your own property.

A good way to test for the latter is if you have a small portable radio of the slightly older variety that has long and medium wavebands (particularly LW) is to switch the radio on and tune it away from radio 4 where no stations exist, then with the volume turned up slightly position the radio close to any mains socket or a cable coming from, then when you see the problem on the TV move the radio about as close to the socket as possible and listen if you can hear noises corresponding to the problems with the picture, if you do then its a mains borne problem.

Should though it prove as not being, then although its something that lots do not like doing, but you really have to know if anyone else locally (a neighbour) is suffering from similar problems, as the cause of this annoyance may well be totally outwith your control.

Although I am acquaint with your village by having passed through it on a number of occasions recently I cant remember if your electrical supply is via overhead cables or not? as should it be then these cables are great for picking up impulse interference along the way.

Anyway, if at all possible try the radio test, and by the way this device is also excellent for sniffing out interference from all sorts of domestic appliances such as the types you have mentioned plus sewing machines / food mixers / electric bread knives / hair driers / vacuum cleaners and a multitude of other gadgets that use "brush" type motors.

MikeW: Of course all that's been mentioned is not really taking into account that the fault "might" be originating from within the TV itself, but you can soon prove this (or not) by temporarily trying another set in the same position, or of course just asking a neighbour if they are having problems.
