Freeview intermittent interference

When you get occasional sound loss or picture freezes

^{Brian Butterworth published on UK Free TV 20th September 2007 at 10:52}

There are several different types of interference that cause problems. This page deals with the situation where:

Freeview reception is perfect or near-perfect most of the time
The audio on TV and radio channels mutes momentarily a few times each minute
The picture on a Freeview channel freezes a few times each minute

There are two main causes of this type of intermittent interference:

'Induction' interference
Mobile phone interference

Induction interference

Induction interference is caused by -powered household devices that contain a large motor, such as:

Washing machine;
Tumble dryer;
Central heating pump or combination boiler;
Fridge;
Freezer;
Power tools (drills, jigsaws etc)
Vacuum cleaners;
Water pumps;
Automatic doors

You can identify if one or more of these devices is causing the Freeview reception problem by powering off the devices.

If one of these devices is causing the problem, then the reception problem can usually be solved by using a mains filter device and use it on the Freeview boxes mains connection.

Such as device is this: Maplin: 6-Way Flat Screen and HDTV Surge Protector and Mains Filter.

Mobile phone interference

If you keep a mobile phone by your Freeview box or television, keep it further away!

This also applies to other transmitters such as baby monitors, senders, walkie talkies, and portable phones.

Geoff. Doxon: If your question relates to when the Kendal at Oxenholme may transmit all , then I imagine that it's extremely unlikely. A few transmitters became full service when TV transmitter frequencies were reorganised to clear the top ones for use by mobile phone .

My cursory familiarity with the Kendal area is that the transmitter is receivable in some places, this judging by the Freeview predictor and the fact that some houses have Lancaster aerials.

Lancaster carries BBC One North and ITV , whereas Kendal (Oxenholme) carries BBC One North West and ITV Border, so if ITV Border is important to you then a two- approach may be the way to go.

That said, as Lancaster is possibly out of sight or not far off, may be expected to not be as reliable as Kendal or . Thus, with an aerial on Lancaster and one on Kendal (or Kendal Fell, depending on which is best), it may be preferred to rely on Lancaster only for the channels that one of the Kendal transmitters doesn't carry.

Why is our for Cardiff and the Vale of Glamorgan, going off between 12.30/13.30 until 19.30 each day.

If they are working on transmitter, when will work finish, and what are they doing?

Nigel Haigh:

There are many transmitters having Planned or Essential and Arqiva never give the details about the work or how long it may last.
It is unusual for any (which we assume may be a rather than a main transmitter) to go off for such lengthy periods in daytime, but it does happen occasionally.

Is it all going off, or just some? Eg. just ITV/C4/C5 etc or just BBC channels.
I you are not trying to retune when the signal goes off and it says "" - you cannot tune to signals that aren't there, it will usually just clear your correct tuning.

I can't find any current warning from the BBC about such lengthy interruptions for any transmitter but I'm afraid without the specific transmitter name or your full postcode to check which transmitter you may receive, we can't look to see if any further information may be available.
