Freeview intermittent interference
Brian Butterworth published on UK Free TV
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 interferenceInduction interference is caused by mains-powered household devices that contain a large motor, such as:
- Washing machine;
- Tumble dryer;
- Central heating pump or combination boiler;
- 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 interferenceIf you keep a mobile phone by your Freeview box or digital television, keep it further away!
This also applies to other transmitters such as baby monitors, video senders, walkie talkies, and portable phones.
Help with Freeview, aerials?

Charles King: Since your problem appears to be a classic example of 'single source interference', you might need to hunt around some more. Apparently an AM radio can help you find the source (google within the site), but remember that it might be some equipment that you havn't thought about, or in another dwelling close to you.
A couple of years back someone had a problem with a TV, which turned out to be a duff Virgin box of the people on the other side of a flats wall.
Dont bother retuning - it just means your set will have potentially lost the transmitter. Its also worth checking your aerial cables - something with some shielding might help, but its best to hunt down what it could be first. BTW - check signal strength - could be that the signal is too strong/weak, although it would very odd to be so regular!
