Interference tips for those suffering.

General tips for interference sufferers.
It is important to remember that most cases of interference are not caused by a faulty transmitter, but by poorly designed home electronics equipment. However, there are steps that you may be able to take to minimise the chances of the problem occurring.

Attitude. Please do not go to the neighbour, screaming and blaming them... this may lead to them taking a defensive position and telling you where to go. Do try to reason with the person.

Your system.
As noted above, much interference is due to poor quality consumer electronic equipment. Most manufacturers will cut corners wherever possible, as they are competing on price not quality.
Also, when testing a design, manufacturers may not be running them in the same conditions as you will be - they may never see some "bugs" in their design.

Non-radio equipment.
If the equipment suffering is not designed to pick up radio signals, then the fault is probably in the equipment suffering the interference. Such equipment should not pick up any radio signals.

Television.
Much of what appears to be interference may be due to weather conditions, faulty antenna or poor connections. Indoor TV antennas are also prone to problems, as will be any system where the reception is poor to begin with.
Check these first, and make sure that you have a strong signal.
If you have a good signal, and are certain it is a local CB interfering, you can connect a low-pass filter in your TV coax. The best ones are the braid-breaker type.

Tips for them.
If you are on friendly terms with your neighbour, it may be helpful to explain the situation to them. You may wish to print off the two interference pages in this section, so they may check their system.
Any problems they have which cause interference may also reduce the performance of their CB equipment... it may even cause damage. So it is as much in their interest to check it over from their end.

Amateur help.
If you know a local radio amateur, with a few years experience of radio, they may well be able to help with advice specific to your situation or even filters at a minimum cost.

Professional help.
If the problem cannot be resolved, you may be able to get help from your local electrical dealer or electronic engineer. They will charge for this service, and will most likely just fit the filter mentioned above - and relieve you of a load of cash for the call-out, time and filter (at their price).
With this in mind, it really is better if you can get it sorted between you and the neighbour.

Official help.

Can Ofcom refuse to help? Absolutely. They will not get out of bed for problems with MW (AM) radio, baby alarms, non-radio equipment (such as CD players or telephones), TV using set-top antenna, and possibly some other devices. They may also refuse to investigate if you have not already tried getting help from a local dealer or engineer - they require proof on the application.

If the problem cannot be resolved, you may be able to get help from Ofcom. First of all, before they will consider looking, you must have already tried getting the help of a dealer (see above).
It should also be noted that they also have a charge, unless the transmitter causing the problem is illegal or you get a free TV licence.

What Ofcom will do for their bung.
In most cases, the investigation service will simply fit a filter. If the offending transmitter is illegal, it may be confiscated. If there is enough evidence for a successful conviction, then the offender may be taken to court.
Court action has always been incredibly rare (count them on your fingers), with some written warnings and mostly verbal warnings given. However, if they take court action, they love to boast of their 100% conviction rate.
There are plans to remove the need for court action by giving out fixed penalty notices. More about this can be found in the news section.
