Breakthrough from radio transmissions

Although breakthrough can be heard as a wide variety of noises, the most common effects are distorted speech or rhythmic thumps and pops being heard over the radio. It may be accompanied by whistles or warbling. Sometimes these sounds can be heard on other equipment such as cordless phones, baby monitors, hi-fi equipment, computer speakers and even hearing aids.


Domestic electronic equipment such as radio and HiFi aren't designed to pick up non-broadcast transmissions such as radio communications. If there are no transmissions nearby, there is normally no problem. However, if there are nearby transmissions, and the equipment hasn't been designed with good immunity to these signals, they can 'break through'. This is more likely to happen if your equipment is damaged or poorly installed.  It is very rarely the result of a faulty transmitter.

It is not always simple to establish how resistant your equipment is to break through interference. Equipment now has to conform to regulations designed to protect against breakthrough in a typical domestic setting. You could talk to a local dealer for more advice. 

Who is responsible?

If someone has begun using a transmitter in the near vicinity, and you are suffering disruption as a result, it is not necessarily their ‘fault'. Provided they are operating within the terms of their licence, they are generally under no obligation to change or curtail what they do in order to avoid causing breakthrough to neighbours' equipment.
