N interesting method of attack against the annoyance of electrical interference has been adopted by a large organisation of 38,000 listeners in Finland. They pointed out to the power authorities that their annual consumption of electricity amounted to approximately © 2,000,000 k.w.b., -. which se ert ttl ee et te ee means a yearly income of more than £17,000 for the company. If interference from electrical appliances could be eliminated, or at least reduced power suppliers would benefit from the many hundreds of listeners who would promptly change their present battery sets (which are not so prone to mains-borne interference) for new all-mains receivers. The power authorities were impressed by the argument, and immediately responded by making a thorough investigation. It was found that about 50 per cent. of electrical interference in Helsingfors originated from lifts, and as a result of this discovery an order

has been issued to the effect that all lifts are to be equipped With interference supressors before March i, 1989. The necessary installations, which will apply to some 2000 lifts, are to be paid for by the landlords.
