Receivers that work from bat- teries cannot be as reliable as thoad connected to the mains, for the electrical characteristics of batteries are continually chang- ing. Filter circuits, on the other hand, do not change, and, pro vided they are suitably designed, a quality of reception is possible that cannot always be obtained when batteries are used, except for the short period when the bat- teries are in new condition.

It has long been recognised that batteries are a not too reliable source of current for wireless re- ceivers, and that sooner or later receivers would be so made that users would have to connect them
