Radio Interference.

To the Editor. Dear Sir, —Your correspondent, "Power Off,” in last Thursday's ” Star ” does not correctly state the case. His advice to listeners should be: “Turn down your volume control and you will not experience interference when receiving stations operating at a long distance ” —instead of “ Turn off the power,” which really means " cut off the source of current.” Inquiry has revealed that, although son?e enthusiasts own very sensitive receivers they are not content to reproduce broadcasts at moderate volume but feel they must let all and sundry, within half a mile of them, know they are operating a radio receiver. The volume control on a set is not there to be made a source of annoyance to others. It must be intelligently used. Another point that should be borne in mind by “ Pow?r Off ” is that with its volume control full on, a set is in its most sensitive condition and " interference ” that would not be audible were the control used in moderation thereby becomes noticeable. It is, therefore, not right to blame the radio inspector if he fails to locate and suppress interference with reception that is not noticeable except with the volume control full on. The remedy for the interference lies in the operator’s hands—not the radio inspector’s. In conclusion, “ Power Off ” correctly assesses the radio inspector’s responsibility, which is to do what he can to obviate interference with reception of those stations which our fees help to maintain.—l am, etc, AERIAL.
