INTERFERENCE WITH OTHERS Every user of a valve set knows what it is for a programme to suffer interference from a constant high-pitched whistling note. This whistle may be due to the fact that another station is working on a wave-length that is rather too close, or it may be caused by misuse of the reaction knob in your own set. You can easily tell whether you are responsible for the whistle or whether it is due to interference with stations. Just turn the tuning knob of your set slowly to and fro over two or three divisions. If the whistle does not change its note, but simply becomes softer or louder, then you are not causing it, and you cannot do anything to 6top it. But if, as you move tlie knob, the note runs up and down the scale, then your set is oscillating, and you must immediately move the reaction knob in a counterclockwise direction until the whistle stops.

It should not be forgotten that if you let your set oscillate you can interfere with the reception of all listeners within a radius of a mile or two who are trying to hear the station that your set is bringing in. Make it a rule always to keep the reaction knob turned as far anti-clockwise as you can without losing signal strength, and never turn it so far clockwise that the set howls and squeals.

VERTICAL AERIALS.

USE FOR SHORT WAVES.

Because most short-wave enthusiasts who listen in on tlio short-wave couple their short-wave set to their regular broadcast aerial, which is usually ot the long horizontal type with a vertical lead-in, they find the programmes marked often by fading. While short waves may inherently fade to some extent, much of this is due to the receiving aerial used. Vertical aerials are now being erected by high-powered broadcasting stations for transmitting purposes. This same type of aerial should be used to eliminate much of the fading now experienced on the short waves. Incidentally, the vertical aerial makes for a much neater job on any house, and in many instances simplifies the erection, since the long stretch of the ordinary flat top demands two points of Suspension, well apart, with resulting guying. A vertical aerial is practically the ideal lead-in. When erecting such an aerial it should be kept a couple of feet away from any structure. In order to obtain this condition it may slope a bit upward and then connected to a short cross wire running from tree to house, care being taken, however, that the vertical portion is completely insulated from the flat portion, which merely becomes a supporting wire for the vertical aerial. NOTES AND COMMENTS. Tho international radiophone service was utilised recently to transmit round the world a gramophone record which was broadcast by Amalgamated Wireless station 3ME, Melbourne, and received back there again after travelling a distance of about 21,500 miles. Tho experiment originated with Mr. E. 11. Scott, a wireless expert of Chicago, by whose request tho Melbourne station broadcast the record. Immediately tho record commenced Mr. Scott, who was in touch with 3ME by international telephone, remarked, " That's fine, I can hear you perfectly. I will put your transmission back to you." Mr. Scott then connected his station by land line to New York, thence tho transmission travelled by air lino to London, thence to Sydney by air line and finally by land lino back to the point of origin at Melbourne, where it was received with good volume and clarity.

A bill directing the Federal Radio Commission to report on the of Government ownership of broadcasting was passed recently by the United States Senate. Tho move followed a warning issued by the commission that listener goodwill should not be sacrificed to excessive commercialism. In discussing the problem of radio advertising, the commission pointed out that tho rights of 123,000,000 American persons in broadcasting cannot bo denied. Its report stated" And if their share of this form of entertainment can be received only at t.ho expense of advertising statements or claims, which are false, deceptive or exaggerated, or at the expense of programmes which contain matter which would be commonly regarded as offensive to persons of recognised types of political, social and religious belief, then they are justified in demanding a change in the system.''
