CHANGE IN AERIALS

EFFECT OF SCREEN-GRIDS LOOPS BECOME POPULAR The screen-grid valve is largely responsible for a change in aerial requirements. Many receivers on the market now are capable of receiving local programmes without an aerial, or with a few feet of wire at most. These same receivers, operating from a wire around the picture rail, or a light socket aerial plug, generally have an excellent range, comparable, in fact, with the average properlyerected outside aerial. This great increase in set sensitivity, due to a large extent to the use of the screen-grid valve, is having a marked effect upon metropolitan aerial requirements. Owners of screen-grid sets are finding reception quite satisfactory with a small aerial, and are coming to prefer it to Lhe clumsy roof aerial. With simple sets and in country localities the aerial will probably remain essential to satisfactory operation, at least for some time to come. In metropolitan areas, however, it is not unlikely that the outside aerial will slowly become a. thing of the past.

REMOTE CONTROL TUNING-IN FROM DISTANCE WORKED FROM ANY ROOM Remote control tuning, which enable: a radio set owner to tune the set without direct hand manipulationof the dials, is introduced in several of the new receivers. The set can be controlled from across the room. Representing the essence of comfort and convenience, the new auto—matic remote tuner enables the operation of the radio set from any room in the house. No longer is it necessary to leave a comfortable chair in order to obtain a change of station or to put the set in or out of opera-tion. A mere touch of a. button on the automatic remote tuner brings in stations like a. flash—automatically. To turn the set off is just to press another button. A small control knob automatically regulates the volume, disengaging the volume control on the set itself for remote operation. FOR ANY ROOM Any number of remote tuner uni-ts up to four can be connected to the set. Any room can be equipped with one so that operation of the set can be enjoyed throughout the entire house Without having to go to where the set is located to change stations. Fifty feet of cable, which lies unnoticeable under the rug, is furnished with the remote tuner, but longer lengths may be had and used. The automatic tuning device on the set is equipped With an automatic station indicator and silencer. The indicator shows a small red light above the station recorder, showing at all times the station then being heard. The silencer is designed to automatically eliminate all in be—tween station noises When changing from one station to another.
