RADIO BROADCAST ADVERTISER 237 Ordinary Condenser Arrangement of Wavelenghs Ordinary straight capacity condensers crowd 70 of the 100 wavelengths into the first 30 points of the dial. Straight Line Wavelength Condenser Arrangement With straight-line-wavelength condensers 57 of the 100 wavelengths are crowded into the first 30 points of the dial. SO KARAS oP7H0^-RiccoNDENSER Arrangement of Wavelengths on Dial The New, Scientific Karas Orthometric Condensers insure absolutely equal spoaration on the dial of all wavelengths throughout the entire broadcasting range. Tuning Marvelously Simplified with Karas Orthometric Condensers The condenser that brings in KDKA where it helongs — at 53 on the dial. Remember, 52 of the 1 00 allotted wavelengths must come in below KDKA. KOiKft Note the Long Eccentric Plates Spreads Stations Evenly Over the Dial — No Crowding Whatever T HE Karas Orthometric Condenser positively separates all adjoining wavelengths by EQUAL distances on the dial, giving you the full benefit of the 10 Kilocycle frequency separation fixed by the Government. Ordinary condensers jam 70 of the 100 Government allotted wavelengths into the first 30 points of the dial — even straight -line -wavelength condensers crowd 57 of them below 30. With Karas Orthometrics, each point on the dial cor responds exactly to one of the 100 allotted wavelengths. The result is marvelous simplicity in tuning — better, clearer reception — you get all the side bands without interference. The Karas Orthometric stands absolutely alone! — an eccentric condenser, scientifically designed for present day broadcast receiving sets — the Last Word in making REAL SELECTIVITY POSSIBLE. The Karas Orthometric is a "job" that will delight the eye of the mechanical critic. It is made entirely of brass — frame and plates all die stamped — plates, patent leveled and solidly bridged to insure permanent rigidity and alignment. Every joint throughout is soldered. Grounded frame and rotor, with stator plates supported on hard rubber insulation. Tapered adjustable cone bearings, spring copper pigtail connection, automatic stops — in short, a condenser that is both theoretically and mechanically perfect.
