Selectivity e Twoer

11 is a well known fact that a superrengen receiver is sensitive. However, it is also extremely broad. Four or five signals will cover the entire two meter band. A receiver of this type can be made selective, In fact, the selectivity can be made almost equal to that ot a superbet and with far less tubes. Approximately thirteen years ago, experiments were made with a coaxial tank input circuit having a bandwidth sharp enough to receive two signals only 30 kc apart in the two meter band. The 6AK5...

Electronic Servicenter Of New York

Y. W ith the very low tuning rates of many modern receivers, the laboi of tuning from one end of the dial to the other is considerable. If, as is often done, a subsidiary planetary drive is added, the operator may come down with 'nailers wrist as a result of tuning across the band too many times in succession. What is needed here is a simple motor drive to save wear and tear on the operator s wrist. Only a few modern receivers are so designed that a Zenith...
