Abstract

The paper describes field strength measurement sets for frequencies as high as forty megacycles. The apparatus is a double detection receiving set which is equipped with a calibrated intermediate frequency attenuator and a local signal comparison oscillator. The local signal is measured by means of the intermediate frequency detector which is calibrated as a tube voltmeter.
