Report on Test of Type RA-46125 Experimental Models of Superfrequency Radio Receivers for Single and Double Modulation. A Part of Model XAP Equipment

Abstract

The receivers were first set up in the Laboratory and given an electrical performance test on single and double modulation. For this double modulation tests it was necessary to modify a Ferris Model 18B Superfrequeny Microvolter, and to construct a modulation amplifier. The attenuator calibration of the microvollter was carefully checked to assure accuracy of test results. After the Laboratory tests were completed, the two receivers were mounted beside their respective transmitters, one in the Laboratory and on in a field test truck, and two-way communication tests were conducted over land at distances up to 15 miles. Tests were also conducted of two different types of antennas to determine their relative suitability.
