E FFORTS WERE MADE TO DETERMINE THE SUITABILITY OF THE ARC R-31A Glide-Slope Receiver for army use, and its advantage, if any, over the Standard A item, Receiver Group ANARA-54. The R-31A Glide-Slope Receiver is a lightweight, commercially available set designed to operate over the range 329.3 - 335 mc, with 20 channels spaced every .3 mc. The receiver is of modular construction and employs a double conversion superheterodyne circuit. The circuitry includes the use of t e printed-circuit technique, of transistors an crystal diodes, and subminiature electron tubes. The tests indicated that 1 the performance of the ARC R- A Glide-Slope Receiver is equivalent to that of Receiver Group ANARA-54, and 2 the ARC R-31A GlideSlope Receiver offers a substantial reduction in weight size, and power requirements over the present Standard A Receiver Group anara-54.
