CW Applique to FM Pack Radio Sets

摘要

A study was conducted and a design selected for the fabrication of exploratory, developmental model applique units that provide a Morse-Code capability for pack radio sets. The units constructed were designed for use with Radio Set AN/PRC-10 and Radio Set AN/PRC-25, and do provide a manual Morse-Code transmission and reception capability. Signal strengths of 10 to 12 db below the minimum required for voice transmission provided satisfactory code reception. This is equivalent to nearly a 2:1 increase in range. The study also resulted in the identification of suitable techniques for high-speed Morse-Code transmissions. The development of this capability was not required by the present contract. (Author)
