Radio Set AN/URC-78 ()/(V).
Abstract
Optimization of the Phase I design of Radio Set AN/URC-78()/(V) was continued. A 11 MHz monolithic IF system, a premodulation filter, and a post-demodulation filter was constructed as part of an Operational Data System. Experimental models of the receiver r f amplifier, receiver VCO, transmitter VCO, harmonic filters and broadband antenna matching network have been constructed for the 44 MHz to 66 MHz band to support the frequency extension task. Interface systems were designed to provide compatibility with VINSON and the necessary corrections for a TOP-HAT secure transmission device containing VANDAL. A two-way demonstration breadboard for a slow frequency hopping system is approximately 25% completed. A higher power VCO and a pin diode tuned 50 watt filter are circuits under development to reduce transmitter noise.
