(XC-3), an FM Radio Transmitter T-30/TRC-8 (XC-3), Power Pack PP-1l5/TRC-8 (XC-3), two Antenna Assemblies AS-52/TRC-8 (XC-3), two 40-foot Antenna Supports AB-48/TRC-8 (XC-3), one Power Unit PE-75-( ), and spare parts for maintenance.  This equipment is intended for point-to-point or radio-relay application to provide either single or multichannel communication in both directions simultaneously. Spare components are not included in Radio Set AN/TRC-8 (XC-3) as it is not intended for continuous uninterrupted operation. The reliable range is 25 miles over flat terrain. Satisfactory communication can be attained as far as 100 miles when advantage is taken of high points in the terrain and when a line-of-sight path exists between transmitter and receiver. The equipment is solidly built and is intended for use as a fixed field station and not for mobile operation. All components are transportable in a standard military 3/4-ton truck or 1-ton trailer. The radio set may be installed by a crew of four men in approximately 1 hour after arrival at the operating site if the equipment has previously been removed from any packing cases. It has been designed with excellent frequency stability, sensitivity, and all operating characteristics necessary for long, reliable service under conditions of relative humidity up to 95 percent and temperature variations from 40C to +60C.

Overview

Radio Set AN/TRC-8 (XC-3) consists of an FM (frequency modulated) Radio Receiver R-48/TRC-8 (XC-3), an FM Radio Transmitter T-30/TRC-8 (XC-3), Power Pack PP-1l5/TRC-8 (XC-3), two Antenna Assemblies AS-52/TRC-8 (XC-3), two 40-foot Antenna Supports AB-48/TRC-8 (XC-3), one Power Unit PE-75-( ), and spare parts for maintenance. This equipment is intended for point-to-point or radio-relay application to provide either single or multichannel communication in both directions simultaneously. Spare components are not included in Radio Set AN/TRC-8 (XC-3) as it is not intended for continuous uninterrupted operation. The reliable range is 25 miles over flat terrain. Satisfactory communication can be attained as far as 100 miles when advantage is taken of high points in the terrain and when a line-of-sight path exists between transmitter and receiver. The equipment is solidly built and is intended for use as a fixed field station and not for mobile operation. All components are transportable in a standard military 3/4-ton truck or 1-ton trailer. The radio set may be installed by a crew of four men in approximately 1 hour after arrival at the operating site if the equipment has previously been removed from any packing cases. It has been designed with excellent frequency stability, sensitivity, and all operating characteristics necessary for long, reliable service under conditions of relative humidity up to 95 percent and temperature variations from 40C to +60C.
