Description

U.S. Army Signal Corps Radio, Receiver (R-174/URR), Power Supply (PP-308/URR) and Cabinets (CY-615/URR).
Order no. 15166-PH-52, serial no. 2465, Motorola Inc.
Affectionately known as the "Angry 5," the AN/GRR-5 compact mobile shortwave receiver was used in the United States military during the 1950s and 1960s.
The complete radio consists of two chassis: the model R-174/URR receiver and the model PP-308/URR power supply. The two-compartment cabinet has the model number CY-615/URR.
This radio covers 1.5 Mhz - 18 Mhz in four bands. The smallish tuning dial is located above and left of the tuning knob. On the left are large connectors for antenna and ground, the RF gain knob, and the four-position bandswitch. The antenna trimmer knob lies left and below the tuning knobs.
At upper right is a Monitoring Input connector with removable cap. To its left is a four-position mode switch (PHN, CW, NET, CAL). Just below are two Phones connectors, also with removable caps. The BFO and AF Gain knobs are located at lower right, and nestled between them is a two-position output switch (LO/HI).
In the center of the lower power chassis is the rugged little speaker grille. To its left are two jacks with removable caps. The upper one is for connecting a dry battery cable; the lower one is a container for spare fuses. The fuse caps themselves are located in a row along the bottom.
At upper right is the Power Input jack for connecting an AC or non-battery DC power source. To its left is the speaker on/off switch, and below it is the main power switch. Left of that is the four-position Power Selector, with positions for 6V, 12V, 24V, and Dry Battery. A legend on the front panel notes that changeover to AC power is automatic. A thick rubber-coated cable connects both chassis when they are installed.
Heavy spring-loaded clips on each side hold the chassis securely in each cabinet.
Radio appears to be complete but is being sold as is. I have no knowledge as to if or how well it works.
Thanks
