Test equipment IE-36 reproduces the operating functions of the control boxes and jack boxes of these radio sets by providing headphone and microphone connections, thereby eliminating the control boxes and jack boxes as necessary in making trouble shooting tests and permitting such tests to be made at the point of installation of the transceiver.
The equipment comes in Chest CH-234, and includes:
BC-1303 Control Unit
I-139A Test Meter 0-lma
A-29 Phantom Antenna
CD-1169 Audio Connector
A feature of the unit is the receiver "signal source", which is a buzzer which generates wideband noise for alignment purposes.
The signal generator I-130 is probably the most useful piece of equipment. It offers both crystal and a Hartley oscillator to cover the equipment range (100-156mc). RF output is variable to a maximum of 5000 microvolts. Modulation is at 1000 cycles.
The I-95 signal strength meter is an uncalibrated vacuum tube voltmeter designed to indicate relative signal strength and the frequency of the radiation from the antenna of the radio set.
This device can also be used to indicate modulation.
