Model LM Radio Frequency Measuring Equipment - Manufactured by Radio Research Company
Abstract
These tests were conducted to determine the mechanical and electrical characteristics of the Model LM frequency measuring equipment as well as how suitable it may be for installation and operation in the Naval aircraft service. The model LM frequency measuring equipment does not entirely meet the requirements of the governing specifications. These tests covered the following: mechanical workmanship, size and weight, materials, mountings, controls, frequency ranges, power output, audio beat frequency, radio frequency, RF input required to produce the specified audio output. Frequency stability under conditions of variation of receiver volume, change from transmit to receive position, 10 percent change in supply voltage, reset from calibration, variation of ambient temperature from -30 deg to +50 deg C, and vibration. Tests of power supply including source, dynamotor regulation, ripple, and improper filtration.
