Test of Radiomarine Corporation of America Receiver AR-8503, Serial 3922

Abstract

The receiver was given a general inspection of mechanical construction and wiring. The following electrical tests were made: (a) Sensitivity. (b) Selectivity (strong and weak signals). (c) Maximum noise level. (d) Resonant overload. (e) Volume control characteristics. (f) Volume control range and linearity. (g) Audio amplifier characteristics. (h) Main tuning calibration and determination of frequency overlap between bands. (i) Accuracy of resetability. (j) Measurement of battery drain. (k) Frequency stability for changes in battery voltages. (l) Time constant of unblocking from strong cw signal. (m) Radio frequency radiation. (n) Output impedance characteristics.
