Portable VHF Receiver/Tape Recorder Calibrator

Abstract

A calibrated VHF/FM source for use in correcting tape recorder and receiver errors which consolidates these functions in a lightweight rack using commercial test parts and maintains a high precision of accuracy by having the system monitor its own output and correct the distortion and amplitude errors attributable to the nonlinear behavior of the Voltage Variable Capacitance diode (VVC diode) of the Voltage Capactive Oscillator (VCO) of the VHF FM transmitter.
