Abstract:

A calibrated VHFFM 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.
