Abstract
PURPOSE: To ensure the frequency calibration with a simple constitution by receiving the signals of the known frequency, securing the digital display of the frequency and adjusting the optimum tuning position via the IF transformer.
CONSTITUTION: The signal whose frequency fA is already known is received, and the tuning operation is given so that the accurate digital display may be secured for received frequency fA through indicator 12. When the tuning operation is over, tuning idnicator 10 indicates the position which is shifted a little bit from the optimum tuning position. Then IF transformer 6 is adjusted while confirming indicator 10 so that the optimum tuning position may be indicated by indicator 10. Thus, the frequency calibration can be performed through a simple constitution.
