The modulation signal is also fed to VC terminal through IC5 The frequency adjustment is achieved by switching the ratio of dividing frequency that is not adjusted by the DC voltage impressed to VC The resolution of the adjusting fre quency is approximately 8Hz Because twice the VCO out put are input for the input frequency of PLL IC the sending and receiving frequency can be adjusted by approximately 4Hz resolution 5 2 VCO There is VCO and TX VCO The TX VCO Q10 generates a transmit carrier and the VCO 08 generates a 1st local signal For the VCO oscil lation frequency the transmit carrier is 136 to 174 MHz and the 1st local receive signal is 194 05 to 232 05MHz The VCO oscillation frequency is determined by one sys tem of operation switching terminal T R and two systems of voltage control terminals CV and ASSIST The operation switching terminal T R is controlled by the control line T_R output from the ASIC IC108 When the T R logic is low the VCO outputs the transmit carrier and when it is high it outputs a 1st local receive signal The voltage control terminals CV and ASSIST are controlled by the PLL IC IC3 and ASIC 108 and the output frequency changes continuously according to the applied voltage For the modulation input terminal VCO_ the output frequency changes according to the applied voltage This is used to modulate the VCO output VCO MOD works on
