N2 of the TX RX unit and mixed with the 73 045MHz signal passes through LC three stage filter by O27 and O28 to generate the desired signal The signal passes through the band pass filter and is amplified by Q29 to produce the drive output which goes to the final unit from CN19 The signal is amplified to about 100W by O1 O2 O3 and Q5 Q6 Harmonic components are attenuated by the filter unit and the signal is output from the antenna connector In AM mode the signal is generated by unbalancing the carrier of SSB balance modulator ICA In CW mode the signal is input to 5 of the control unit The sidetone monitor signal is generated by IC5 and ampli fied by audio amplifier O79 and IC7 and output from the speaker CW control signal is output from IC5 of the control unit and input to CN14 of the TX RX unit to switch 025 and 026 and generate the CW signal 4 1 ALC circuit The forward wave voltage detected in the final unit passes through CN15 in the TX RX unit its level is potential dividing and it is applied to the differential amplifier comprising Q60 and Q61 When VSF is applied to the base of O60 the emit ter voltage of Q60 and O61 increases and the current flowing through the base of O61 decreases thus the collector volt age rises When this voltage exceeds the emitter voltage of 062 about 1 8V plus VBE about 0 6 the current flows through the base of Q62 and the collector voltage drops ALC time constants C an
