O signal Output signals from the microphone amplifier or the CW keying signal are applied to the balanced modulator 2301 pin 1 The BFO signal from the PLL unit is applied to IC2301 10 as a carrier signal C2301 is a doubled balanced mixer IC and outputs a double side band DSB signal with 40 dB carrier suppression R2303 adjusts the balanced level of 102301 for maximum carrier suppression In CW mode the CW keying signal upsets the balance to create a carrier signal In AM mode Q2302 and R2321 upset the balance to create an AM carri er signal 4 2 3 CW KEYING CIRCUIT MAIN UNIT When the CW key is closed control signal is output from CPU LOGIC unit and controls break in operation the side tone signal The input signal DOT or DAS from CW keyer is applied to the CPU LOGIC unit IC1 pins 71 70 and then CPU out puts CW control signal KDS from pin 77 The CW control signal is applied to the balanced modulator 1C2301 via 03701 03702 03701 to unbalance the IC2301 input bias voltage and create a carrier signal R3703 determines the transmit delay timing 4 2 4 IF AMPLIFIER MAIN UNIT The SSB CW RTTY 455 kHz IF signal passes through LI611 FL 65 to suppress unwanted sideband signals then the signal is applied to a transmit IF amplifier Q502 The optional CW narrow filter is not used in transmitting The amplified signal from Q502 is mixed with the 2nd LO signal and converted to a 64 455 MHz IF
