WebThe 80m SSB & CW transceiver design is based on an already proven concept used in ATLAS amateur transistorised transceivers from 70's. The "two-mixer + 1 XTAL filter" design uses the 1st mixer as front-end mixer on receive as well as SSB modulator on transmit. WebTablemodel with Push Buttons.

WebIn CW mode a 1k resistor is used for carrier through. The preamplifier of the electret microphone uses a low noise op-amp TL081 (U3). The DSB signal from the modulator is amplified by a monolithic amplifier U9 ( MAR-6 ) and routed through the SSB filter CFJ455K filter, which is the same filter used on the receive path. WebCW operation: Sine wave tone around 900 K.C from an oscillator consisting of Q13 and Q14 is fed to mike amplifier through SW1, SSB/CW switch in key down condition. At the same …
