WebFunctionally Incomplete - Transmit only and/or typically limited to CW Morse code rather than SSB voice.: Restricted frequency operation - Crystal frequency controlled, or limited "VCXO" frequency range (e.g. < ±500 ppm = ±1.85 kHz @ 3.7 MHz).: Overly ambitious - Excessive component count, mechanical complex, too many features and functions … 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.
