Build a CW Signal Processor Wiring diagram Schematic
How to Build a CW Signal Processor Circuit Diagram? That is a good question but i explain this way. This schema provides interferenced rejection for the CW operator. The 567 phase-locked loop is configured to respond to tones from 500 to 1100 Hz. The Schmitt trigger reduces the weighting effect caused by the output of the PLL remaining low after removal of the audio signal.
Ten to 15 millivolts of audio activate the schema. For periods of loss of signal, schema B will automatically switch back to live receiver audio after a suitable delay. (If a relay with a 5-volt coil is not available, the schema can also be powered from +12 volts) When schema B is used, the contacts on relay K1 replace SI.
