The beauty of the K3NG schematic is its modularity. You can add:
This circuit often uses a switching transistor, such as the 2N2222 , or an optocoupler to isolate the keyer from the radio’s circuitry. k3ng keyer schematic
Note: Pin assignments can be customized in the firmware's keyer_pin_settings.h file, but these are the standard defaults. Output Connection (The Transmitter Interface) The beauty of the K3NG schematic is its modularity
Let’s explore each section as it appears in the standard schematic. such as the 2N2222
The true strength of the K3NG keyer is its modularity. You can expand your schematic to include:
