CW automatic decoding
A long press of the [KEY] button enables CW automatic decoding. Rotate the
main tuning knob to fine tune the received signal until the indicator light A
flashes in time with the code. Decoded CW text will appear at the bottom of the
screen.
■ Since the accuracy of the automatic decoding of Morse code is related to the
received station’s CW accuracy, received signal quality, and frequency
accuracy of the other radio, Auto CW decoding is only an addition to using your
own ears for decoding. It can also be useful when learning Morse code.
When using automatic CW decoding, for best results, the bandwidth of the
receiving filter should be set to 300Hz. Also, adjust the keyer speed on the
G90/S to approximately the speed of the incoming CW for the best decoding
results. The G90/S’s CW decoder is capable of excellent performance when
adjusted correctly.
