Welcome to the CWTY
program. This software is designed to allow CW operators
to see coded signals as text CW from their receivers and
to transmit CW using the serial port or sound card of
the computer. This is accomplished by routing the audio
from the receiver audio output to the audio (MIC or Line
In) input of the sound port of the computer. The
software runs on Windows 10, Windows 8.1/8.0, Windows 7,
and Windows Vista operating systems. The program is
optimized for keyboard to keyboard operation.
