CwType 2.1

CwType is the terminal program for CW-operators. You can transmit both from the keyboard and from a paddle connected to game or LPT ports. You can also operate in paddle iambic mode. Control of the transceiver (PTT and CW keying) is made through one of the COM or LPT ports. CwType can integrate with AALog software.
The "TX" button switches the transmitter on. The program transmits chars entered into the bottom window. During transmission, chars move from that window into the Sent Symbols window (upper window). Chars sent by paddle are shown in upper window also.
There is a sound on/off button in the top right hand corner. Sound can be produced from the internal computer speaker or a sound cord. Sound source is selected in the "Setup/Sound" page.
Sound frequency is defined at the same page. A soundcard generated signal has a sine waveform and a smooth envelope, so it can be used to form a CW signal from a SSB transmitter. The rise and decay time of soundcard generated CW-signals is defined by "Rise/Decay time". It is the time for a signal to rise from a 0 to 100% level in milliseconds. A rise time from 10% to 90% level is about 0.6 of a value defined by this control.
