The " Weighting " value is used to eliminate morse elements clipping by some transmitters with QSK. The " Paddle in Iambic mode " option switch on the "Iambic" mode the memory of a unit of a symbol for paddle handling. When the " Pause Off at Tx Off " option is checked, the "Pause" mode is switched off after the transmitter is off. When the " Pause On at paddle press " option is checked, pressing a paddle switches on the "Pause" mode. The " Real output sampling rate " value means the real sampling frequency of a sound card. Sound frequency is defined at the same page.Ī 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. Sound can be produced from the internal computer speaker or a sound cord.

Hotkeys for speed adjustments are Alt- keypad plus or Ctrl- keypad-plus and Alt- keypad minus or Ctrl- keypad minus. Transmitter is left on and you can send symbols via paddle. The " Pause " button stops sending pre-typed symbols. During transmission, chars move from that window into the Sent Symbols window upper window.Ĭhars sent by paddle are shown in upper window also. The program transmits chars entered into the bottom window. The " TX " button switches the transmitter on. Try reducing the number of simultaneously running programs or replace the computer Both CwType and CwGet can be run simultaneously.ĭownload the software, cwtyp I recommend you put a shortcut, CwType icon on your desktop.CwType can integrate with AALog software. If it is reduced to ten or less the speed of the computer will not keep up.

T he number shown in the FrB field on the status bar shows the number of free buffers available for recording. Since the window has scroll bars, no text is lost. This means that the decoded signal is unidentified. Periodically a dash-dot sequence in curly brackets will be observed. T he receive symbols are displayed in the center window. A red horizontal line shows the threshold level which can be adjusted by dragging with the mouse or by selecting Auto Threshold. T he bottom window is an oscillogram of the signal. T he OnTop button forces CwGet in front of all windows. This will make GotoMax jump to the strongest peak displayed after detecting a pause of more than eight 'dots' in the current signal. T he GotoMax button forces the red line, working frequency to jump to the closest peak displayed on the Spectrum Display. This acts as the AFC bandpassand each step is approximately 5Hz. To change the center frequency, simply click on the frequency axis, drag the red line or click the spectrum peak you want to receive. The vertical red line shows the center frequency of the filter. The top window displays the current spectrum of the signal shown in blueand the spectral components shown in green. T he main screen is divided into 3 window, the sizes of which can be adjusted by dragging the borders. For isolating the radio and computer or making the interface compatible with the various sound card modes now available please check out the Hook-up page. Sound card interfacing has been discussed at great length on this web site. Make sure that the input signal does not overload the sound card input as this will certainly degrade the operation. The recording level is varied by adjusting the Volume Control on the computer. The sound card should be at least 16 bit. C wGet uses the computer sound card and only requires connecting the radio external speaker jack into the sound card. I recommend putting a 'shortcut' CwGet Icon on your desktop.

CwGet T he softwarecwget Simply download the file into your CwGet folder and unzip it and run setup. The screen shot below shows both the CwGet and CwType main screens arranged together. The filter algorithm used by Sergei is excellent and self centers automatically on the frequency of the incoming signal.

The spectrum display is about 2,Hz wide and since the software uses the Computer soundcardthe bandwidth of the receiver is not important. As well as the familiar type-ahead buffers, Sergei has included a Spectrum Display window which is used to tune the CW stations into the filter bandpass which you set in the software. These programs are written in window s, can be opened together on the main screen, and the layout is easy to understand and easy to operate.

These are actually two separate programs: CwGetwhich is used for receiving Morse code, and CwType for sending code via the keyboard.
