Sergei Podstrigailo, UA9OSV http://www.dxsoft.com, the writer of TrueTTY has produced a fine complementary pair of programs for keyboarding CW. These are actually two separate programs: CwGet, which is used for receiving Morse code, and CwType for sending code via the keyboard. These programs are written in windows, can be opened together on the main screen, and the layout is easy to understand and easy to operate. 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. The spectrum display is about 2,500Hz wide and since the software uses the Computer soundcard, the bandwidth of the receiver is not important. The filter algorithm used by Sergei is excellent and self centers automatically on the frequency of the incoming signal. The screen shot below shows both the CwGet and CwType main screens arranged together.

The software, cwget110.zip can be downloaded directly from this site and comes zipped. Simply download the file into your CwGet folder and unzip it and run setup. I recommend putting a 'shortcut' CwGet Icon on your desktop.
CwGet uses the computer sound card and only requires connecting the radio external speaker jack into the sound card. No other interface is required. The sound card should be at least 16 bit. The recording level is varied by adjusting the Volume Control on the computer. Make sure that the input signal does not overload the sound card input as this will certainly degrade the operation. Sound card interfacing has been discussed at great length on this web site. 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.
The main screen is divided into 3 window, the sizes of which can be adjusted by dragging the borders. The top window displays the current spectrum of the signal shown in blue, and the spectral components shown in green. The vertical red line shows the center frequency of the filter. 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 AFC button, Auto Frequency Control, works in conjunction with the small number box to the left of the AFC control. This acts as the AFC bandpass, and each step is approximately 5Hz.
The GotoMax button forces the red line,(working frequency) to jump to the closest peak displayed on the Spectrum Display. The AutoGTM button switches on the automatic mode of GotoMax. This will make GotoMax jump to the strongest peak displayed after detecting a pause of more than eight 'dots' in the current signal.
The OnTop button forces CwGet in front of all windows.
The bottom window is an oscillogram of the signal. A red horizontal line shows the threshold level which can be adjusted by dragging with the mouse or by selecting Auto Threshold.
The receive symbols are displayed in the center window. Periodically a dash-dot sequence in curly brackets will be observed. This means that the decoded signal is unidentified. The background color, font color and face can be user adjusted by changing the values of Rx Window Background Setup or Rx Windows Font Setup found in the Setup menu. Since the window has scroll bars, no text is lost.
The number shown in the FrB field on the status bar shows the number of free buffers available for recording. If it is reduced to ten or less the speed of the computer will not keep up. Try reducing the number of simultaneously running programs or replace the computer :-)

CwType is Sergei's Keyboard code sender. Both CwType and CwGet can be run simultaneously. Download the software, cwtyp104.zip from this site and unzip it in your CwType folder. I recommend you put a shortcut, CwGet icon on your desktop.
Now, CwType does not use the soundcard. A very simple circuit that uses the Com Port DTR line is shown below. Also shown is a circuit for using the  RTS  line if you prefer, but convention normally uses the DTR for sending CW and the RTS for switching the PTT.  There is more Radio to Computer interfacing help on the Hook-up page. Try this if you need more information.
Now! for you Collins owners, Joe, w0tut has kindly submitted the following  schematic drawing and design comments. Thanks Joe for your valuable input.
At this point I think you should print off the different sections of both the CwGet and CwType help files. These are located on the top Menu Bar on each of the front windows. There is not a lot of printing and the information is valuable. It would be worth keeping them in a hard copy file. Please take the time now to read through both these documents thoroughly. You will find configuration file instructions in detail and what to modify to achieve the required results. The actual configuration file, CWTYPE.ini is found in  the same directory as the CwType.exe file, and must be edited to conform to your system and personal needs. As an example, if you want to set the Active Com Port for the Keyer: open CWTYPE.ini with your favorite editor and change the instruction "KeyPortNumber" to the com port you require. It is that simple. However, click on this Configuration Pop-up. to give you a somewhat better understanding of logic behind the Com Port configuration, 
Now the schematics shown below might need some explanation. There are two circuits shown. One, which uses the RST line of the active com. port to send Morse Code, and the other using the DTR line. Select either one, but not both unless you plan to use this interface for other sound card modes as well as CW.  Now make sure that you tell the CwType.ini file what you are using here. For example, my interface will use the  DTR control circuits, and I  will NOT be using the MOX (VOX) option. So I need to activate the DTR line. To achieve this, I set the KeyOffTxOffByte=00, KeyOnTxOffByte=00, KeyOffTxOnByte=00 and KeyOnTxOnByte=02. If I decided to send code via the RTS line I would change the instruction KeyOnTxOnByte to 03

Don't forget that the CwGet software uses the computer sound card instead of a TNC and CwType a simple transistor circuit to key the radio. To achieve this you will need to interface the Radio to the Computer. This is quite easy. On the CwGet and CwType help files you will find the relevant schematics. Alternately I have schematics showing numerous interfacing and PTT switching options with a detailed discussion on the setup. These can be found on my Interfacing web page.
Now, to get you up and running and on the air fast, I recommend the following:

• Download and unzip the files cwget110.zip and cwtyp104.zip.
• Interface your Radio to the Computer. See above for the details.
• Click on the CwGet and CwType icons on the desktop and adjust the 'main screen' to the size you want.
• Go into the CWTYPE.ini file with your favorite editor and make sure that your active com port is selected by the Instruction, KeyPortNumber, and the KeyPortType=2.
• In the CwType program you should now write your Buffers in the drop down menu "Edit Macros" in the "Setup" menu. This will make it easier in a rag chew to queue some common exchanges such as CQ, your name, QTH and the shack information.
• Switch on the rig and look for a CW signal. You should see one or two signals on the CwGet Spectrum Display. Tune your rig and move the peak towards the Red line. If you have the AFC enabled you will observe the peak jumping towards the Red line, and locking on. At this time there should be print on the Screen. The bottom task bar will show the filter, frequency, and speed information of the incoming signal. If the signal is a CQ, throw your call out a few times by either typing directly into the Input window then clicking Tx or click F1 and send out your prewritten CQ macro. Either way your rig will fire up and you will be ON THE AIR!
