This window is the main window of NuMorse.  To close this window select File|Exit or mouse click the 'X' at top right of the window. Closing this window will also exit from the NuMorse program.

 

Here are the main items in this window:

 

The digital clock display which also doubles as a count down timer if the code session is set to stop after a predetermined time.

 

The code source selector.

This drop-down list control allows you to select how the Morse code is generated. Here are the list options:

 

Send random characters in groups.

An internal random character generator sends text. The group length can be adjusted in the program options section while the characters sent are determined by the Filters section.

 

Make QSOs or callsigns.

Typical conversations that might be heard on the ham radio bands are generated and sent as Morse code. The length and content can be adjusted in the program settings section.

 

Play text from code source window.

Whatever text is in the code source window is played as Morse code. The text may have been typed in, or loaded from a file or remaining from a previous code session.

 

Random words from code source window.

This is similar to the previous item except that each time a space is encountered a different part of the text is selected.

 

From keyboard.

Whatever is typed into the keyboard is sounded as Morse code.

 

 

The digital clock display doubles up as a "time remaining" display if you have limited the code session time .

 

The Start button begins to play Morse code from whatever source you selected.

 

If the Drill box is checked then NuMorse will wait for your typing after each word of code was sent. After you have typed in the characters that you think were sent press the space bar. NuMorse will then respond in various ways depending on the drill settings you have chosen.

 

If the Drill box is not checked then code will be sent continuously until the Pause or Stop button is pressed.  NuMorse will continue to monitor anything you type and record statistics , but it will not wait for you.

 

The Pause button temporarily suspends code play. Press start to continue from the previous code source position if reading text..

 

The Stop button ceases code play. The code source position is reset next time you press play.

 

Just below the Code Source selector is a window that shows the last few characters sent. Below this is another window.which shows the dit-dah pattern of the current character.

If you are trying to learn the code then you will not want to see what characters are being sent. Small check boxes next to the appropriate windows (shown above) allow display of sent characters to be suppressed.

 

The lower part of the Main program window contains items related to code speed. The two sliders work as follows:

 

The top code slider controls how fast each code character is sent. The speed can be set from 2 to 49 W.P.M. (Words per minute).

 

The bottom text slider controls extra spaces between the code characters. If this is set to the right hand position then no extra spaces are added and the code sent is standard Morse code. Adding extra spaces makes the code easier to read for beginners. This slows down the overall sending speed and the effective speed is shown in green. Code with extra character spaces is sometimes called Farnsworth code. F.C.C. code tests in the U.S. are taken with a character speed of 18 WPM but with extra spaces inserted to reduce the overall speed to 5 WPM.

 

There are two buttons next to the speed sliders that are used to recall preset stored speeds .
