NuMorse Professional, Morse code practice software. Frequently asked questions.

Q. NuMorse Professional will not even start up! Why?

A. There are two common causes. The most likely is that Data Execution Prevention (DEP) is set to block all programs except ones you specify. DEP was introduced in XP service pack 2 and has been present in all subsequent Windows versions. Here are some links to instructions on how to run NuMorse Professional if it is blocked by DEP:

Microsoft FAQ page

Another possibility is that another program is preventing NuMorse Professional from starting up.
Update: As from build this is no longer a problem. A vulnerability was discovered in previous versions  that allowed certain programs to 'block' some Nu-Ware products as they were starting up. This was not deliberate but was due to sloppy programming by the developers of the 'blocking' programs.

Q. I get a 'Couldn't generate a valid QSO string' when I try to play QSOs

A. The QSO generator scripts use the characters required for FCC code tests. These are:

The upper case letters A..Z (Code uses uppercase only)

The numbers 0..9

The period, the comma, the question mark.

The prosigns AR SK BT DN

The list at the left side of the QSO options page specifies what characters are to be included in a QSO. If the specified characters are not available in the generator script then the above error message will result. For example, if the list includes letters 'abc' then the  QSO generator will fail. The solution  is to remove all characters from this list that are not used in the test.

The list was included in the program in case people wanted to modify the generator scripts to use non-standard characters. Details are in the help file.

Q. I want to use my own text files with my NuMorse Pro Morse code practice software. How do I do this? My files are being ignored.

A. Reading from text files is a major function of NuMorse Pro Morse code practice software. For starters, the file does not need to be in NPDDefault, this is where program settings are stored and so are code source files by default but they can be anywhere on your system. There are a few reasons why your file might be ignored... Go to Input and Output\Select Input device (or press shift+F4) and make sure that the input device is set to Text File. Go to View\Code source (or press F2) and check that your text file appears in the code source window. BTW, you can leave this window open while playing code. This applies to most NuMorse Pro windows. Another suggestion...go to View\File Window options (press Ctrl+Shift+F2) and make sure that the 'Don't save' checkbox is checked in the 'Code source file, save on...' group is checked.

Q. How do I know if my license code was accepted?

A. To check that the code installed correctly go to Help\About and you should see your name displayed.

Q. I want to use the following none US characters [, and ] but when I add them they are ignored.

A.The problem may be due to the character filter feature. This is handy for limiting characters to the ones you want to learn but it can also remove wanted characters. Go to Play\Character Filter (or press Ctrl+F9 keys). At top left of the filter window is the preset filter group which will probably be set to the American FCC setting which excludes , and .. Set this to "Allow all".

Q. After I have been using NuMorse Professional Morse code practice software for a while the sound cuts off. I have to restart the program to get sound again. Why is this?

A. This only occurs in the unlicensed version and is a gentle reminder that you haven't yet paid for the program. The licensed version does not time out.

Q. The "Play Morse Code" option does not work

A. This may be because you have another code play window open, such as the First Steps window. There are several places in the program where code gets output. To avoid the situation of the program trying to simultaneously play *two* different streams of code only one code play window can be open. Try closing the First Steps window and the code play window will probably work OK. Other windows which are mutually exclusive are the "Calibration" and "Set a test" windows.

Q. The "First Steps for Beginners" window won't open.

A. See the answer to the next question.

Q. Some menu items are grayed out (disabled) and so I can't access certain program features. What is going on?

A. Certain of the Morse code practice software features are mutually exclusive. For example, the First Steps for beginners feature cannot be used at the same time as the Play Morse code feature. To open it you need to close the Play Morse code form.

Q. I miss the immediate letter by letter corrections which NuMorse used to have.

A. It is still there but amongst other Drill options. Here is how to set it up so that it works like the older version:
a) Go to Drill Settings (or press keys shift+F6)
b) The following should be checked:
Every character sent
Enable smart spaces
Wait for user to catch up
Play sound name
Show error (if you want to see what mistake you made)
Restart drilling after 1 second
All other options unchecked.
Now click on Drill and the program will send a single character and then wait for your input. It will also display a window (User keypresses) where your typing is displayed, you can reposition or minimise this window. If you type an incorrect character then an error window is displayed. The error window has an auto close feature so that you can type responses without interruption.

Q. I installed the keycode that you sent but the program still starts up as the unlicensed version. I also saw an error message during the keycode install. What has gone wrong?

A. Did you purchase a NuMorse Pro license? The keycode systems for NuMorse Standard and NuMorse Pro Morse code practice software are not interchangeable.

Q. I get a floating point error message when the program starts up but then everything appears to work OK. Suggestions?

A. Some early versions of NuMorse pro were shipped with a corrupt file. The file is LogFile.dat. To cure the problem go to View\Performance (or press Ctrl+P) and click on the clear logfile button. This is at top right of the performance form.

Q. I have selected QSO\File\Callsigns but the code output is all jumbled up and random. How do I cure this?

A. You probably have the Source randomize feature switched on. Go to View\File Window options (or press Shift+Ctrl+F2) and check the Sequential read option.

Q. There seem to be some missing characters in the code output. I need the [SK] prosign symbol and NuMorse Pro refuses to play it.

A. Check that the current filter allows this symbol. The filters form is accessed from Play\Character Filters (or Ctrl+F9). In the US most people will find the F.C.C. filter most useful. Try the Allow all setting. If you cannot find a combination of filters that fits your needs then set up a custom filter.

Q. Some of the words in QSOs appear to be joined up as if a word space is missing. Eg. WX SNOWINGICY. How can I fix this?

A. You have probably filtered out punctuation, see above answer and turn on the F.C.C. filter.

Q. I'm getting all sorts of strange nonsense characters played as code. What gives?

A. You may have the "Allow all" character filter selected. Normally you would select one of the other filters. In the U.S. the F.C.C. filter is probably the most useful.

Q. I'm in Norway and need to use the "dah-dah-dah-dit" character in my Morse code practice software. Can NuMorse Pro do this?

A. Yes. You have two options.

1) The simplest method is to customize an existing character that is not used in Norway. All of the lower case keyboard characters are available for customization via the Code Properties form. Using this method, the original character symbol cannot be changed, just the code sound.

2) There is also an advanced feature called character mapping that allows you to completely reassign a keyboard character, including the character symbol. In NuMorse Pro all of the characters above ANSII code 128 are available for mapping. The special NuMorse font includes many extra prosigns and other useful symbols. The help topic explains the mapping feature in more detail.

Q. I'm in a mess with my Morse code practice software! I did some experimenting and have changed so many settings that the program no longer works at all. Help!

A. Select Help\Restore settings. This should get NuMorse Pro back to the settings when you installed it. Only the current profile is affected by this feature.

Q. I'm hearing clicks and thumps in the sound output.

A. There are many possible reasons for this problem which only occurs on a small percentage of systems. Other users have found the following suggestions sometimes help to find the problem.

In NuMorse Pro go to Settings\General preferences (or press F6). Experiment with the Advanced sound board options. There may be combinations of settings that crash the program but other combinations may fix the audio problem.

Close down as many other programs as possible. In a multi-threading system such as Windows other processes can periodically access the sound card and cause clicks even though that software is not specifically designed to produce sounds.

Consult your system documentation to find out how to check for and resolve possible IRQ conflicts between the Sound Board card and other system devices.

Do you have the most up-to-date Sound Board drivers? If you have an internet connection available, consult the Sound Board manufacturers web site, and look for the latest version driver. You can also check with your computer supplier for the latest driver.

Have you tried the built-in Windows Trouble Shooter? If not, here is how you do that.

Windows 95 Users: There is no specific troubleshooter for sounds. Click Help in the Windows Start menu. When the Help window opens, select the index tab and enter "sound". Now select a topic from the list.

Windows 98 and ME Users: Click Help in the Windows Start menu. When the Help window opens, pick Troubleshooting in the Contents Tab. Next choose Windows 98 or ME Troubleshooters, and select Sound when this entry expands. Then follow the on-screen instructions.

Windows 2000 Users: Click Help in the Windows Start menu, when the Help window opens, click Troubleshooting and Maintenance on the Contents Tab, then click the Windows 2000 troubleshooters entry. Finally select the blue sound link that appears in the right hand pane, and follow the on-screen instructions.

Video drivers are often a major source of apparently unrelated problems. Video card manufacturers are constantly revising drivers, check the manufacturer's web site to see if a new driver release is available. The Creative SoundBlaster newsgroups have had some postings concerning a crackling noise problem in the past.

You can search archived newsgroup articles by going to this site: When prompted for search keywords enter the three words "sound card problem" and you will get back pages and pages of links that refer to these words. You can then refine your search words to find something that might relate to your particular situation.

NuMorse Pro works by sending a series of short sound samples to the Sound card and so the output quality relies on the sound card hardware/software stitching these samples together seamlessly.

Most sound cards do this fine but a few cards miss the first few milliseconds of each sample. This can give rise to clicking at the start of each code character. This effect is most noticeable when the "Real Morse code" feature is sending noise. You may hear regular breaks in the noise if your system is struggling to correctly join the individual samples. There are some advanced sound card settings in Settings\General Preferences that might help. Experiment with these settings, but make a note of the default settings before you begin!

Q. I'm having trouble setting the speed with the slider control. It seems too coarse and I can't get exactly 20.0 WPM.

A. After setting the speed approximately using the mouse you can use the keyboard up/down arrow keys for fine control.

Q. I've noticed some inaccuracies in the generated callsigns. Some of them would never be issued by the FCC. Why is this? In any case, I am from Italy and would prefer European callsigns for practice.

A. Well spotted! I have set up the callsign generator to use the U.S. FCC rules as I understand them. As a UK license holder these rules seem rather complex to me and I may have made a few errors. The callsign generator is customizable so you are free to change the rules, or even completely replace them.

For a comprehensive tutorial on customising the callsign generator click here. This manual is in Adobe Portable Document Format (PDF) format. If you do not have a copy of the free Adobe Acrobat Reader then it can be obtained from the Adobe website.

Q. The QSOs are all U.S. based. How about a version for us in the UK?

A. If I had time I could do a version for every region! The QSO generator rules can be altered to cater for any location and could even be rewritten for other languages. The files Topics.txt and Phrases.txt contain data for the QSO generator and some hints for changing them are given in the help topics.

Q. What does NuMorse Pro do if I uncheck the "Always ask when file changed." box in the form that sometimes appears when exiting?

A. With this box unchecked NuMorse Pro will always silently write any changes out to the selected code source file.

Q. In the "First Steps" options there is a warning that "Global changes cannot be undone". What does this mean? I seem to be able to reverse changes just fine.

A. It means that there is no simple "Undo" button. You can, of course, undo changes by selecting appropriate options and doing a second global change to get back to your starting point.

Q. I can't run NuMorse Pro Morse code practice software at all. I'm running Windows 2000.

A. There seems to be an issue with V1.1 and Norton Anti-Virus on some machines. Please download and install a later version.
