         INTRODUCTION

         CWT 11.3 is a FREEWARE program. That is, you may copy, distri-
         bute and use it without any restrictions but these:

         1. You are not allowed to charge any amount of money for it.

         2. All copied files must be handled over in their original form
            and content.

         3. You are not allowed to use CWT 11.3 in a business, commercial,
            government, or institutional environment except for evaluation
            purposes.

         All texts and graphics of CWT 11.3 are carried out in German,
         support for English or other languages has not been provided.
         Nevertheless you will find the program comparatively easy to
         handle even though you may not speak any German at all. And
         CWT 11.3 offers some special functions not commonly found in
         comparable freeware or shareware programs. Thus it still may
         serve you well to some extend.

         The following gives you a brief overview of all files included
         in the original distribution file. Those absolutely mandatory
         for running the program are marked by the letter '*'.

         WHAT CWT 11.3 HAS TO OFFER

         CWT 11.3 is a morse code trainer for radio amateurs providing the
         following futures:

         - a clearly structured, neither cluttered nor primitive graphic
           user interface closely kept to SAA standards which makes the
           program pleasant and easy to use

         - a code generator capable of sending random groups of equal or
           different length, common (German) words, abbreviations for CW
           work, amateur text (automatically generated) and external text
           files

         - an integrated editor for creating the latter mentioned text
           files

         - a decoder which reads code characters from an externally con-
           nected morse keyer and converts them into readable text (morse
           keyer connected to the parallel port)

         - a bar writer which reads code characters from an externally
           connected morse keyer and converts them into graphic bars

         - a possibility of saving all important configuration parameters
           for later use

         - support of SOUNDBLASTER compatible cards including several sound
           effects like QRM, QRN, QSB and QSD



         EQUIPMENT AND SYSTEM REQUIREMENTS

         - an IBM compatible PC equipped with a 286 series processor or
           higher

         - 450 kB free memory

         - approximately 950 kB free disc

         - a VGA video adapter

         - a parallel port for connecting a morse keyer

         - optionally a sound card (SOUNDBLASTER compatible)

         - MS-DOS, PC-DOS oder DR-DOS (version 3.0 or higher)



         HOW TO INSTALL CWT 11.3

         First copy all files into a common directory of your choice. If
         you do not take further measurements you MUST then start the pro-
         gram from within this directory. Otherwise CWT 11.3 will not be able
         to find its files. Alternatively (and certainly more comfortable)
         you may include the following instructions in your AUTOEXEC.BAT:

                            Ŀ
                              SET CWT=[[drive:]\path]  
                                                       
                              PATH [[drive:]\path]     
                            

         Assuming you have copied the files into a directory called CWT
         on drive C:. In this case you must include:

                                Ŀ
                                  SET CWT=C:\CWT  
                                                  
                                  PATH C:\CWT     
                                

          If a PATH instruction already exists in your AUTOEXEC.BAT and
          assuming the complete instruction to read like this:

                           Ŀ
                             PATH C:\MYTEXT;C:\MYTOOLS  
                           

          Then the new instruction should read as follows:

                      Ŀ
                        PATH C:\CWT;C:\MYTEXT;C:\C:\MYTOOLS   
                      

          Next reset your computer once. After this has been done you may
          start CWT 11.3 from within any directory whatsoever by just typing
          [CWT] at the DOS command line and pressing <RETURN>.

          As CWT 11.3 uses one of the system timers which function is al-
          tered by software you should not try to run the program under
          WINDOWS. But instead you may try run CWT 11.3 from an OS-2 com-
          patibility box. The author has not been able to carry out a suf-
          ficient series of tests because no OS-2 is installed on his com-
          puter, but several users have frequently reported that it works.
          Just be aware of the fact please that some functions of CWT 11.3
          are a bit critical regarding time consumption. For this reason
          you should avoid multitasking operation while running CWT 11.3
          unless your computer is sufficiently fast.



          USING A SOUND CARD

          SOUNDBLASTER compatible sound cards are supported. The default
          setting forces CWT 11.3 into using the PC speaker as sound out-
          put device. Thus you first must alter the setting if you have
          a sound card installed and want to use it. This can easily be
          mananged from within the program. Simply open the pull-down me-
          nu named Einstellen by pressing <Alt>-<E>. Then move the cur-
          sor to the row called Blaster and press <RETURN>. Please note
          that CWT 11.3 automatically checks for a SOUNDBLASTER compatible
          card. If none is detected the Blaster row in the above men-
          tioned pull-down menu remains locked. Therefore make sure that
          your sound card is set up properly for SOUNDBLASTER compatibi-
          lity before starting the program. In case of troubles consult
          the manufacturer's manual.



          HOW TO CONNECT A MORSE KEYER

          For this purpose your computer must be equipped with a paral-
          lel port. For connecting a keyer get a suitable 25-pole plug
          and carry out the following job:

          The morse keyer must be connected to the parallel port by means
          of a one-pole SHIELDED cable. Solder the cable's inner conductor
          to PIN 10 and the shielding braid directly onto the plug's metal
          flange. Both serve as the keyer's lead lines. The following dia-
          gram illustrates the correct connections seen from the plug's
          back.
                             14                    25
                            __________________________
                           / o o o o o o o o o o o o  \
                          / o o o o o o o o o o o o o  \
                         xĳ
                            1                     13
                                             
                                             >  to keyer
                                           >

          In case your computer provides more than one parallel port you
          should choose LPT 1 for connecting the keyer, because by default
          CWT 11.3 assumes the keyer to be connected right there. But if
          desired you may select another port from the menu Einstellen.

          Please note that there must be NO voltage on the keyer's lead
          line. Therefore only mechanical hand keyers or elbugs with in-
          built, separating relays at their output ports should be used.
          Otherwise some sort of protective hardware interface would be-
          come unavoidable to prevent the port from suffering severe da-
          mage.



          SOME BASIC HINTS

          Whenever you start running the program, the generator's window
          will first appear on the screen. In order to start the character
          generation simply press <Space> (called Leertaste in German).

          All important parameters for keying, group generation, character
          set and sound can, of course, be altered. This can either be done
          by opening the above mentioned pull-down menu Einstellen or by
          just pressing the following function keys:

                     Ŀ
                       <F5> set keying parameters            
                                                             
                       <F6> set group generation parameters  
                                                             
                       <F7> alter character set              
                                                             
                       <F8> set sound parameters             
                     

          The <F4> function key is provided for toggling between genera-
          tor and decoder. The bar writer (called Morseschreiber in Ger-
          man) can be activated by pressing <F10>. All those other func-
          tions which have not been mentioned here can be figured out
          easily while running the program.

          Of course I am aware that this text is by far too scarcely kept
          to be called a documentation at all. The same by the way is true
          for the German text version simply due to the fact, that all op-
          erating instructions can be obtained from an extensive online
          help system. You may probably not be able to benefit at all from
          the latter but please consider, that CWT 11.3 in its present ap-
          pearance has chiefly been developed to serve the needs of German
          radio amateurs only. And after all, writing any reasonable manual
          or online help in English would certainly be far beyond my capabi-
          lities.
