Shortwave Listeners Logging Program

Introduction
ÄÄÄÄÄÄÄÄÄÄÄÄ

   After downloading many SWL logging programs from CompuServe and other BBS's
I decided to create a simple SWL logging program that fit my novice needs as I
spun the dial of my DX440 shortwave receiver late into the night and early 
morning.  Being a CLIPPER programmer by trade, I decided to create the program
using CLIPPER Summer 87 version, single user, without overlays, and of
relatively small size.

   The program uses dBASE III type databases, and CLIPPER index files (.NTX).
I tried to incorporate features from sample log book examples which I found
useful when choosing database fields, coupled with my brief DX'ing
experience.  The following fields were selected:

   Date      - date of logged reception
   Time      - time of logged reception
   Station   - ID of station
   Location  - geographical location of station
   Frequency - received frequency in kHz
   Band      - band in meters
   Power     - transmitting power of station
   SINPO     - receptivity codes
   Program   - name of program being transmitted
   Language  - reception language
   Comments  - a note about the DX


   The arrow keys on the keyboard move through menu selections, and [ESC] in
most cases returns the user to the previous menu or operation.  Menu options
are shown on the bottom of the screen and are selectable when the program is
in a 'wait state'.  When the seconds are ticking on the screen, the user is
in a wait state and may select a menu option.


Installation
ÄÄÄÄÄÄÄÄÄÄÄÄ

   Copy the SWL1.EXE file to a directory and decompress the file by typing:
                               SWL1 <return>
    
   To execute the program, type: SWL_LOG <return>
 
Selecting A File
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
   
   New loggings are placed into one of three files; a master file, an existing
file, or a new file.  A master file, SWL.DBF, is provided from which new files
are created.  If you keep log data in the master file, and later choose to  
create a new file, only the master file structure will be copied into the new
file.  Master file log data remains in the master file.  A user, for example,
may wish to create a separate log file each month to compare DX'ing activity
by month.  Each new file would contain the file structure of the master file.
A user may not use a filename of an existing file when adding a new file.
Choosing an existing file allows a user to continue appending new loggings to
existing data.


Choosing A Time Zone
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

   Since UTC is displayed, a user must select his/her proper time zone.  Use
the arrow keys to move to a time zone and press the Enter key to select the
time zone.  Each time zone description is shown at the bottom of the screen as
time zones are highlighted.  After a time zone is chosen, the main screen is
displayed.


Using The Program
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

   a. Adding New Station Data - [F8]

        A separate data entry screen containing the fields
        specified above is displayed.

   b. Editing Existing Station Data - [<ÄÙ]

        Use the arrow keys to move the cursor to the item to be 
        modified, and press the Enter key.  Arrow keys allow 
        movement vertically through the fields of data.  Any
        field of data may be changed.

   c. Deleting Existing Station Data - [Del]

        The delete key [Del] deletes a logged entry.  If the
        delete key is pressed on an already deleted item, the
        item is recalled or undeleted.  Deleted items are
        purged from the file when entering the program only.
        During a logging session, items may be deleted and 
        recalled, however, after a file is closed and reopened
        deletions are purged from the file.

   d. Leaving The Program - [ESC]

        Pressing the [ESC] key from the main screen will exit
        the logging program.
        
   e. Reports - [F2]

        Both screen and printer output options are available.
        Each report presents the logged data in a different
        sorted order.  The following reports may be chosen.

        Date - Entry Date Report
        Station - Station ID Report
        Frequency - Frequencies in ascending order Report
        Time - Logged Time Report (standard time)
        Band - Band plus Time Report
        SINPO - Sorted from best to worst reception value.
        Location - Sorted by country location, i.e., Germany, Cologne.
