About ADIF Prefix Calculator

This software loads WPX type ADIF files with the <PFX:xxx> tag and calculates the different callsign prefixes. The software will load and capture the totals for big files. ADIF files must have the .adi file extension.

The output is a matrix of unique prefixes:
Total unique prefixes overall.
Total unique prefixes by band and mode 160m thru 10m, including the WARC bands.
Total unique prefixes per mode PH, CW and DIG.

PH = PH, SSB, AM and FM
All other modes are considered as DIG.

The default folder when you extract the software is c:\ADIF_PrefixTotals. You may put the software anywhere. Put the ADIF files in the default folder or optional folder. See `Optional folders for files` below.

Click an ADIF file, then click Calculate. The results are printed to the screen. Use the Print Screen menu to print the screen capture. The same information is also written to the {ADIF_filename.sum} text file. "ADIF_filename" is the name of the file being calculated (W3KM.ADI, 2011 CQ WPX RTTY.ADI etc.) - the .ADI extension is replaced with the .SUM extension.

The software screen can be re-sized by dragging the lower-right corner of the form. Use the upper-right-X to save the position and screen size.

To view or edit the ADIF file, click the file and do right-mouse click. NotePad or EditPad must be in the application folder for this open function to work.

To view the SUM file, do right-mouse click on the summary output window.

Help files:
In the Help menu, select to use either the older WinHelp32 file or the HTML (.chm) file. Click Contents to view the help. Or you can open the flat HTML file or the other Help files in MyComputer.

Optional folders for files:
You can use 2 optional folders for the .adi and .sum files. Making the folders under the application startup folder will be the easiest to set and to find. You must make the 2 new folders first. Then put the ADIF files in the ADIF folder.

Use the File Set folders menu.
The `Default` folder is the application startup folder.
Make new folders, for example:
