[CQ-Contest] New program to analyze passes in a Cabrillo log

I wrote a short program which attempts to locate passed QSOs in a Cabrillo 
log.  You can download it from:


The program will only run in a DOS window on Win 95/98/NT/2K/XP, it will 
not work in ordinary DOS. I'll see what I can do this weekend about fixing it.

The syntax is:

         pass <CONTEST.LOG> [minutes]

The log must be in Cabrillo format, or the program will exit.  The output 
will be written to a file of the same name as the input, except with a 
".PASS" extension.  You can open this file in notepad to view it.

Minutes is the pass "window", default is 5 minutes if not specified.  If 
the same station isn't logged within that time window on two different 
bands or modes, it's not considered a pass.  Each pass starts a new window, 
so it's possible to see passes to three or more bands grouped together, if 
the time between each QSO is less than the window size.

Here is a sample of the output from one of KC1XX's old logs:

>Reading QSO data from kc1xx.log
>         7716 QSOs.
>         3659 unique callsigns.
>         Pass limit = 5 minutes.

I hope people find this useful.  I have tested it with only CQWW and ARRL 
DX, but other contests *should* work.  I'd be happy to hear your comments.
