The K4HAV 10-10 Contest Program was recently used
by the author (K4HAV) in the Summer 1990 10-10 QSO
Party Contest. After working 805 stations during the
contest, the log and dupe sheet was printed in less than
five minutes. The program is similar to the CT and NA
contest programs used by the author and other contesters
as described in an article in the July 1990 QST, pages 14-
17. It uses many of the same keystrokes, but has features
needed by 10-10ers. Some of the features are:

1. Capacity for 2500 QSO's with all information in
memory for instant access. Each QSO is written to disk as
logged. 

2. Stations worked in the first contest are converted to a
database which is available for the second and later
contests. If a station has been worked in an earlier contest
then his info is displayed on the log screen for correction
and/or confirmation. This will save much typing and the
other station will be amazed at your memory when you
say "Thanks Bob for the call - nice to work you again."
As more contests are worked your database will grow as
the new stations worked will be added to the existing
database. There is a function key (F3) to defeat the
database checking procedure if desired. Depending on the
computer memory the database capacity can exceed ten
13000thousand calls with info.

3. Provisions for partial call checking against database and
current log. For example: if you hear a station signing
"Alpha Victor" - entering "AV" for the call and hitting F8
or F9 will give a list of calls or calls w/info on a pop-up
screen. You will probably see the call K4HAV on the
screen.

4. If only a 10-10 number is heard then F7 gives a pop-up
window for checking to see if the station has been worked
or can be identified from the database.

5. Choice of on-line editing for last 9 QSO's or full log
editing from a window displaying 46 QSO's per screen.

6. A complimentary copy of the K4HAV condensed version of
WA6POZ's database of all 10-10 numbers - callsigns and silent 
key indicators is included along with K4HAV's version of a 
SEARCH program that loads all info into memory and is 
extremely fast and compact.

7. Many other features including on-screen help - on-line 
duping - automatic DX country recognition - display for requested 
DX prefix or country - display of states needed for 'CONTEST WAS'. 
The update current score - operating time - overall contest rate - 
last 10 QSO rate and last 100 QSO rate are displayed after each 
QSO is logged. Documentatin printed on a laser printer as well 
as detailed help screens.

8. Written in MicroSoft Quick-Basic (assembly used for all
search/sort routines) by James D. Hardy - K4HAV - owner
of Hardy Data Systems - developer and distributor of
software for AM/FM radio stations and the florist
industry. 

9. Printer support for IBM/Epson compatible printers and
the HP Laser Series II printer. Dot matrix printer codes
can be user modified.

10. Hardware requirements are IBM/compatible with 640K
memory for maximum capacity. Can be used with 384K
with reduced capacity. Hard drive recommended. Printer
capable of compressed print.

11. Although not copy protected the owner's name - call -
10-10 number and address are written into the program
code.

The program is priced at $20.00 ($25 for DX Air Mail)
and is available on either 5¬" or 3«" diskettes. Please
state disk size (and whether you can user High Density 
disks) - make your check payable to Hardy Data Systems 
and include your name - call and 10-10 number.
